Long Island relies solely on groundwater for drinking water. Contamination from improper disposal of household hazardous waste and excess nutrients like nitrogen are negatively impacting water quality. Nitrogen levels are rising in all aquifers due to septic systems, sewage treatment plants, fertilizers, and agriculture. Common contaminants detected include volatile organic chemicals, MTBE, and pesticides. Over 100 pesticides have been found in drinking water wells. The top three pesticides detected are imidacloprid, atrazine, and metalaxyl. Pharmaceutical drugs are also emerging contaminants being detected in surface and groundwater. Proper disposal of wastes and reduction of hazardous chemicals is needed to protect Long Island's sole source aqu
The Long Island Clean Water Coalition, formed by a group of some twenty eco-non-profits and environmental research institutions large and small have come together to to address the water quality crisis now facing Long Island. Our groundwater is polluted, and therefore our drinking water is at peril. Because our ground water is polluted, so are our lakes, streams and bays. Algal blooms wiping out habitats in our bays, shellfish beds closed because of all the nitrogenous waste now in our water.
This presentation is by Adrienne Esposito of The Citizen's Campaign for The Environment. It powerfully presents the problem we as Long Islanders face, and what we can do to bring Long Island back from the brink of disaster.

An Assessment on Drinking Water Quality and Management in Kakamega Municipalitypaperpublications3
Abstract: Drinking water must be free from components which may adversely affect the human health. Such components include minerals, organic substances and disease causing microorganisms. A large portion of the population in urban areas in developing countries suffers from health problems associated with either lack of drinking water or due to the presence of microbiological contamination in water. This research was conducted in Kakamega municipality with a broad objective to conduct assessment of water quality and management in Kakamega municipality. The Specific objective was to determine the chemical water quality parameters in water and to evaluate the management practices on water in Kakamega municipality. Four water quality parameters; two physical and two chemical were tested from the samples collected for this research work. Sampling technique was purposive where water samples from water sources and distribution points in densely populated areas of Kakamega municipality were taken. Data collection instruments that were used included sterilized bottles to collect water, delivery to the laboratory within six (6) hours of collection for reliable results and data quality control was achieved through immediate entry in the pre-designed data form. According to the results pH values at all the sources and house connections are well within the WHO desirable limit of 6.50-8.0. The sample from Sichirai had a pH of 7.8 that was the highest as compared to an Isiukhu river that had 6.6 pH. The samples from Isiukhu river, Savona Island River, fishpond at bridge and Shikhambi spring showed more than 5 NTU. The researchers recommended for water surveillance in Kakamega municipality in order to ensure consumers have safe water free from agricultural and industrial chemical pollution.
This presentation was given at the EPA’s National Water Event 2019, which took place on 29 and 30 May 2019 in Galway. This presentation by Ray Parle from the Health Service Executive is on the risk assessment associated with drinking water and the HSE's role in drinking water.

DEVELOPMENT OF MATHEMATICAL MODEL TO PREDICT THE TRANSPORT OF E.COLI IN A NAT...IAEME Publication
Development of mathematical model to predict the rate of microbial depositions (E.coli) in a natural pond has been carried out. The models were developed to monitor the rate of concentration at different periods, with respect to the length of the pond at various sample station. Results of the theoretical values were compared with the experimental analysis. The analysis was thoroughly done to determine the physiochemical parameters of the pond. Microbial traces were found from the experimental analysis at different periods up to hundred days. The developed model compared favourably well with the experimental values. The values explain the rate of microbial growth and level of lag phase condition. The growth rate of the microbes were found to be higher because there is high deposition of substrate for growth and energy, while at some periods it degrades showing that the substrates have reduced in concentration including the inhibition from the pH. In some cases when the microbes developed lag phase condition it may be as a result of other environmental factors. Finally, the growth rates are between fifty and hundred days, showing that there is constant regeneration of the microbes including other environmental factors.
Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment Systemijtsrd
This paper emphasized on "Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment System". KanDawGyi Lake is used for wastewater collection. It is situated in ChanMyaThaZi Township, Mandalay and near the AyeYarWaddy river. Residential, commercial and industrial area are existed surrounding the KanDawGyi Lake. Water from human activities such as cooking, bathing, washing and septic tanks effluent is discharged into drains by gravity flow without treatment. Average six million gallons of wastewater discharged from Mandalay City area flow into KanDawGyi Lake passing through ThinGaZar creek daily. So, lake water has been contaminated by domestic wastewater. This has resulted detrimental effects on the ecosystem. Water in recreation center should be aesthetically pleasing and essentially free of toxicants and pathogenic organisms. Seven collection points such as entrance, east of north side, south east of north side, south of north side, water fountains, PyiGyiMon barge and exit of KanDawGyi Lake are chosen to collect the wastewater sample. The water quality of KanDawGyi Lake is evaluated by various parameters such as temperature, turbidity, suspended solids, dissolved solids, pH, total alkalinity, total hardness, biochemical oxygen demand, dissolved oxygen, chlorides, total solids and bacteria. According to test results, alkalinity, chlorides, dissolved solids, suspended solids, and total solids are uncertified. Therefore, in this paper wetland design of natural treatment system is used at the entrance of the lake to control the water pollution.

