This document summarizes water management practices for hydraulic fracturing in unconventional reservoirs in Argentina. It discusses water sources used, types of stimulation treatments performed, and water logistics. The primary water sources are rivers and underground wells in the Neuquén Basin, which meet requirements for use in fracturing fluids. Stimulation treatments in the Vaca Muerta shale play typically use hybrid slickwater followed by gel systems. Water volumes used can range from 5,500 m3 for vertical wells to 18,000 m3 for horizontal wells. The document also outlines typical fluid systems used and some area-specific variations.
Hydraulic fracturing has been used in Argentina since the 1960s and water management practices for shale development have evolved significantly. For the large Vaca Muerta shale play in Argentina, water sources include rivers, lakes, and underground wells. Water is transported using trucks and pipelines and stored in mobile tanks and lined pits. Early exploration used vertical wells requiring around 6,500 m3 of water while current horizontal wells use around 14,500 m3. Stimulation typically uses hybrid treatments combining slickwater, linear gel, and crosslinked gel depending on the reservoir fluid. As development continues, produced and treated flowback water are being tested for potential reuse in fracturing fluids to reduce freshwater usage.

Hydraulic Fracturing and Marcellus Shale Gas 11 22 2011Michael Klein
The drilling technique of Hydraulic Fracturing has allowed natural gas producers to extract natural gas economically from deep shale formations. This innovative drilling technique has made enormous quantities of natural gas available in wide areas of the United States from Texas, Louisiana, Pennsylvania, New York, Wyoming, North Carolina, and Colorado. The drilling technique of hydraulic fracturing accounts for roughly a quarter of total natural gas production in the United States as cited by the Energy Information Administration. With the increased emphasis on the use of natural gas in our federal energy policy, there will be new regulations, processes, and resources that will be required to mitigate the risks to human health and the environment from this new drilling technique. The presentation discusses the process of hydraulic fracturing; the threats that are posed to human health and the environment, areas in the USA where the process is used with an emphasis on the Marcellus Shale formation, current and new regulations being put into place, and plaintiff challenges to the process.

Integrated urban water management singapore's experience and lessons learnt...Global Water Partnership
Singapore faced significant water challenges as a small island nation with a high population density and rapid growth. Through integrated urban water management and a "four national taps" strategy of catchment water, imported water, NEWater, and desalination, Singapore has developed a resilient and sustainable water supply. Key lessons include treating water as a strategic issue, having a single agency manage the water loop holistically, increasing supply through various sources while managing demand, and engaging stakeholders through pricing, community programs, and industry partnerships. Singapore shares its experience through hosting the annual Singapore International Water Week to foster global collaboration.
The document discusses water management and the hydrologic cycle. It describes how water evaporates from oceans, rises through the atmosphere, condenses to form clouds, and falls as precipitation over land and into streams, underground, or absorbed by plants. It also discusses water contamination from biological, chemical, and industrial sources, as well as problems like depletion of water tables, pollution, and scarcity. The Philippine Clean Water Act aims to protect water bodies from pollution through multi-sectoral cooperation and enforcement.
ASSESSMENT OF WASTE WATER TREATMENT IN CANAANLAND, OTA, OGUN STATE, NIGERIA.O...Felix Oginni
Effluent from a sewage treatment plant in Covenant University, Canaanland is made to pass through a series of constructed wetland before discharging into a gully that drains into River Iju (also known as Atuara). This river is used as a source of drinking water and also provides food in form of fish for hundreds of thousands of people downstream and eventually enters the lagoon, some 60km away. Effectiveness and adequacy of the wastewater treatment facility in place was assessed in order to improve sanitation within this watershed, thereby alleviating environmental challenges in this coastal region of Nigeria. Waste water is gravity drained to the southwest portion of the campus where the solid is removed and the liquid is allowed to flow through six sets of constructed wetlands, each with four chambers. Within each chamber are water hyacinth plants put in place to remove nutrients from the waster water.
A quick survey of the facility shows the system to be effective in reducing and removing solids and dissolved solids from the waste water. The pH ranged between 6.6 and 6.8, conductivity from 530 to 600, and total dissolved solids (TDS) ranged from 360 – 400 ppm. The data obtained indicate that some modifications need to be made as the waste water treatment system is not very efficient in reducing the amount of TDS and nutrients. The flow rate is considered to be very high from cell to cell, thereby not allowing time for the plants and microbes to reduce the TDS. It is suggested that some method be devised to slow down the flow rate to allow the plants and microbes to work on reducing the TDS. Parameters also also considered included DO, E. Coli. Nitrate and Phosphates.
Maintaining Stormwater Systems (Rain Gardens) - Northern VirginiaSotirakou964
The document provides a guide for private owners and operators on maintaining stormwater systems in Northern Virginia. It discusses the history of stormwater management, beginning with drainage ditches and evolving to include water quality treatment and a watershed approach. The guide describes various stormwater management components, such as dry ponds, wet ponds, rain gardens, and permeable pavement. It offers tips on inspecting, maintaining, and troubleshooting these systems to improve stormwater quality and reduce flooding issues.
Water pollution comes from a variety of sources including agriculture, industry, mining, urban runoff, and sewage. It harms living organisms and humans. Surface water pollution can be reduced through regulations and technologies that treat industrial and municipal waste. Groundwater pollution is difficult to address due to slow flow rates and few bacteria to break down pollutants. Solutions aim to prevent pollution at its sources and purify drinking water supplies.

