It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.

Guidelines for Modelling Water Sharing Rules in eWater SourceeWater
Water sharing rules are frequently encapsulated in some form of water management plan, or policy, which often has statutory status. Water sharing rules are developed for individual river systems and this can occur for a variety of reasons. For example, the aims could be to maintain or improve ecological functions, sustain the regional economy and protect the social values and benefits of the river system. Fundamental to developing water sharing rules in this situation is an understanding of environmental water needs, water entitlements including their priority of access, basic landholder rights, allocation of water and operation of water accounts. In regulated systems these rules are implemented in practice as operating rules for dams, rules for water allocation, rules governing access to water and water accounts, while in unregulated systems, implementation is via rules governing access to water and water accounts. Rules governing access to water may be attached to licences. Modelling of water sharing rules entails representing the water resource system, its water users, infrastructure details, environmental assets and processes for implementation of these rules.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. A Canada-wide Framework for Water Quality Monitoring i
Executive Summary
A Canada-wide Framework for Water Quality Monitoring is a follow-up to the Canadian Council
of Ministers of the Environment (CCME) Experts Workshop on Water Quality Monitoring
hosted in October 2002 by the CCME Sub-Group on Water Quality Monitoring. This initiative
also responds to the direction set by the Canadian Council of Ministers of the Environment to
enhance water quality monitoring in Canada. The purpose of the Framework is to enhance water
resource management by serving as a guide to jurisdictions in the development and
implementation of water quality monitoring programs in Canada. By using the Framework,
improved coordination can be achieved through more consistent approaches and by identifying
specific areas for inter-jurisdictional cooperation. These approaches would promote the
development of credible, comparable data and information on water quality that could be more
effectively shared and utilized nation-wide.
The Framework recommends high level, nationally-consistent guidance in establishing the
purpose of monitoring, program design, site selection, data management, interpretation and
reporting. The Framework also calls for greater coordination among jurisdictions in developing
tools that could support a Canada-wide network of monitoring sites of national, regional and
local interest. At the sites of national interest, opportunities exist for cooperation on core sets of
variables and/or criteria for selecting key variables of most relevance to the site, water use and
issue, and making the resulting data available to all interested parties.

5. A Canada-wide Framework for Water Quality Monitoring 1
1. Introduction
In May 2001, CCME Ministers agreed to link existing water quality monitoring networks to
ensure that Canadians have access to comprehensive information on the quality and safety of
water. In response, a Monitoring Sub-Group was formed under the CCME Water Quality Task
Group (WQTG) to develop a plan of action.
As part of the action plan, the CCME Monitoring Sub-Group held an Experts Workshop on
Water Quality Monitoring1
to facilitate a national dialogue on Canadian water quality monitoring
and to share information on the current state of the science, technology and best practices in this
area.
The aim of the workshop was to identify opportunities for enhancing linkages among existing
Canadian water quality monitoring networks and to build on the strengths of our collective water
quality monitoring capacities. The workshop participants reached an agreement that
collaboration and coordination among jurisdictions will increase the efficiency, affordability,
currency and credibility of water programs with regard to water quality monitoring, database
management, data interpretation (e.g., guidelines) and reporting. To further efforts in this regard,
there was a consensus among workshop participants to pursue the development of a Canada-wide
Framework for Water Quality Monitoring.
This report outlines a proposed Framework for water quality monitoring. The Framework has
been developed in consultation with members of the Sub-Group, as well as water quality
monitoring experts from each Canadian jurisdiction and international sources. In addition, input
was received from national workshops on the implementation of the CCME Water Quality Index.
The Framework is intended to provide a Canada-wide approach, including a set of guiding
principles. It is expected that this guidance will lead to greater consistency in how water quality
monitoring is conducted in Canada. A schematic that provides an overview of the Framework for
Water Quality Monitoring is provided in Figure 1.

2. Method for Developing the Framework
The CCME Canada-wide Framework for Water Quality Monitoring was developed under the
guidance of the CCME Monitoring Sub-Group, using interview responses obtained from water
quality experts in each jurisdiction across Canada. Important additional information was taken
from the United States, Australia, and other foreign sources.
3. Review of Existing Monitoring in Canada
It is useful to briefly review current water quality monitoring activities in Canada. A national
review was conducted in 2002 and was reported at the Experts Workshop in October 2002. More
details from the review are attached in Appendix 1. Generally, the review showed that
monitoring networks vary widely across the country, but have many common strengths,
challenges and gaps. The key strengths identified were the high level of water quality expertise,
a strong laboratory capacity and field methodology, the potential of watershed and multi-barrier
approaches to improve the overall quality and safety of water in Canada, and the growing use of
web-based and GIS technologies for improving access to and use of water quality data.
Challenges identified in existing monitoring networks included gaps in monitoring programs for
some key threats to water quality, the need for federal-provincial-territorial water quality
monitoring agreements with some jurisdictions and a lack of policy requirements for trend
monitoring in most jurisdictions. There is also a lack of common terminology among databases
intended for linkage, and weaknesses in the linkage between monitoring program results and
policy/decision-making.
Canadian jurisdictions have a great deal of experience developing and implementing monitoring
programs. However, better coordination of approaches, techniques, methods and results would
help strengthen all programs. As well, monitoring results such as improved water protection
following monitoring-based evaluations need to be more visible to senior management.