Water pollution is one of the major global environmental problems. It is an acute problem almost in all major rivers and water reservoirs in India. Water pollution is increasing and becoming severe day by day and posing a great risk to human health and other living organisms. There is growing concern on the deterioration of ground water quality due to geogenic and anthropogenic activities. Present investigation aims at insight about the level of contaminants of surface water, groundwater and sediment analysis of selected rivers of Krishna River located in Mahuli and Urmodi river located in Nagthane, Satara district. An attempt has been made to assess the water quality, sediment analysis of the samples. Dissolved oxygen content of the water samples was observed quite well in limits such as in Krishna river Mahuli DO was 27.68mg L and in Urmodi river Nagthane was13.68mg .In the present study, COD value was observed by 720mg l at surface water of Krishna River Mahuliand 1320 mg l at surface water sample of Urmodi river Nagthane. As expected groundwater samples showed values of hardness within a limit. There is an urgent need for more representative samples to be used to go beyond preliminary assessment as reported in the present study for making appropriate recommendations.

What is pollution?Definition – unnatural by-products of human activities accumulating in the environment at levels that are harmful to living organism.
Sources of pollution vary
Some specific types of pollution:AcidOrganic ThermalPharmaceuticalSalinity
Acid PollutionDefinition:
sulfur and nitrogen oxides react with air in the atmosphere (and potentially the terrestrially via run-off) to form sulfuric and nitric acids which will reenter the environment via rain.
Acid pollution is extremely detrimental to all organisms (auto- or heterotrophic) in the environment
Acid Rain is a prime example of Acid Pollution.Rainwater with a pH <5.6 = acidic.Side effect of air pollution from industry.

Organic PollutionDefinition:
compounds that are resistant to environmental degradation
Examples: Pesticides, fertilizers, detergents, sewage, farm run-off
Organic pollutants canBe persistent in the environment for a long period of timeThey accumulate in human/animal tissues and magnify in food chains.a.k.a. They have significant impacts on human health and the environment as a whole.Are capable of long-range transportCan provide large quantities of of organic compounds and limiting nutrients, which act as substrates (food) for microorganisms, are released into water sources (algal blooms)

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.
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

Long Island is a sole-source aquifer region, which means we residents rely on
groundwater for 100% of our drinking water. A clean, healthy aquifer system is vital
to maintaining Long Islanders’ quality of life. Contamination of groundwater from
improper household hazardous waste disposal negatively impacts public health, our
environment and pollutes groundwater supplies.