4. Well Life Cycle
Groundwater basics
Your well gets its water from an underground water source
called groundwater.
Infiltration Groundwater originates from surface water and
precipitation, including rain and melting snow, that has
infiltrated the earth, filling the cracks and open spaces in the
rocks and the soil. Saturated layers below the water table
that store and transmit significant quantities of groundwater
– i.e., enough to supply a well – are called aquifers.
Keeping it clean
Surface spills of contaminants like fuel can
infiltrate the soil and contaminate groundwater.
The risk of contamination is greatest where the
ground surface is highly water permeable, e.g., in
areas with coarse soils or fractured bedrock at or
near the surface.
Groundwater can also be contaminated by
underground sources, such as leaking fuel
storage tanks or malfunctioning septic systems.
Poorly constructed or deteriorating wells can act
as a direct pipeline for surface pollutants to
contaminate the aquifer. Unused and
Water unmaintained wells are a special concern if they
Table haven’t been safely plugged and sealed.
Depending on the type of soil or rock,
Aquifer groundwater may be filtered and very clean. But
once an aquifer is contaminated, it can take a
very long time to recover, if ever.

Groundwater flows
It is impossible to determine the exact direction of groundwater flow based on
surface features alone. However, we know that water in the aquifer near a
pumping well will flow toward the well.
The danger of groundwater contamination is greatest when the contaminant
source is close to your well. However, on rare occasions contaminants have
been known to spread over several kilometres.

7. Well Life Cycle
Dug Wells
Dug wells are at higher risk of contamination than drilled
wells because they obtain water from shallow groundwater
aquifers. Contaminants are more likely to be found closer to
the surface (see Protecting Your Well Water, p.13). If you
own a dug well, be sure to test it often and consider
replacing it with a drilled well if your water supply is not
adequate or safe.
Shallow wells are at
a higher risk of
contamination than
drilled wells.
Dug wells are typically 3.7m - 7.6m (12-25 ft)
deep and have a diameter of about 1 m (3.3 ft)

8. Well Life Cycle
Locating a new well
If you are constructing a new well, think
carefully about the best location, that is, a
high point of land with good access and
separation from potential contaminants.
Contact a Department of Environment and
Conservation licensed well driller to locate a
drilled well on your property. Contact a
Government Services Centre approved
designer for dug well construction
information.
The ground must slope
away from the well
Locate your well on a higher point of land so
that run-off and contaminants drain away
from the well rather than toward it. The area
nearby can be landscaped and contoured to
help direct run-off away from the well.
Access
Wells and well-related equipment must be
sited so they can be easily accessed at all
times for cleaning, treatment, repair, testing,
and visual examination. During the winter
months, remember to clear snow from the
area surrounding your well.