Additionally, the relevance and usefulness of monitoring information needs to be more fully
explained to the Canadian public. Improved dialogue and sharing of data and experience will
improve monitoring programs across Canada.
4. Purpose of a Canada-wide Framework
This Framework is a guide for jurisdictions in the planning and implementation of water quality
monitoring programs. While each jurisdiction has substantial expertise in doing this, it was
agreed that some degree of national guidance was needed. Additional guidance would help to:
• promote the linkage of distributed monitoring networks where desirable,
• increase sharing of data and information, and
• support a collective effort to achieve water quality objectives.
This document has been designed primarily as a tool for practitioners and is not intended to be
prescriptive.
The Framework is also an important national initiative to help monitoring program managers to
better position their programs with other priorities within their departments. The Framework will
help affirm the collective commitment to strengthen water quality monitoring capacities
8. A Canada-wide Framework for Water Quality Monitoring 4
nationally as the requisite foundation for understanding and managing water resources in Canada.
Finally, the Framework may spark other coordination and cooperative measures, such as broader
data sharing initiatives through, for example, a national on-line portal. This portal could allow
users to discover, access and use information on the design and development of monitoring
programs, including guidance, technical reports, access to provincial and federal web sites, etc.
In summary, the Framework is intended to promote the transfer of data into information and
ultimately to knowledge for the benefit of Canadians and policy makers.
5. Guiding Principles
Canadians want and need to have access to comprehensive information about the quality, safety
and availability of their water, both groundwater and surface water resources. To achieve this,
CCME elaborated a set of principles2
to guide cooperative arrangements for all environmental
monitoring and reporting.
1. Communication of information: There will be open, transparent and timely
reporting of information from monitoring programs, sufficient to meet the needs of
jurisdictions and their obligation to communicate to the public.
2. Mandates respected: Cooperative arrangements will respect the mandates of
jurisdictions and other parties.
3. Shared responsibility: Providing resources and implementing monitoring and
reporting activities is a shared responsibility among federal, provincial, territorial
and local governments, and between governments, industry, academic institutions
and other partners. Identifying these responsibilities is an integral component of
cooperative arrangements.
4. Effectiveness and Efficiency: Parties will plan and deliver monitoring and
reporting activities in a way that makes the best use of public and private resources.
5. Timely sharing of data between parties: Parties will share their data with each
other in a timely fashion to support their activities and to meet their legal, program
and/or international obligations.
6. Third party access to data: Third parties may have access to data for research
and/or analysis other than that for which it was originally collected, subject to the
applicable government legislation, policies and contractual obligations. Third party
discovery and access to these data could be facilitated though distributed and
interoperable data standards and websites.
7. Proprietary information: Parties will protect proprietary information included in
data in accordance with applicable policies and legislation.
8. Cost recovery: Where appropriate, parties may make data, analysis and reports
available on a cost-recovery basis, consistent with applicable government policies.
9. Scientific standards: Parties will respect commitments to national and
international monitoring and reporting protocols, and will work cooperatively to
develop new protocols as appropriate, to allow for the meaningful analysis and
comparison of data and results.
10. Standardized data and data management: Parties agree that data should be
standardized and to respect data management protocols and develop new protocols
2
The Principles are available at http://www.ccme.ca/assets/pdf/m_r_stmnt_of_prncpls_e.pdf
9. A Canada-wide Framework for Water Quality Monitoring 5
as appropriate, to ensure compatibility and facilitate the effective sharing of data,
support data integrity, permit comprehensive data analysis, and protect historical
records.
11. Accountability and transparency: Parties will make information about
cooperative arrangements available to stakeholders and the public, and will consult,
as appropriate, in developing these arrangements.
12. Flexibility: Cooperative arrangements should provide the flexibility to adapt to
changes in technology, priorities, and organizational structures and mandates.
13. Reciprocal notice: Parties will provide appropriate prior notice in the event of
terminating or changing cooperative arrangements.
6. Water Quality Defined
In Canada, “water quality” is a term most identified by society to describe the physical, chemical,
and biological characteristics and conditions of water and aquatic ecosystems, which influence
the ability of water to support the uses designated for it.
Water quality is measured with a wide range of physical, chemical and biological variables,
parameters, indicators and measurements. The chemical and physical characteristics of water and
sediment influence aquatic biota and the ecosystems in which they reside. Biological measures
are viewed as more integrative, while the typical physical-chemical results from water samples
show a “snapshot” of conditions at the moment of sampling.
7. Monitoring Program Design Considerations
Every monitoring program should have a clear underlying purpose and supporting rationale (i.e.,
question or questions being posed and why?), and the intended end use of the resulting data
should be identified. Monitoring is often the most resource-intensive component in any aquatic
resource assessment and management regime. It is imperative that data not be collected for its
own sake; there must be a purpose for every variable or parameter measured.
For generalized guidance, the following diagram shows the kind of factors that need to be
considered in the design and implementation of water quality monitoring programs.

Define and state the objectives of the monitoring program. If
reviewing an existing program, determine if the original
objectives are still relevant. Ensure that the right questions
are being asked.
