Ground water is one of our most
critical resources. As populations, economic growth, and material
disposal problems continue to increase, the demands placed on ground
water supplies will increase accordingly. The danger and actuality
of pollution or contamination of these supplies will also increase.
People in all walks of life, from the private citizen to those in
the highest levels of government are making decisions that will have
long term significance for all of us.
More than
60% of Maine citizens (and all of Winterport's customers) rely on
groundwater for their public and private drinking water supplies.
Various land uses and activities threaten the quality of this
valuable natural resource. Once groundwater is contaminated, it is
difficult and expensive, and sometimes impossible, to clean up.
Protecting groundwater from contamination is the most effective
method to ensure abundant sources of clean drinking water. Land
development has been identified as the dominant threat to public
water supplies, and controlling land use through purchase, easement,
or ordinance is the greatest challenge facing public water systems.
What is Wellhead Protection?
Wellhead Protection is managing land uses around a well to keep
contaminants out of drinking water.
Ninety-one percent (91%) of Maine's public water suppliers use groundwater as their
source. Most of Maine's groundwater tastes good and is safe to drink
without treatment. Maine's Wellhead Protection Program helps public
water suppliers keep it that way.
Public water suppliers have at least 15 service connections or serve
25 or more people for at least 60 days per year. They include
"private" suppliers, such as variety stores or gas stations serving
coffee; mobile home parks; campgrounds; schools; restaurants;
motels; factories; and businesses, as well as municipal water
districts.
Why does Maine have a
Wellhead Protection Program?
> Safe drinking water is essential to human health.
> To keep public drinking water supplies free of contaminants.
> To avoid the high costs of groundwater clean-up.
> To comply with the federal Safe Drinking Water Act.
The Safe Drinking Water Act amendments of 1986 asked all states to
develop a program to protect the area around public water supply
wells.
Maine's unique program requires no new state mandates or funds.
It is flexible and targets education and assistance to water
suppliers whose wells are threatened. It trusts Maine citizens
will take responsibility. If they don't, federal and state
authorities may exert greater control.
How does the program work?
The Wellhead Protection Program helps public water suppliers take
four important steps:
1. Delineation - determining the area of land from which the well
draws its water.
This is the Wellhead Protection Area. For small suppliers this
will be a circle with a 300 foot radius. Large, threatened water
supplies may require a hydrogeologist to more accurately define
this area.
2. Inventory - identifying possible sources of contamination.
Public water suppliers will want to know what's going on in the
Wellhead Protection Area which could contaminate their
well. Potentially threatening activities may include manufacturing
and storage of chemicals, underground fuel storage, pesticide use,
and poorly functioning or too many septic systems.
3.Management - exercising care to prevent contaminants from
reaching the well.
Public water suppliers can work with their neighbors and town
officials to prevent contamination from existing sources and with
their town to assure that new activities that could threaten
groundwater will be appropriately located outside the Wellhead
Protection Area. Tips for managing existing threats to
ground-water will be made available.
4.Contingency - planning what to do if the
well does become contaminated.
Public water suppliers can arrange
for alternate water supplies in the event of serious contamination
to help them avoid interruption of service.
How can you help?
If you own or occupy land in a Wellhead Protection Area
You can consider how your activities may impact the public water
supply, make sure you are complying with laws that regulate your
activities, and follow management tips provided by the water
supplier. Some examples:
If you keep gasoline or fuel oil above or under ground you will
need to comply with Title 38 of state law. A good management tip
is to make sure that any spills or leaks are caught in a rainproof
container.
If you
use any solvents, for example, in dry cleaning, electronics, or
furniture stripping, you should know that Tide 38 makes it illegal
to discharge any solvents into groundwater and requires you to
report any spills or leaks immediately. You must dispose of any
solvents at licensed facilities—never flush them into a septic
or sewer system.
If you use pesticides, you must comply with Titles 7 and 22 of state
law and follow the manufacturer's label. Avoid storing, mixing, and
rinsing pesticides in the Wellhead Protection Area. Apply
fertilizers and manure according to a nutrient management budget.
If your home is in a Wellhead Protection Area, regularly maintain
and keep household chemicals out of your septic system. Find out how
you can properly dispose of wastes such as solvents, cleaning
products, paints and used motor oil.
If you are a Town Official Code Enforcement Officers can give
priority to enforcing laws and permit conditions in the Wellhead
Protection Area. Planning Boards can issue permits with conditions
that protect the well. Police and Fire officials can plan to fit
their emergency response to wellhead protection needs.