Separation from contaminants
Wells must be located a safe distance from potential sources of contamination such as fuel
storage tanks, stockpiles of chemicals like pesticides or road salt, septic systems, gardens, manure
piles, livestock, and roads and driveways.
The following tables show minimum required distances between wells and possible contaminants:
Drilled wells: Dug wells:
• 15 m from septic tank systems •15 m from septic tanks
• 30 m from cesspools of sewage •30 m from septic fields
• 1 m from pumphouse floor drains •30 m from all other potential
contaminants
• 2 m from buildings
• 75 m from manure spreadings on
• 75 m from manure spreadings on agriculture fields
agriculture fields
These minimum distances do not guarantee safety. Increase the separation wherever
possible, and eliminate sources of contamination.
Well Aware A Guide For Well Owners 7
10. Well Life Cycle
Well construction
A properly constructed well forms an
effective barrier against surface run-off
that may enter and contaminate the
well.
Water must infiltrate and pass
downward through the soil and/or rock
before it can reach the aquifer from
which your well gets its water.
Over the years, well design has
improved to reflect advances in
technology and our understanding of
potential pathways of contamination.
The Well Drilling Regulations, under
the Water Resources Act, outlines
minimum construction requirements for
drilled wells. Always hire a well driller
licensed by the Department of
Environment and Conservation who is
familiar with these regulations.
Dug wells must be designed in
consultation with an Environmental
Health Officer (EHO). It is difficult to
make a dug well as safe as a drilled
well.
Well casing
New wells should be lined with a watertight casing designed to prevent the walls of the well from
collapsing. Well casings must be of sufficient length to keep contaminants out of the well water.
Steel casings are typically used, but casings can also be made from plastic.
8 Well Aware A Guide For Well Owners
11. Well Life Cycle
The annular seal
When your well is drilled the hole in the ground is bigger than the well casing. The
resulting gap – the annular space – must be filled with a watertight sealant such as
bentonite that does not shrink or crack under the ground. For maximum protection,
the sealant should extend the full length of the casing.
The annular seal serves as a barrier to run-off, surface water, and near-surface
waters that could otherwise travel down the outside of the casing and contaminate
the aquifer.
Well cap
Your drilled well must be capped with a commercially manufactured vermin-proof
well cap. Vermin-proof caps have rubber gaskets and screened vents inside to prevent
entry of “foreign material” such as vermin, insects, and decaying plant material.
Loose fitting caps found on older wells make these wells a comfortable home for
insects and vermin.
Well Aware A Guide For Well Owners 9
12. Well Life Cycle
Upgrading your well
It is possible – even likely – that your existing well
does not meet the new construction standards
described in the preceding section. What should you
do?
Consider upgrading your existing well for the sake of
your family’s health and safety and the security of your
drinking water source.
Faulty annular seal.
Talk over your options with a DOEC licensed well
driller or EHO who is experienced with upgrades and
familiar with conditions in your area.
Upgrade your well,
or construct a new one?
If there are water quality problems with your existing
well, one option is to drill a new well.
A new well may be the best way to go if your existing
well is:
• badly located, close to permanent sources
of contamination, or at risk from flooding
• not producing adequate water supplies
• substandard and cannot be upgraded for
technical or regulatory reasons
10 Well Aware A Guide For Well Owners
13. Well Life Cycle
Do you have a high risk well?
Some wells are at higher risk of contamination and require extra care and attention. Consider the
following factors:
• shallow, or dug, wells, less than 6 metres (20 feet) deep, are at higher risk than deeper, or
drilled, wells because the water table is closer to the surface and can be contaminated more
easily;
• older wells are at higher risk than newer wells because of casing deterioration and older,
less advanced, well construction methods.
Another important risk factor is the type of soil and/or rock between ground surface and the
aquifer from which your well draws its water. Put simply, your well is at lower risk if these
materials effectively stop surface contaminants from reaching the aquifer; it is at higher risk if
contaminants can infiltrate more rapidly.
For example, coarse soils like sand and gravel are a less effective barrier than thick deposits of
fine soils like clay loams or silty clay. If your well ends in bedrock, which is likely in
Newfoundland and Labrador, it is at higher risk if bedrock fractures extend to ground surface or
near the surface.