Use up-to-date methods and locally-relevant considerations
to determine variables, monitoring frequency and site
selection, to enable the program to answer the question.
Make sure field procedures and techniques will generate
reliable and credible data. Develop, document and use
Standard Operating Procedures and include these in metadata
records. Utilize technical innovations wherever feasible. In
the event that data sharing among monitoring networks is
envisioned, consistent methods will yield the most
comparable data.
Use a certified laboratory and develop a field sampling
program in consultation with the lab; ensure sample container
preparation, shipping, sample handling and analysis are
satisfactory. Implement QA/QC program for field sampling
and laboratory analysis and ensure the laboratory utilizes
standard analytical methodologies (when possible) and
reports in standard units of measure. Use defensible
benchmarks (e.g., guidelines or objectives) and locally-
relevant scientific knowledge when interpreting data.
Determine if the objectives have been answered, or could be
answered with more data. If not, re-check program design
elements. Include consideration of QA/QC of data.
11. A Canada-wide Framework for Water Quality Monitoring 7
8. Monitoring Program Objectives
Setting objectives is a critical initial step in establishing a monitoring program. In a country as
diverse as Canada, there are a multitude of possible specific monitoring program objectives. It is
as important to periodically review the current relevancy of objectives for existing monitoring
programs as it is to set new objectives.
The overall objective of water quality monitoring programs is to inform Canadians about the
suitability of water for various beneficial uses in both the spatial and temporal domains. The key
concern in setting specific objectives for monitoring programs is to ensure that the right questions
are being asked about the water quality issue of interest. Canadians want to know if their water is
clean and safe to use (i.e., is it swimable, fishable?), and if water quality is getting better or worse
(i.e., trends). Monitoring programs generate new scientific information about the condition of
water and should be seen as an integral part of an overall water management program within
jurisdictions.
In general, monitoring program objectives can be effectively characterized by addressing a suite
of simple questions:
• What is the program attempting to monitor? What are the issues?
• How much is already known about water quality as it relates to a given issue?
• What degree of change or impact do we want to be able to detect?
• What level of confidence do we want to have in the results?
• Is a study, investigation or impact assessment necessary?
• Is a short-term picture of water quality (i.e., synoptic surveillance study) adequate or do
the underlying questions require systematic measurements over a long-term?
• Who is the monitoring program for? Who will be receiving and using the results of the
monitoring program?
8.1 Examples of Monitoring Program Objectives
There is a wide variety of monitoring program types and objectives in Canada, including:
• To provide assurance that surface and groundwater meet the site-specific water quality
objectives set for its use;
• To investigate the reasons why water in a specific location does not meet the objectives
set for it;
• To establish a record of water quality to use as a basis for developing site-specific water
quality objectives;
• To determine long-term trends or track changes in water quality over time. These can be
due to changes in land or water use;
• To determine the effect of discharges on water quality compared with conditions prior to
the discharges;
• To describe the habitat and/or physical conditions in the water, and its associated biota
and sediment, for use as a baseline, in impact assessment, in state of environment
reporting, and for setting in-stream flow needs;
12. A Canada-wide Framework for Water Quality Monitoring 8
• To evaluate non-point sources that may affect water quality; and,
• To determine the effectiveness of efforts to improve water quality (e.g., changes in land or
water use, or effluent controls).
Within these general objectives, there can be more specific goals. Monitoring program objectives
need to be clear, measurable and precise to properly design the program. For example, a program
established to track changes over time may specifically state that a pre-determined degree of
change should be detectable from the data. This specific objective will drive decisions on
sampling frequency and duration of the program. For nutrient studies, a specific objective may
be that loadings from a specific watershed need to be understood. This specific objective will
drive the variables to be measured and the need for flow data. Further illustrations of specific
objectives could be made available through monitoring program designs posted on a web site
established as a recommended implementation step in this Framework.
9. Monitoring Program Design
Once the monitoring program objectives are established, the next step is to determine the scope
of the program and the specific steps and considerations needed in developing a detailed design.
Moving through distinct steps will assist in developing a program that will generate the kind of
data needed to answer the questions posed, meet the program objectives, and do so as cost
effectively as possible.
Despite the multiplicity of possible objectives for water quality monitoring programs, there are
often two broad sub-sets of monitoring program designs:
• Long-term studies designed to monitor for status and trends; and
• Shorter-term studies, such as for survey or compliance monitoring, designed to support
site-specific studies, investigations, impact assessments or in-stream flow needs
assessments.
9.1 Specific Design Considerations
The following design considerations may be important when establishing long- or short- term
studies (Table 1):
Long-term status and trends monitoring
• Determine the definition of long-term for each program and what constitutes a status and
a trend. Monitoring programs for trends require a duration and sampling frequency that
will reveal a statistically valid trend.
• Decide how much change should be detectable in the data, and at what level of statistical
confidence. Tools such as statistical power should be used to determine both the duration
and frequency of sampling. It is possible, however, that there will be no change even over
long periods of record. A Canada-wide guidance document on statistical methods that is
user friendly and scientifically sound would be helpful in assisting jurisdictions in making
program assessments and decisions.
13. A Canada-wide Framework for Water Quality Monitoring 9
• Water quality is often influenced by flow effects and seasonality. Monitoring sites on
streams and rivers should be established at or near flow gauging stations, if possible, to
take advantage of hydrological data that can directly influence water quality results.