From Draft Comprehensive Plan Introduction of 12/7/2010
“Much of the County’s ground and surface water resources
continue to meet the water quality criteria established to
assess resource suitability for its best intended uses.”
“Nevertheless, the data also shows a continued and gradual
decline of water quality. Unfortunately, these concerning
trends identify the need for increased water protection
efforts at the County level (ES-1) .”
5. Summary Findings – Nitrates
Septic, Sewage Plants, Fertilizers
Nitrate pollution is largely due to human settlement
Negatively impacts groundwater, marine & freshwater ecological
resources.
Nitrate levels are increasing in all Long Island aquifers
Total Upper Glacial Public Supply Wells – up by 40% (4.34 mg/l)
Total Magothy Public Supply Wells - up 200% (3.4 mg/l)
Deeper supply wells now used to reach cleaner water
1/3 of private wells tested exceed nitrate targets (4-6
mg/l)
Approximately 10% exceed 10 mg/l MCL threshold
6. Summary Findings – Nitrates
Septic, Sewage Plants, Fertilizers
“Sanitary wastewater management is the most important
factor affecting nitrate levels throughout most of the County.”
Many sewage plants (STP’s) reduce nitrates, but SCDHS faced
recent “challenges” getting nitrate compliance from STP’s
Proliferation of smaller plants more difficult to monitor & maintain
1MM Suffolk residents use 340,000 on-site wastewater systems
Nitrate reduction very limited & highly variable (10-50%)
60% of residential properties in Suffolk do not meet minimum
lot size to achieve Article VI drinking water protection goals
<10mg/l
7. Summary Findings – Nitrates
Septic, Sewage Plants, Fertilizers
Fertilizers are “a significant source of Nitrogen in the aquifer”
Agriculture is “a major source of Nitrogen contamination”
Nitrogen varies depending upon the crops grown
Row crops 13.4 mg/l
Vineyards 5.1 mg/l
Suffolk Fertilizer Ban (12/1- 4/1) – Effective 2009
Imposed to foster less aesthetic use of fertilizers residential turf
Program assessment due 2014
8. Key Goals of Comp. Water Plan
Nitrogen should be reduced to the greatest extent
feasible and practical for the protection of current and
future drinking water supplies and the ecological
functions of streams, lakes, estuaries and marine waters.
Groundwater Nitrogen inputs in the County’s surface
waters should be reduced consistent with the goals of
the Long Island Sound Study, Peconic Estuary and South
Shore Estuary Reserve Programs, to protect, preserve and
restore the estuaries
9. Critical Conclusion
“A very basic, but essentially important policy question looms for Suffolk
County.”
“At the completion of the prior Comprehensive Plan in 1987, and for years
thereafter, Suffolk County was proud to be in the forefront nationally of
groundwater research, investigation, and protection programs.”
“In view of recent economic difficulties confronting all municipalities, will
the County of Suffolk have the ability to commit technical staff and
resources necessary to plan and implement the water protection
strategies and recommendations developed by this plan for the next
several decades.”
10. The 3 most frequently detected
VOCs:
Tetracloroethene (PCE)
Trichloroethene (TCE)
1,1,1-Trichloroethane (TCA)
Volatile Organic Chemicals
These are found in a range of products
including:
• paint strippers,
• office supplies,
• aerosols
• cleaning products
11. Volatile Organic Chemicals
VOCs used in the most common products of HHW were
found at high concentration in the Magothy Aquifer,
which is main aquifer used for drinking water.
PCE was present in 4x more wells in 2005 than in 1987.
Levels of TCE increased 150%
In 1987, 1 well exceeded drinking water standard of 5
ug/l. In 2005- 9 wells exceeded drinking water
standards.
12. VOC (PCE) were present in 4x more wells than in 1987.
Levels of TCE increased 150%
Volatile Organic Chemicals
13. Household Hazard Waste (HHW) refers to any
commonly found household items with the potential
to ignite, cause a violent chemical reaction, be a
dangerous corrosive, or be harmful to human health.
The average person accumulates 6 pounds of
household hazardous waste per year, and every year
over 100,000 tons of this waste is disposed of
improperly in New York.
Household Hazardous Wastes
14. Detected in 330 public supply
wells in SC from 2000-2005
Detected in 16% of raw
groundwater samples collected
from all supply wells.
Detected in 10% of private wells,
with 1.4% exceeded drinking
water standard of 10ppb.

15. Long Island Pesticide Use Management Plan: A Decade Overdue
Under development since 1998, the goal
of the plan is to protect Long Island’s sole
source aquifer from pesticide
contamination.
Recently the DEC released a plant to the public
that does not take action to protect drinking
water from pesticides.
In 2000-2001, 834 private and non-community drinking water wells were tested on LI
for the frequency and co-occurrence of pesticides with other pesticides and pesticide
degradates. Results:
• pesticide related compounds were detected in 422 wells (50.6%) of the wells
• more than one pesticide related compound was found in 323 (38.7%) of the
wells
• 5-9 pesticide related compounds were detected in 127 (15.2%) of the wells
• 10 or more pesticide related compounds were detected in 4 (.5%) of the wells
16. Extensive investigations have identified 117 pesticides
in drinking water.
The Top 3 pesticides found in drinking water include:
Imidacloprid
Atrazine
Metalaxyl
Pesticides
17. The NYSDEC documents 117 pesticides in our groundwater. We need to
work to ban the top 3 most detected: Atrazine, Metalaxyl, and Imidacloprid.
Metalaxyl: Detected 1,327 times in 546
locations. Linked to kidney and liver
damage & toxic to birds
Atrazine: Detected 124 times in 51
locations. Banned in European Union in
2004 because of persistent groundwater
contamination.
Imidacloprid: Detected 890 times in 179
locations. Has been found in
concentrations as high as 407 ppb
(Standard 50ppb).

21. Pharmaceutical drug contamination in our
groundwater, rivers, estuaries, and bays is an emerging issue
throughout our state, and our Nation.
41 million Americans drinking water from a source containing trace
amounts of pharmaceutical compounds.
In 2002, the United States Geological Survey (USGS) found trace
amounts of antibiotics, hormones, contraceptives and steroids in 80%
of the water they tested.
Pharmaceuticals
22. Emerging Contaminant: Pharmaceutical Drugs
In 2002, USGS and US Department of the Interior partnered
with the Suffolk County Water Authority to complete a study
on Suffolk County groundwater.
Of 70 samples collected from 61 wells in the upper glacial and
Magothy aquifers, 28 samples contained at least one PhAC
compound.
In 2002, the United States Geological Survey (USGS) found
trace amounts of antibiotics, hormones, contraceptives and
steroids in 80% of the water they tested.
Synthetic steroids, such as estrogens, are known endocrine
disruptors. Trace amounts of these compounds are known to
cause feminization, reproductive problems, and hormone
system disruption in fish.