that hasn’t been properly plugged
and sealed poses health and safety
hazards for animals and humans,
especially children.
A well that is no longer used or maintained can become a
direct pipeline for surface water or run-off to reach the
aquifer. Unused and unmaintained wells threaten the
groundwater that supplies your well, and possibly your
neighbours’ wells.
It is your responsibility under the Well Drilling Regulations to ensure that your unused
wells are properly plugged and sealed.
Don’t try to seal your own well – it is not as easy as it seems. If you simply fill up your
unused well with sand, gravel, stones, debris, or garbage, you won’t prevent the flow of
surface water or run-off into the well. The material in the unused well may even
contribute to contamination of your groundwater source.
If an unused and unmaintained well is on your property, you are
legally responsible for ensuring that it is plugged and sealed properly.
Hire a DOEC licensed well driller who has the expertise and equipment to do the job properly.
Newfoundland and Labrador has guidelines for sealing drilled groundwater wells that require
filling the well with alternating layers of bentonite clay and sand or local soil. Dug wells can be
filled in with clean, local soil and any exposed well liner should be removed.

The following sections of this booklet will show you
how.
Well water protection starts at home
The most immediate threats to the safety of your well water are usually nearby – in your own
yard.
As part of your routine well maintenance schedule, walk the grounds surrounding your well. Look for
potential threats. A complete search for potential contaminants is recommended, at the same time as
you inspect your well (see pages 21-22). You should also look for changes that could affect your well
as part of your daily and weekly routines.
Keep these contaminants away from your well:
• pet and livestock wastes
• gasoline, diesel, home-heating fuels
• pesticides and fertilizers (chemical or natural)
• other hazardous chemicals, including paint, solvents,
barbecue starter fluid, etc.
• de-icers (used to melt ice on roads, driveways, sidewalks)
• and any other substance you don’t want in your family’s drinking water.
Well Aware A Guide For Well Owners 13
16. Well Maintenance
Never hose down spills.
Chemicals and fuels
Any chemical or fuel spills that infiltrate the ground can contaminate your drinking water source.
Check that gasoline, pesticides, and other chemicals are stored in proper containers designed to
help prevent spills or leakage. Don’t store these materials anywhere near your well.
• Refuel lawn mowers and other machinery a safe distance from the well. (One litre of
gasoline can contaminate 1 million litres of groundwater.) Refuel over hard surfaces to help
prevent infiltration of spills.
• Change the oil in your vehicle on a sealed surface such as
pavement or concrete away from the well.
• Clean up spills with an absorbent material, such as clean
sand or kitty litter. Keep a bucket nearby for quick access
when spills occur. Material used to clean up spills should be
disposed of properly. Contact your local municipality for
Household Hazardous Waste Days in your area.
Fuel and chemical leaks and spills
can pollute groundwater.
Septic systems
Locate your septic system down grade and away from your well.
Ensure that your system conforms with the Sanitation Regulations
under the Health and Community Services Act. Keep chemicals
other than human waste out of the system. Pump out your septic
tank every two to three years, or ask your pumper to specify the
appropriate pump-out frequency. Keep your system in good
running order by conserving water (see pages 19-20).
Gardens
Eliminate gardens adjacent to your well. Plant a permanent low-
growing ground cover such as grass. Don’t use fertilizers or
pesticides.
14 Well Aware A Guide For Well Owners
17. Well Maintenance
Underground storage tanks
Underground storage tanks and associated pipes and fittings, particularly valves, may leak, especially
if they are over 15 years old or lack corrosion protection. Underground storage tanks are a special
concern if the water table is shallow, or if the tank is close to your well (or surface water). If possible,
replace underground tanks with above ground storage that has proper spill/leak containment.
Underground heating oil storage tanks with only one wall will not be
permitted in Newfoundland and Labrador after March 31, 2007.
Above-ground storage tanks
If storage tanks are required, keep them as far as possible from
your well. Install sheltered tanks with spill containment, as
required by regulation, capable of holding 125 per cent of the
volume of the tank. Security and protection from damage are
advisable.
In Newfoundland and Labrador,
heating oil tank owners must register
their tanks on or before March 31,

sticking out of the ground. An abandoned tank
may still contain harmful liquids that will leak
as the tank corrodes.
Animal wastes
Livestock and pet wastes are a serious potential threat
to well water, as the Walkerton, Ontario tragedy
showed. Keep livestock and pets away from your well at
all times.