Alternatively, the study design may require that a flow gauging station be established at
the monitoring site or that the samples be flow-weighted (e.g., Equal Discharge
Increments or Equal Width Increments).
• Implementation of in situ technologies for automated and continuous monitoring should
be considered. Sites with this state-of-the-art technology are able to collect, store, and
remotely transmit real-time water quality data.
• In a network of status and trend sites within a province or territory, establishment and use
of a spatial framework (e.g., ecozones, biogeoclimatic zones, watersheds, etc.) can assist
with site selection and defining network “representativeness”. Reporting of results could
also be done on an ecozone or watershed basis.
• For existing sites, assess existing data. It may be determined that after a certain number
of data points, conclusions can be drawn about the degree of variation in some program
variables and adjustments can be made, as necessary. Adjustments could include
dropping or adding variables, or adjusting the number of samples seasonally.
• For long-term programs, careful consideration should be given to a balanced set of
physical, chemical and biological components that will best respond to the objectives and
questions posed. Frequently, long-term sites include only chemical variables with field
observations (temperature, etc.), and no biological or sediment data. The nature of
biological and sediment data is that these may only have to be collected during one time
period each year, even in a long-term study.
• The “polluter pays” principle should be considered in monitoring design. When new sites
are established, or old ones threatened by budget cuts, it may be prudent to engage the
industries or municipalities in the drainage basin that affect the water quality, or benefit
from the data, and seek their support. Some excellent examples of this exist in Canada,
such as the Columbia River Integrated Environmental Monitoring Program (CRIEMP)
that has numerous industrial, government and local stakeholders contributing to one
agreed-upon program on the lower Columbia River.
Shorter-term survey or compliance monitoring
• For specific sector-based industries (e.g., mining, pulp and paper), national guidance on
appropriate program components exists through the Environmental Effects Monitoring
(EEM) program. These can be used as guidance in designing monitoring studies in
other sectors.
• Consider statistical approaches in program design. The right sampling frequency is
often tied to the inherent variation in the data. Unfortunately, sampling frequency often
falls back to “monthly” or “quarterly” without the benefit of an assessment of the actual
frequency that might show important information (e.g., poor water quality during
precipitation events). Evaluate the data to determine if enough has been collected to
allow confident statistical interpretation. There is a need to make good judgments about
sampling frequency. Such an evaluation would tend to make monitoring programs more
effective.
• Review the need for one or more “control” or “reference” sites against which
comparisons can be made with impact sites. These would normally be locations where
14. A Canada-wide Framework for Water Quality Monitoring 10
the influence being measured is not present. This may mean a site located upstream, or
in a different part of a lake or estuary, separated by as much distance as possible.
• Review the need to focus on a specific timeframe for monitoring as it relates to the
issues of interest. For example, the best monitoring time may be during late winter low
flow conditions in a river, or spring or fall overturn in a lake. Monitoring during the
spring freshet, when the majority of dissolved and suspended matter is present, may be
the key consideration in Canadian river monitoring. If agricultural pesticide
contamination is the issue, design of the sampling program around times of application
and potential runoff may be most appropriate. The season may create an opportunity to
collect data that are highly revealing, and reduce the need to repeat at other times of the
year. Increased sampling frequencies during these key periods of time may provide
greater understanding of water quality conditions.
• If monitoring for attainment of water quality objectives, ensure that the correct specific
and supporting variables (e.g., temperature, hardness, pH, etc.) are monitored, and the
monitoring frequency is appropriate to each objective (e.g., five samples in a 30-day
period, etc.).

9.2 Monitoring Site Selection and Classification
The selection of sampling locations is another key component of the program design and also
allows some degree of integration of programs across the country. In addition to the
requirements of the program and its objectives, sampling site locations will often be dictated by a
range of site-specific factors. Practical sampling considerations, such as accessibility and safety
concerns, also play a major role in site selection. Assuming that each jurisdiction may have
several active monitoring networks along with a host of dormant or discontinued sites, the
relative importance of each site within the overall monitoring programs of each jurisdiction can
be ranked by priority. For example, each jurisdiction highly values its long-term trend sites as
they tend to provide the most consistent and reliable historical record. However, even some long-
term trend sites can be abandoned for periods of time and then re-sampled after a period of
dormancy once sufficient initial information (usually at least ten years) has been collected. The
following ranking can be used in these cases:
9.2.1 Sites of National Interest
These would include status and trend stations that are highly valued within each jurisdiction, and
which have long periods of recorded, reliable data. These sites could be ranked as the priority for
national monitoring and reporting. Additional sites of national interest may be in National or
provincial parks, at heritage river sites, at jurisdictional boundaries, or in significant ecozones or
watersheds, or be valuable for informing on influences of climate change. Some criteria could be
16. A Canada-wide Framework for Water Quality Monitoring 12
established for formal recognition of these sites within this Framework. In addition to variables
currently being measured, a core set of variables could be agreed upon.
9.2.2 Sites of Regional Interest
These are trend or shorter-term impact sites not included in the national list, but which generate
data of interest to multiple jurisdictions or users. These may include sites monitored by industry
or lay-samplers, such as volunteers and community groups. These data may not necessarily be
considered a priority for national treatment, but data would be made available as provided by the
guiding principles cited in section 5 above.
