Who
Protects the Lloyd Aquifer?
The
Place
Long Island is positioned directly over sole source aquifers isolated
by salt water from the continental aquifers. These freshwater aquifers
are the only source of freshwater for Long Island’s expanding
population. All around us are ecologically important bodies of water
which also serve the recreational and shipping needs of the New
York metropolitan area. The Long Island Sound, the Great South Bay,
and the Peconic estuary are all significant for migratory birds,
spawning fish, and wetlands habitats, as well as being places of
fun and tranquility for residents and tourists.

The Problem
Beginning with its farming heritage and continuing with the spread
of suburban development, Long Island’s ground and surface
waters have been subjected to similar pollutants. First pesticides
and fertilizers seeped into the ground and out to the streams and
rivers. These chemicals have continued with suburban sprawl, and
petrochemicals, sewage, pharmaceuticals and other pollutants have
been added to the mix. Drinking water sources are becoming increasingly
polluted by nitrogen, pharmaceuticals, pesticides and other chemicals.
Isolated wells have been closed, and there is an ongoing effort
by the group Water for Long Island (including Sierra Club’s
Long Island Group) to protect the deepest protected Lloyd Aquifer
from being tapped to dilute nitrogen levels from a tainted well.
Similarly, Long Island’s rivers and bays are in serious trouble,
with some experiencing severe die-offs.
Eutrophication is an increase in chemical nutrients — compounds containing nitrogen or phosphorus — in an ecosystem, and may occur on land or in water. However, the term is often used to mean the resultant increase in the ecosystem's primary productivity (excessive plant growth and decay), and further effects including lack of oxygen and severe reductions in water quality, fish, and other animal populations.

Non-point source pollution
Non-point source pollution describes the sum of the many individual
sources of pollution from households and businesses. Some of the
biggest polluters are oil, pesticides, fertilizer, and pet waste.
One pint of oil can cause an oil slick the size of a football field,
and used motor oil is the biggest source of non-point source oil
pollution. Yearly, the US spills the equivalent of 16 Exxon Valdez
spills into our waters. Overuse of lawn fertilizers contributes
as much as half of nitrogen pollution in water, and pesticides can
drift or wash away to waters where they can affect aquatic organisms
or people. Pet waste is a major reason for beach closings due to
coliform bacteria- this is a good point to make with public education.

Sewage
About 25 percent of the U.S. population relies on decentralized—or
onsite—wastewater treatment systems. In Suffolk County (most
of Nassau County is sewered), the number is much higher- in a 1990
census 70 percent of homes used septic tanks or cesspools! Around
20 percent of inspected systems are obviously failing to properly
treat waste, but the number contaminating ground and surface waters
is likely far higher. The major sewage pollutants are nitrates,
phosphates, and harmful bacteria. Nitrates in drinking water source
can cause methemoglobinemia, or blue baby syndrome, and other health
problems for pregnant women. Nitrates and phosphorus in surface
water can spur algal growth and low dissolved oxygen, which in turn
leads to die-offs. This has been seen dramatically in the Forge
River and has been attributed to a high concentration of septic
systems near the river. Harmful bacteria reaching ground water or
surface waters can cause human disease through direct or indirect
ingestion.

Pharmaceuticals- a growing problem
More people taking more prescription drugs leads to more
biologically active chemicals being passed to the wastewater and
into the ground. Traces of the most commonly used chemicals (anti-depressants,
birth control) have begun showing up in streams and wells across
the country- this can be expected to increase as wastewater from
the last decade move through the aquifers. Public education should
be used to inform people that prescription drugs should be thrown
in the garbage, not dumped down the drains.

The Solution
Since drinking water and surface water are two different but related
issues on Long Island, the solution is combined education and policy
designed to reduce the common pollutants. To improve the water,
we must go straight to the source of the problem- bad waste management
and careless use of chemicals.

What the public can do
The public can make conscious decisions to reduce individual contribution,
and become a messenger of environmental solutions. They can practice
water conservation, maintain and inspect septic systems regularly,
and dispose of household chemical and pet waste at a STOP collection
site or in the garbage as appropriate. If cesspools fail, they should
be replaced with a well planned septic system (though this is not
legally required), and if the home is in a sensitive (high water
table) area, homeowners should look into more advanced treatment
options. Residents can reduce the number and amount of chemicals
you use in and around the house. Buried oil tanks- abandoned or
not, should be removed. If they begin to leak, remediation can grow
into the many thousands of dollars, so it is best to remove them
as soon as possible. The public can act as environmental messengers
to share knowledge of the problems and solutions, and thereby reduce
the cost to government of fixing our mistakes.

What government can do
Leaders in government need to develop a unified plan to protect
ground and surface water, including working together on standards,
regulations, oversight, and public education. Both Nassau and Suffolk
Counties should protect special groundwater recharge areas, which
are being developed regularly. Reducing sewage and other pollutants
closest to surface water, in high building density areas, and in
groundwater recharge areas should be an immediate priority while
longer term general solutions are planned out. More intensive treatment
systems can be added to septic systems for about $6,000 each that
remove 60-80% of nitrogen and can be used in high water table areas
(although in high water table areas the phosphate treatment of a
regular septic system is lost, so perhaps a holding tank is most
appropriate there), and sewering should be used for super-high density
downtown areas. All levels of government from national to local
can and should work together to generate funding to immediately
update sewage treatment in these especially sensitive locations.
Some municipalities are beginning to address the causes of water
pollution, especially non-point source pollution from road runoff,
but real solutions will take real commitment from the public and
from officials. A draft water resources management plan should be
coming from Suffolk County this fall.