Contaminant sources affecting your well are most often found in your
own backyard. Address these first. However, you should also support
actions to protect all sources of drinking water for your community.
Municipal land-use plans need to identify vulnerable ground and surface
waters. Land-use plans should provide the necessary protection through
controls on the location, amount, and type of development.
Major sources of contamination need to be curbed, like polluting
industries and urban and agricultural run-off.
Programs need to be in place to reduce risks of groundwater
contamination from unused wells, open excavations, quarries, and
contaminated sites.
Get involved in protecting sources of drinking water for
your community. Contact your municipality for
information.

19. Well Maintenance
Inspecting your well
It is the well owner’s responsibility to maintain their well - to keep out
surface run-off and foreign materials.
It is recommended that you conduct an inspection of your well at least once
a year, as outlined below, at the same time as you check for potential
contaminants (see page 13).
If you’ve got problems with your well water, or concerns about your well,
have your well inspected by a DOEC licensed well driller.
Access
As part of your maintenance routine, keep your well clear of brush, debris, snow and other
obstructions.
Well cap
Check the well cap for signs of cracking or damage, and get it fixed or replaced immediately if
there is a problem. The well cap should be firmly attached to the casing. The vent should face the
ground and be properly screened to keep out insects. Only air should enter. The well cap should
be above ground and exposed at all times; cleared from snow, leaves and other obstacles.
Annular seal
Look for problems with the sealant used to fill the annular space between the drilled hole and the
well casing. A depression in the ground around the edge of the casing can indicate
that the sealant has shrunk, collapsed, or cracked. If you can move the casing
around by pushing it, that’s a bad sign. Cracking and gaps allow run-off and
surface water to move down the outside of the well casing and contaminate your
drinking water. A faulty annular seal needs to be repaired. Call a DOEC licensed
driller.
Well Aware A Guide For Well Owners 17
20. Well Maintenance
Well casing
Look for any external signs of damage, cracking,
or dislocation of your well casing, e.g., due to
vehicle damage. If you’ve got a small diameter
well (drilled), removing the cap is not
recommended. Visibility is limited and you could
cause contamination or damage, especially if you
have a submersible pump. Some licensed well
drillers can inspect your casing with a down-hole
camera. If you’ve got a larger diameter dug well,
you can remove the lid with care. Inspect the inside casing using a strong flashlight. Look for
holes or cracks, including evidence of animal infestations, or stains coming from the casing joints.
Backflow prevention
Under certain circumstances, contaminated water can flow backwards through your plumbing
into your well. Backflow prevention devices are available from your licensed well driller or pump
installer.

personal greenhouse gas emissions (GHG).
Avoid Water Shortages!
Many well owners have experienced their well going dry at one time or another. Help
prevent water shortages by using water wisely.
Help Your Septic System!
Too much water flowing through the septic system can cause problems and lower the
life expectancy of your system. One study conducted found that overuse of water caused
75% of septic bed failures.
Conserve Energy and Save $$$!
Using less water means less energy is required for pumping,
heating and treating your water. Making small changes can
make a big difference in your energy bill. Replace your
regular showerhead with a low flow version and save 25% of
shower water annually, that’s cash in your pocket!
Be Kind to Mother Nature
By conserving water, you will be aiding Canada in its effort
to protect our precious groundwater resource as well as
reduce greenhouse gas emissions. About 29% of this Province’s population relies on
groundwater. It is essential that we help protect this valuable water supply by properly
maintaining and protecting our wells.
The average Canadian produces
five tonnes of GHG a year. Check