9.2.3 Sites of Local Interest
These may include short-term surveillance, impact or baseline sites used in survey or compliance
monitoring to confirm the existence of a problem or that a problem has been solved. These data
would normally be of interest only to the jurisdiction or user that collected them, but could be
shared under the same guiding principles.
The following table describes these three ranks along with the level of national consistency or
coordination that could be attached to each.

17. A Canada-wide Framework for Water Quality Monitoring 13
10. Field Sampling Program
Field sampling is done by all jurisdictions and there may be a wide variation in approaches and
techniques used to collect data. Variations can be identified and differences noted and shared
through the implementation of this Framework. Differences are important considerations when
comparable data are sought and shared across distributed networks. In some situations (e.g.,
remote, inaccessible and high-risk locations), the field sampling component of the program can
be as or more costly than the laboratory analysis of the samples. It is important for all staff
collecting samples to be well trained to ensure that the samples are not compromised. Field
quality assurance and quality control protocols are important factors in retaining scientifically-
valid samples. Recent advances in in-situ technologies for automated and continuous monitoring
and telemetry should be considered as part of a modern integrated monitoring program.
Given the potential variability in field sampling techniques, promotion and adoption of consistent
Canada-wide approaches, although desirable from a network linkage and data sharing
perspective, remains a challenge. A national inventory and assessment of techniques, methods
and approaches is needed to characterize the nature and extent of this variability in Canadian
monitoring programs. Standard Operating Procedures for field sampling should be developed,
documented and used, and included in metadata records. Metadata records, which should be
completed for every monitoring site, are vital for providing context and assisting with data
interpretation and data comparability.
Consequently, it is crucial to take a measured, skilled and organized approach to field sampling.
This Framework offers general guidance when developing a field sampling program. Figure 3
highlights several key considerations (adapted from Australian Guidelines, 20003
).

Monitoring and Reporting – Summary.
18. A Canada-wide Framework for Water Quality Monitoring 14
Figure 3. Steps in Developing a Field Sampling Program
Additional considerations in developing the field sampling program include:
• Sampling site description (site number, geo-reference coordinates, and factors such as
access, representativeness, proximity to a gauging station where applicable, and location
of the control site, etc.). A standard format for site descriptions could be developed and
adopted nationally;
• Sampling frequency (monthly, 30-day average, increased intensity with flow, spring
overturn, etc.);
• Sampling methods for water (surface grab, integrated depth, discrete depth, vertical haul,
dredge type, etc.);
• The numerous sampling methods for plant and animal tissues or sediments (methods
could be available on the web);
• Containers and field preparations required (use of field filtration equipment, field
chemical tests and electrical gear, pre-acidified containers, rinse or not rinse, etc.); and
• Sample preservation and shipment (field DO, use of freezer packs, travel time limits,
etc.).
Identify specific data needs of the program objectives.
Ensure appropriate media are sampled. Avoid sampling
for variables that are not relevant to the issue being
addressed.
Consider automated samplers and consult other
jurisdictions for new techniques and approaches,
especially for sediment and biological samples.
Field measurements include temperature, depth, pH,
dissolved oxygen, air temperature, and weather
conditions.
Trained field staff is important. Field QA/QC could
include provision of duplicate samples, blanks or
spikes provided by the laboratory, or procedures for
legal continuity.
Work with analytical laboratory to properly prepare
sample containers. Follow container filling procedures
carefully.
Ensure preservatives and reagents are fresh and not
contaminated. Ensure that laboratory analytical
requests are met. For example, samples are kept cool,
where necessary, and shipping is within established
time frames.

19. A Canada-wide Framework for Water Quality Monitoring 15
Since field sampling may, in some cases, be undertaken by technical personnel or lay samplers
with limited scientific training and experience, a separate guidance document on national field
sampling guidelines would be a helpful component of this Framework, and could be made
available on-line through a national water quality monitoring portal. Until then, several
jurisdictions have field sampling manuals or documents (Alberta, Saskatchewan, British
Columbia, Quebec, Canada) that could be made available through links to the CCME web site.
Recent interest in expanding aquatic bio-monitoring programs and networks has raised the
importance of field training, which is a key requirement in assuring that credible, comparable
data are acquired for use. Similarly, increasing interest in the deployment of automated water
quality sensors, which result in data rich projects, has underlined the need for clear operational
protocols and adequate training of users.
11. Selection of Variables (Parameters)
In general, the selection of variables to be measured is based on local site considerations and the
objectives of the program, including the water quality issues and water uses of interest. For
example, if the objective is to develop a network for assessing the status and trends of water
quality for the support of aquatic life, one would select parameters having the most significant
influence over the health of aquatic life at that specific site or location.