What the Sierra Club can do
To address surface water, the Long Island group will build on our
current efforts to protect estuary health. We recently donated a
storm water filtration basin to a village to reduce harmful non-point
source runoff and led a conservation outing addressing estuary health.
We have held two community meetings on ground (2006) and surface
water (2007). We are active members of the LI Water group, which
meets monthly to work to on these issues. We are also currently
supporting two measures that will protect water by preserving open
space. One is a ¼ cent sales tax to fund Suffolk County open
space, the other is a community preservation fund in Brookhaven
township, which would utilize a real estate transfer tax to fund
open space purchases. The information included here is being published
in the Fall LI Group newsletter in the form of an article, along
with information on keeping a septic system fully functioning. These
steps can be expanded with the development of educational materials
for the classroom and for targeted distribution to the public. With
the help of volunteers, we can be a more active participant in public
decisions affecting our water, by commenting on and (this is really
a major goal) contributing to formation of public policy. Additionally,
Long Island’s rivers could be aided by the River Sentinels
program, in which volunteers track the health of rivers by gathering
samples and submitting them for analysis, paid for by the Sierra
Club. Overall, a more focused campaign plan is needed, and I hope
that the national water committee can help us with this.

The
Lloyd Aquifer
MAJOR
UPDATE!
We
are very pleased to announce that DEC Commissioner Grannis ruled
in favor of the Sierra Club and other groups’ position, and
denied the well permit to SCWA. Congratulations are in order for
all those who testified in opposition to SCWA’s application
in DEC court, and to Sarah Meyland for coordinating the intensive
court proceedings to oppose the application. For more information
about the Lloyd and the reasons to protect it, see below.
Who
Protects the Lloyd Aquifer?
The
Sierra Club, LI Group, along with a number of other groups and individuals,
is protecting the oldest and most pristine aquifer formation beneath
Long Island, the Lloyd Aquifer. The Lloyd formation is over 50 million
years old and the water in it is as much as 8,000 years old, nearly
as old as the last ice age.
Because
the Lloyd Aquifer is at the bottom of the sequence of aquifer layers
located beneath Long Island, it usually takes decades for water
to reach and replenish it. And it takes thousands of years for water
in the Lloyd to slowly migrate to the coastline where it discharges
into the Atlantic Ocean or Long Island Sound.
For
the past 20 years, the Lloyd Aquifer has been protected by a state-imposed
“moratorium” on drilling any new wells into it unless
they are for use by “coastal communities.” Coastal communities
are areas vulnerable to saltwater intrusion. When sea water moves
inland, taking the place of fresh water in the aquifers, this is
saltwater intrusion. By this process, water can eventually become
too salty to drink and the affected community must find a new source
of water. The chloride content of sea water is about 19,000 parts
per million (ppm). It only takes 250 ppm of chlorides to make water
undrinkable under the New York State drinking water standards.
Taking
too much fresh water out of the groundwater system by over-pumping
can cause saltwater intrusion. Without the force of the fresh water
to hold out the ocean, it moves into the aquifer contaminating it.
As the smallest of the three primary aquifers, the Lloyd contains
only 9% of the total freshwater on Long Island. Significant pumping
can easily produce saltwater intrusion in the Lloyd.
For
over 20 years, it has been accepted policy that the Lloyd must be
protected and preserved for those coastal areas that need it now
or in the future. However, the Suffolk County Water Authority (SCWA)
is trying to be the first non-coastal community in decades to gain
access to the pristine Lloyd waters.
A
SCWA well field in the East Northport area of Huntington is seriously
polluted by a number of chemicals including nitrates, volatile organic
compounds (VOCs) and perchlorates. Nitrate levels are high because
too much raw sewage from septic tanks is being discharged into the
ground. Nitrates may cause blue-baby syndrome. VOCs are those toxic
chemicals you read so much about. Many are potential carcinogens.
They come from spills, industrial discharges and consumer products
such as paint thinner or nail polish. Perchlorate is officially
identified as a derivative of rocket fuel. Scientists speculate
it may also be produced by the breakdown of certain fertilizer products.
Perchlorates are linked to thyroid disease and possibly prostate
cancer.
At
the East Northport well field site, near the VA Hospital, SCWA wants
to drill a new Lloyd well. From that well, they propose to take
very pure water and “blend” it with water from a closed
well high in Nitrates. By dilution, the Nitrate level can be dropped
below the drinking water standard and then the water is sold back
to the customers.
The
Sierra Club and others have opposed the SCWA plan. In our view,
SCWA is not faced with an emergency or extreme hardship - - the
legal standard that would allow them to use the Lloyd. If SCWA were
to succeed in their efforts, it would likely open the door for more
water suppliers to enter and ultimately over-pump this fragile water
source. This would ruin the oldest and cleanest water remaining
on Long Island. The old adage, the “solution to pollution
is dilution” is not the answer in this case. The answer is
to honor the Lloyd Moratorium and save the Lloyd for those who truly
need it.