Tips to help you conserve:
Use Water-Saving Devices
•Use up to 50% less water in your toilet by using an ultra low-flush 6-litre version.
Dual-flush toilets can save 68% of water used by supplying separate flushing
mechanisms for liquid and solid waste.
•When replacing your clothes washer, consider a front loading washer - they use 40%
less water than top loading washers.
•Attach aerators to all your taps to reduce water consumption by 25%.
Repair Leaks Quickly
•Leaks can waste thousands of litres of water if they are A leak of one drop per

water system. That's money down the drain.
Use Water Wisely
•Never let water run continuously while washing dishes or brushing teeth.
•Collect rainwater and use it to water your garden. If you must use a water hose, use a
shut-off nozzle to prevent wasting water.

with my water? It can even be fatal, especially for the
young and the elderly.
Even though your water may appear to be fine, there are many possible contaminants that you
can’t taste, see, or smell. Here are a few possible contaminants:
Total Coliforms Coliforms are bacteria that live in the intestines of humans and animals
and in the soil. They are used as indicators of the possible presence of harmful bacteria.
A total coliforms count of less than or equal to 10 indicates satisfactory drinking water.
A total coliform count greater than 10 is a strong indication that disease-causing
microorganisms may be present in your water supply. You should not drink the water
until it is properly treated.
Escherichia coli E.coli are coliforms that live only in the intestines
of humans and animals. They are great indicators of the possible
presence of harmful bacteria. If any E. coli are found in your well
water, you should not drink the water until it is properly treated.
Hardness Hardness in well water is due mainly to naturally
occurring calcium and magnesium particles. Drinking hard water is
not a health hazard. However, it will cause scaling (a buildup of minerals) on utilities
and surfaces. Hard water is also very difficult to lather, causing overuse of soap and
detergent.
Well Aware A Guide For Well Owners 21
24. Water Quality
Metals and Minerals Many different types of metals and
minerals occur naturally in the environment, and others
are derived from man-made sources. Some affect your
water’s safety, but some only affect the water’s colour
or smell. Refer to the Resources on p. 31 on how to find
more information on contaminants. Some metals and
minerals that may be found in your well water include:
• Lead • Nitrates
• Copper • Chloride
• Arsenic • Iron
• Manganese • Hydrogen Sulfide
Pesticides and Fertilizers Pesticides are man-made
chemicals that are applied to the environment in an
effort to control unwanted pests. Fertilizers are added
to soil to enhance growth of plants. Well owners should
refrain from using any chemicals in the vicinity of their
well.
Gasoline, oil, diesel fuel and other solvents Storage
tanks can leak fuel into your well, so be sure to look for
signs of leakage. Solvents such as paint thinners and
degreasers should never be used or stored around
water wells. Drinking water contaminated with these
chemicals is a health hazard.
22 Well Aware A Guide For Well Owners
25. Water Quality
Water testing
See the Resources section of this booklet
for information about testing.
Test for harmful bacteria
Bacterial contamination is the most common type of well water contamination. It is recommended
that you test your well water regularly for bacteria, including total coliforms and E.coli. Contact
your local Government Services Centre for information on free bacteria testing. Always carefully
follow the instructions included with the water sample bottle to ensure accurate results.
Testing at least twice a year for bacteria is recommended by the DOEC. If you
have a shallow well, more frequent testing is suggested.
Early spring is a good time to test your well water for bacteria. Another good time is the day after
a heavy rainfall. Melting snow and running water can carry surface contaminants into your well. If
your well water is safe under these conditions, it is more likely to be safe the rest of the year.
Test regularly even if your water seems fine, because you can’t taste, smell or see bacteria and
most other contaminants. Don’t rely on your neighbour’s test results – wells that are only a few
steps apart usually have different water quality.
Besides routine testing, you should also test:
• after major plumbing work, well repairs or major land use changes in your area.
• if you detect changes in water quality, including taste, odour,
and appearance
• if regular well users experience unexplained health problems that
may be water-related
• after flooding. (If flooding is common in your area you may want to
retrofit your well. Contact a DOEC licensed well driller.)
• after lengthy periods of non-use
Well Aware A Guide For Well Owners 23
26. Water Quality
Testing for Other Contaminants
Drinking water can also be tested for other harmful contaminants such as those mentioned in the
Possible Contaminants section. Anyone drinking well water should consider testing for metals and
minerals every two years. Your well water quality may be impaired by naturally occurring metals
and minerals, or by human activities such as landfills, road salting, septic systems and
construction.
Test your well water for metals and minerals every two years to ensure your water
is not a threat to you or your family.
Here are some suggested times to test for certain contaminants:
Test for: If you had, or detect:
• Gasoline • Fuel spill, fuel odors or a thin film of oil in your water.
• Pesticides • Past or present use of these substances near your well,
• Pesticide spill or leak, or
• Issues about possible backflow through your plumbing into your well
during mixing of pesticides and other chemicals.
•Solvents • Chemical spill in the vicinity of your well, or
• Strong chemical odor in your well water
If at any time you think there may be a problem with your well water, you should test it.
An accredited laboratory can test your well water for chemical parameters
for a fee. Contact your local Government Service Centre, or search for
“water testing” in the government blue pages of your phonebook for more
information.