Even though the reasons for doing shorter-term studies vary widely, the basic designated water
uses are few and consistently recognized across the country. These are water for aquatic life;
source water for drinking water; water for agricultural uses (irrigation and livestock watering),
water for recreation and water for industrial uses. These five basic water uses support the
concept of a common, or core set of water quality variables that are typically used as good
indicators for each. However, the exact set of variables would need to be tailored to land use
inputs. In addition, there may be supplementary variables that apply on a site-specific, case-by-
case basis. Canada’s principal water quality monitoring interpretive benchmarks – the CCME
Canadian Environmental Quality Guidelines for water – are developed according to designated
water uses. Provincial guidelines also complement the suite of benchmarks available. Water
quality data can therefore be interpreted to determine if water uses are being protected.
The following table provides a list of recommended core and supplementary variables for
consideration in monitoring programs based on the water use being protected. This approach is
already well established in many monitoring programs in Canada. It must be stressed that this
table represents guidance only and should be seen as a starting point for selection of variables for
any given program. In all cases, site-specific conditions need to be considered in selecting the
full slate of variables to include in a monitoring program. One reason for this is that some
variables are naturally high in certain geographic regions of Canada and, though they may exceed
CCME or provincial guidelines for the protection of aquatic life, they have healthy ecosystems
that are adapted to the ambient conditions.

Treatment of all surface water used for potable purposes is recommended, and is required by some jurisdictions.
It may be possible to achieve a consensus on a core set or sets of variables so that an assessment
of water quality for a designated use is consistent across Canada. Variations would be expected,
but this would allow the sharing of information more comprehensively on a core set of variables
measured in a similar way across the country. At a minimum, sites of national interest could be
coordinated in this way.
Questions that may also be helpful to consider in selecting variables include:
• Does the variable directly measure the issues of concern?
• Do changes in the variable explain measured changes in the environment?
• Can the variable be measured reliably, repeatedly and consistently?
• Is the variable appropriate given the time frame or scope of the study?
• Is the variable a key determinant for supporting or impairing the water use at the site in
question?
21. A Canada-wide Framework for Water Quality Monitoring 17
12. Laboratory Analyses
There are often many specific analytical techniques to choose from for the same variable.
Appropriate methods can be found by referring to reference materials on standard methods.
Choices need to be made on the basis of what method will reveal the best information to answer
the question posed by the monitoring program. Cooperation with laboratory staff should be
sought when working out the details of best analytical procedures for any given circumstance.
As a general rule, analytical results from laboratories, especially if they support regulatory,
assessment and management activities, should be able to meet the following basic principles:
• The investigator must be confident that all analytical data generated by or received from
the laboratory are reliable as well as scientifically and technically defensible;
• The laboratory can ensure that procedures are documented so that any anomalies,
deficiencies or sources of error can be identified and addressed;
• The investigator can be confident that full value is obtained when purchasing analytical
services;
• The laboratory can show resulting data are consistent with national and international
standards; and
• Results from the laboratory are comparable with those of other laboratories, or at least,
the method details are identified so as to assess the nature and extent of differences among
laboratories.
To achieve these principles, all jurisdictions should only use analytical laboratories accredited for
specific analytical tests under the Standards Council of Canada, the Canadian Association of
Environmental Analytical Laboratories (CAEAL) or an equivalent. Where SCC/CAEAL or an
equivalent accreditation does not exist, the laboratory should maintain full documentation on
QA/QC, be prepared to undergo proficiency testing for the variables in question, and make these
test results available to the investigator. Like field methods, a national inventory and assessment
of laboratory analytical methods is required, and the results should be made available to CCME
member jurisdictions. There are opportunities to identify and share preferred analytical
techniques and protocols for the set of monitoring sites that are of national interest.
The following is a typical sequence of steps in preparing to use a laboratory and receive data:
Identify the analysis required:
• Normally this is driven by the question being posed by the monitoring program.
Select analytical methods and detection limits:
• Include laboratory staff in deciding upon appropriate methods. For example,
determine detection limits in light of precision required and associated costs.
• For most environmental samples, more sensitive analytical techniques should be
selected unless data indicate that a less sensitive method is appropriate.
• Make sure the detection limit specified is low enough to meet the needs of the
study requirements.
22. A Canada-wide Framework for Water Quality Monitoring 18
Consider holding times and sample stability:
• Samples must be shipped to the laboratory within specified times.
• Variables such as pH, alkalinity, and organic and inorganic carbon in water can
vary significantly over a 24-hour period and should be analyzed in the field or as a
first priority in the laboratory.
The laboratory performs the analysis:
• Understand the quality control procedures; request a QA/QC report from the
laboratory.
Receive data:
• Review analytical results from the laboratory immediately.
• Correct typos or other apparent mistakes.
• Check for the need to re-analyze anomalous samples.
• Analytical results should be downloaded directly from the laboratory to the data
storage and retrieval system to minimize human intervention and ensuing errors.
13. Data Management
Data management is a key component of any monitoring program. Data management in water
quality monitoring programs is often complex due to the large number of records generated, the
wide variety of monitoring and reporting objectives, and the wide differences in data
management approaches and IT/IM architectures available and employed throughout Canada.
The complexity of the dataset increases with the broad range of laboratory methods employed.
Data management systems used by various jurisdictions differ considerably with respect to the
manner in which data are received, stored and retrieved. Considerable financial and human
resources are often invested in the development and maintenance of these data systems. The
situational analysis in 2002 pointed out that there was inconsistency in data management systems,
even within the same department.
A good example of a consistent data management tool for monitoring data is the federal
ENVIRODAT, which includes maintenance records for laboratory methods codes. There is
currently an exercise underway to modernize Environment Canada's water quality data holdings
(ENVIRODAT) and provide a reliable central service for managing and distributing
ENVIRODAT codes. This exercise includes the adoption of standards to more effectively
improve the credibility, comparability, accessibility and delivery of these databases. These
standards include collection level and station level metadata, using CSDGM (Content Standard
for Digital Geospatial Metadata) and SensorML, respectively. The other facet of this
modernization includes a comparability assessment of laboratory methods used in water quality.
The guiding principles in section 5 call for good reporting and coordination, and recognize that
data are to be shared with other parties in a timely fashion as appropriate to program needs and
restrictions. Data should be managed in a way that promotes data interoperability and
comparability so that, where required, data/databases from distributed networks and programs
(inter-jurisdictional) can be used together for a common purpose.
23. A Canada-wide Framework for Water Quality Monitoring 19
14. Interpretation of Results
When interpreting the results of field sampling, there must be a linkage back to the original intent
of the monitoring program. The intent is to provide an approach that will serve as guidance
through various steps in the data interpretation process. Each investigator must also use their
experience and understanding of water quality to aid in the interpretation of results.
There are three basic approaches for data assessment:
1. Assessment over long periods of record for the purpose of determining trends and
changes over time (e.g., for trend monitoring);
2. Analyzing the relationships between measured values for variables in the monitoring
program to determine differences and the significance of the differences (e.g., for survey
or compliance monitoring). This may include upstream vs. downstream or control site
comparisons, or other spatial or temporal differences; and
3. Assessment of the extent to which measured water quality meets published guidelines,
criteria or objectives (e.g., for survey or compliance monitoring, or objectives established
within a water quality index).
Prior to conducting the interpretation, data should be prepared and examined in a structured
manner and the appropriate statistical treatments employed. Preferably, these treatments would
have been selected in advance and the program designed to allow the use of the selected
treatment. The steps in data interpretation can be represented in the following diagram (adapted
from the Australian Guidelines, 2000)4
.

Figure 4. Steps in Interpretation of Results
15. Reporting
Reporting on monitoring program results is a critical part of an overall monitoring program and,
in most cases, the integrative component that allows one to measure the overall performance of
the program. The report should reflect how well the questions posed by the program have been
answered. Within government agencies, there can be day-to-day pressures that result in delays in
data interpretation and reporting. It may be helpful to commit time to the reporting as part of the
monitoring program so that this important component is retained.
There are many options for a reporting format. A report should contain many of the elements
described in this Framework: statement of objectives, program design, variables measured, field
techniques, laboratory QA/QC, data management and interpretation, conclusions and

recommendations. The use of web-based and GIS technologies have added a new dimension to
traditional reporting options.
As a Canada-wide Framework, it is important to focus on what is reported and how this could be
done nationally. Based on the interviews conducted across the country, there is not yet a
consensus on the extent to which jurisdictions should report on a Canada-wide basis. However,
the guiding principles and instructions from Ministers lend support to the need for organizing
some form of Canada-wide reporting, particularly on trends.
A reporting mechanism could be an on-line portal established through the CCME web site and
linked to each jurisdiction’s web site. Interpretive and assessment reports from each jurisdiction
could be linked to the on-line portal with instruction on how to obtain copies of reports that are
not available electronically. In addition, depending on the level of comfort and technical
capabilities of each jurisdiction, links to specific monitoring stations could be established and
data could be made available to an outside user. It is recognized that there are restrictions placed
on the use and sharing of some types of monitoring data such as those associated with regulatory
approvals, where data are considered proprietary information and subject to freedom of
information and protection of privacy requirements.
The kind of interpretive and assessment reports that would be posted and available through the
portal could include:
• Descriptions of federal, provincial and territorial water quality monitoring programs and
strategies, and any revisions or annual operational plans;
• Impact assessment reports;
• Short-term baseline studies intended to describe the water quality at specific locations;
• Environmental Effects Monitoring (EEM) Program study reports;
• State-of-Environment (SOE) reports by jurisdictions;
• Reports on long-term trend analysis;
• Reports on the Water Quality Index (e.g., the Freshwater Indicator of the Canadian
Environmental Sustainability Indicators annual report);
• Case studies for existing municipal, forestry, mining, agriculture, and non-point source
monitoring programs;
• Operational manuals such as field sampling protocols, special analytical techniques, and
new field techniques (e.g., the use of in-situ mesocosm apparatus or continuous
monitoring equipment);
• A forum for posting questions and exchanging more detailed technical information; and
• Web-based and GIS tools providing interactive and dynamic reporting capabilities.
In Table 2 of this Framework, monitoring sites of national, regional and local interest are
described. The priority for Canada-wide reporting would be the sites of national interest. This
would include reporting results from a common set of variables, methodologies, and calculated
water quality indices for the agreed trend sites across Canada.