If you get a serious adverse bacterial test result – or have any reason to believe
your water is dangerously contaminated – take immediate action.

sterilizing your water.
Use one, not both, of the following sterilization methods to eliminate bacterial contaminants:
Bring water to a rolling boil and then boil it for at least one
full minute. (A rolling boil is a vigorous boil that cannot be
stopped by stirring the water.) Note that although boiling is an
effective method of eliminating bacterial contamination it may
actually concentrate other types of contamination such as
chemicals, metals, and minerals.
– or –
Mix at least 2 drops of liquid household chlorine bleach to each litre of water. If
water is cloudy, use 4 drops per litre of water. Let stand for 30 minutes. There
should be a faint chlorine smell to the water. Use fresh unscented chlorine
containing 5.25 per cent sodium hypochlorite.
Refrigerate boiled or treated water in clean food-grade containers.
Bottled or sterilized water is safe for drinking. It is also recommended for food
washing and preparation, brushing teeth, bathing children, and washing dishes.
Well Aware A Guide For Well Owners 25
28. Water Quality
Shocking should not be used routinely or repeatedly. It is not a
substitute for eliminating an ongoing source of contamination or a
defect in your well.
Well disinfection
Shocking is a temporary method of disinfection used to
eliminate a one-time case of bacterial contamination.
Shocking your well is a relatively complicated exercise that
requires care and skill. You may want to engage professional
assistance. Public health offices are a source of detailed
instructions. While shocking may provide a temporary solution,
it may be more effective to boil the water you drink.
To properly shock your well, ensure you get detailed
instructions from a licensed well driller or a Public Health
Office. Information you will need to know include: Exercise care in
shocking your well.
• the correct amount of bleach to use in your well – using too much or too little can
cause problems. See Newfoundland and Labrador Government guidelines for disinfecting
dug and drilled wells.
• how to remove all filters.
• how to shut down your entire water distribution system to give your entire well water
system at least 12 hours, and no more than 24 hours, contact time with the chlorine.
Ensure chlorinated water is properly and safely drained from the system - not into the septic system!
Well water should not be consumed until you have at least three
bacteria-free tests conducted at least one week apart.
26 Well Aware A Guide For Well Owners
29. Water Quality
Eliminate the cause
If you have contaminated water, begin by considering the possible sources of
contamination. Reducing or eliminating contaminants at the source is the best place to
start.
Next, take a closer look at your well. If your well water continually exceeds drinking
water standards for bacteria, there is likely an ongoing source of bacteria affecting your
well. Are there defects in the location, construction, or maintenance of your well that
could account for the contamination? See the previous sections of this booklet. Address
any problems you identify.
If you can’t detect the cause of the problem, bring in a DOEC-licensed well driller right
away.
You may be able to save yourself a lot of money by hiring an DOEC-licensed well
driller to solve the problem instead of buying a home water treatment device.
Treatment can be beneficial – it may even be necessary in some circumstances. But
treatment should be the final option, after taking steps to reduce contaminants and
improve your well.
Well Aware A Guide For Well Owners 27
30. Water Quality
Treatment systems
Treatment systems should be selected to address your specific needs.
Consult a professional when installing a water treatment system.
For bacteria
If your water is contaminated, it is better to remove the source of the contamination than
to treat the water. However, if the problem cannot be solved at the source, a number of
water disinfection systems are available. Each system requires routine maintenance.
Refer to the owner’s manual. Regular testing of your water must continue.
Chlorinators continuously add chlorine to your water distribution system, allowing
sufficient contact time for the chlorine to kill the bacteria. These units must be checked
often to ensure that the right amount of chlorine is being added.
Ultra-violet (UV) light filters use UV light to kill bacteria, viruses, and intestinal
protozoa in pre-filtered water. A Class A system is required (NSF 55). Pre-filtration of
water is generally required for this treatment to work properly. The light needs to be
replaced regularly. Drinking water needs to be refrigerated after treatment.
Distillers boil water, then condense the vapour and collect it in another compartment.
Bacteria and minerals are removed, and some chemicals. Water should be filtered before
treatment and refrigerated afterwards. Standard is NSF 62.
Ozonators inject small amounts of ozone gas into water to kill most bacteria. Treated
drinking water should be refrigerated.