16. Path Forward
As documented earlier in this report, a review of the existing water quality monitoring networks
in Canada demonstrated many strengths, challenges and gaps. The purpose of the Canada-wide
Framework for Water Quality Monitoring was to provide a guide for jurisdictions in the planning
and implementation of water quality monitoring programs. As with all collaborative work, it is
essential to evaluate the importance of the product produced and to determine how this product
can be best utilized to achieve its primary objectives. Development of this high-level guidance
document is a substantial step towards introducing concepts within water quality monitoring that
can lead to national consistency. More specifically, it provides essential information that can be
used to ensure all aspects of water quality monitoring are carried out with the utmost accuracy
and efficiency.
The following are some important steps that will help advance this Framework and at the same
time address some of the challenges and gaps identified within water quality monitoring
networks across the country:
• The Water Quality Monitoring Sub-group under the CCME Water Quality Task Group
should be designated to act as a lead resource group to:
Develop numerous technical documents detailing each element of water quality
monitoring to act as companion documents to the Framework. In light of limited
resources and time, it will be important to identify key gaps and priority needs of
jurisdictions, and to evaluate existing documents prepared by federal or other
jurisdictions that could be used or built upon in the Canada-wide context.
Jurisdictions should be encouraged to use these documents to decrease the sources of
errors that can occur in water quality monitoring programs and to improve national
consistency. Topics of interest may include:
o water quality monitoring program design
o field sampling
o automated sampling
o laboratory analysis
o quality assurance/quality control
o data analysis and interpretation
o statistical methods
o data processing and management
o data reporting
o new/innovative techniques and equipment for water quality monitoring, analysis
(e.g., neural networks for QA of automated data) and reporting.
Define criteria for the selection of national water quality monitoring sites. The
establishment of a national water quality monitoring network(s) should be
multifaceted to include a variety of water body types (estuary; small, medium and
large lakes; streams and rivers; groundwater); representative sampling locations across
the country (e.g., wet coastal areas; dry plains; the mountains and the Precambrian
27. A Canada-wide Framework for Water Quality Monitoring 23
Shield; the north and the south); and representative samples of sites impacted and not
impacted by varying degrees of human activities.
• A link or portal on the CCME web site should be established where a user can access
various products produced under this initiative along with existing interpretive reports,
guidance documents, training manuals, field sampling protocol documents, analytical
methods, etc. The portal would also provide links to the web sites of individual
jurisdictions and to other groups or agencies where the user can pursue additional
information.

Appendix 1. Review of Existing Water Quality Monitoring in Canada
It is useful to review the current situation in Canada on water quality monitoring. A review was
conducted and was reported at the CCME Experts Workshop on Water Quality Monitoring in
October 2002.
The conclusions of the review showed that:
• Monitoring networks vary widely, and have many common strengths, challenges and
gaps.
• Monitoring results need to be more visible to senior management within the generating
agency, and to the public, and the relevancy and usefulness of monitoring information
needs to be more fully explained.
• Better coordination among jurisdictions is a challenge, but also coordination within
jurisdictions needs to improve, and may need to be done as a first step.
• Better linkages among jurisdictions will spread techniques and innovations, even if
specific program details do not change. Improved dialogue and sharing of data and
experience will improve monitoring programs across Canada.
Common elements to build on:
• All jurisdictions have monitoring networks, for long-term and shorter term studies.
• The basic rationale for the long-term trend sites is similar across the country.
• Many common elements and variables are measured in each jurisdiction, with local
differences and field techniques.
• Adoption of a watershed approach to managing water quality is a growing trend.
• There is a recent focus on improving drinking water safety, with accompanying regulatory
and institutional strengthening.
• Monitoring networks are vulnerable to funding reductions due to many factors.
• All jurisdictions have had their programs reduced and otherwise affected by cut backs.
• There is a common use of lay and/or contract samplers to collect samples in the field.
• All jurisdictions report not having full capacity to achieve their water quality goals.
• Some jurisdictions do not want to have their water quality compared to that of others.
Strengths of existing monitoring systems:
• Watershed and multi-barrier approaches have a strong potential to improve the overall
quality and safety of water across the country.
• Procedural improvements have been made to alert communities if bacteriological findings
warrant.
• A high level of expertise in water quality exists across the country.
• Canada has good laboratory capacity and field methods, even if these vary among
jurisdictions.
• The use of Water Quality Index for assessment and public reporting is expanding.
• The use of site-specific objectives and associated monitoring and public reporting is a
growing trend.
29. A Canada-wide Framework for Water Quality Monitoring 25
• Some jurisdictions are using an overall water strategy and policy with monitoring as an
element.
• There is a growing use of web-based and GIS techniques.
Gaps in existing monitoring systems:
• Networks of trend stations are not required as a matter of policy in most jurisdictions, but
persist through the efforts of professional staff.
• Although coordination mechanisms are available through CCME, they are not being used
as a forum for coordinating approaches or sharing stories.
• A common terminology (i.e., parameter vs. variable) is not used among data bases
intended for linkage.
• Long-term data tend not to be written up and reported, creating a problem with the
visibility and value of long-term monitoring.
• Some threats to water quality, as identified in recent reports, are not monitored
adequately.
• Federal-Provincial-Territorial water quality agreements are not in place in all provinces or
territories.
• Coordination between drinking and non-drinking water staff is lacking in some
jurisdictions.
• Linkages can be poor between databases within the same jurisdiction.
• Monitoring program designs may not achieve the desired results.
• Linkages between monitoring program results and policy making can be weak.