For other contaminants
WARNING: the following treatment systems
do not kill bacteria.
Reverse osmosis removes some chemicals – but not bacteria – by passing pre-filtered
water through a membrane. This process, which removes inorganic chemicals such as
chloride and nitrate, is often used in combination with carbon filters. Reverse osmosis
wastes large amounts of water, which could be a concern if water supplies are limited or
the septic tank is over-burdened. An option is to use Reverse Osmosis only for drinking
water. The standard is NSF 58, but it may be certified under NSF 42 or 53.
Activated carbon filters (pitcher style, tap-mounted, or under-sink) can improve taste
and odour and remove organic chemicals. Standard is NSF 42. Larger systems, often
used as a pre-treatment for reverse osmosis and water softening systems, remove volatile
organic compounds. Standard is NSF 53.
WARNING: bacteria can be trapped and multiply in
a carbon filter. Regular maintenance is required.
Ion exchange water softeners should remove calcium and magnesium
“hardness”, thus reducing the scaling tendency. Standard is NSF 44. Common
domestic water softeners increase the level of sodium in drinking water.
Individuals on salt-reduced diets should consult their physician if sodium levels
in their drinking water exceed 20 mg/litre.
Well Aware A Guide For Well Owners 29
32. Hiring a well driller
Always hire a DOEC-licensed driller
As set out in the Water Resources Act, a licensed well driller must be trained and certified
according to standards set by the Well Drilling Regulations. A list of well drilling companies is
available through the Newfoundland and Labrador Government website at:
www.gov.nl.ca/Env/env/waterres/Groundwater/ground_water.asp
Some tips:
• Ask to see the license. Confirm that the license
is up to date with the DOEC.
• Get more than one licensed driller to
provide you with advice, a detailed written
description of the proposed work (e.g.,
expected well depth, unit rates, extra services),
and an estimate of the total cost.
• Get references and review past work
before making a final decision. Ask the licensed
drillers the expectations of water quality
and quantity in your area and confirm this with
your neighbours.
• Get a signed agreement in writing if there are
any changes in the work and cost.
• Pay promptly when the work is completed as
described in the agreement.
• Contact the DOEC if you have any
questions or concerns about the qualifications
or work procedures of drillers.
• Keep all documents relating to your well, pump,
pumping test, and maintenance.
• Many licensed water well drillers will provide a
yearly service check for a fee.
30 Well Aware A Guide For Well Owners
33. Your water well records
A well driller must provide you with a copy of a water well record. Each well must have its own
well record. Contents include well depth, casing length, water yield test results, a geological log
that describes the soil and/or bedrock conditions, well location with GPS coordinates, water type
encountered, drilling method, pump recommendations and more.
The well record should be updated when the depth of the well is changed or the well is upgraded
or plugged and sealed.
If you don’t have a record for your existing well, you can order them from the DOEC. Well records
are entered under the name of the original well owner.
Keep your well records in a safe place, in a file with all papers relating to the well. Make copies
to give to drillers. Keep them with test results, invoices and descriptions of work completed, filter
and treatment system manuals, service records, and reference materials like this booklet.
Records should be provided to new owners on sale of the property.
