Yarmouth Water is committed to providing Yarmouth residents and visitors with highest quality drinking water 24 hours a day 365 days a year. To ensure we deliver this quality product Yarmouth Water has made significant investments in water treatment facilities, water quality monitoring, water source protection, and distribution systems. We are pleased to be reporting the results of our 2001 water testing directly to you the consumer.
Each year the Yarmouth Water conducts more than
1,000 water quality tests on samples taken throughout the Town of
Yarmouth. These tests confirmed that
your tap water meets all state and federal drinking water quality standards,
and that your water is safe to drink.
We will be mailing a report to you each year with information about the
quality of your drinking water.
Within the Town of Yarmouth there are 24 groundwater wells that draw water from 2 aquifers or lens. The Sagamore Lens which supplies most of the water for Yarmouth, and the Monomoy Lens, which supplies the remainder to a lesser extent. Your tap water may come from either of these sources depending upon where you live and the time of year. Below is a listing of the locations of our water systems well sites. PS = Pumping stations.
PS 1 main - 102 Union Street PS 1,2,3,14,20,24 - Higgins Crowell Road PS 4,5 - Long Pond Drive PS 6,7,8,9 North Main St.
PS 10 - Forest Road PS 11 - Kristin Path PS 13,18,19 - Chickadee Lane PS 17 - Horse Pond
PS 15,16,21,22 - North Dennis Road PS 23 - Midtech Drive
Even
though Yarmouth Water uses basic treatment techniques along with some of the
most advanced equipment available, it is still necessary to start with the
highest quality water sources. That is
why Yarmouth Water owns and protects over 963 acres of land surrounding well
fields and aquifer recharge areas. We
also inspect these areas regularly for any condition that could adversely
affect the quality of the water. In
addition our staff reviews and comments on local land development plans near
our well fields that could impact water quality. A complete list of all the contaminants tested for is available
at our offices, located at 99 Buck Island Road W. Yarmouth, 8:30 am – 4:30pm.
In
addition to water quality test results, this report will provide information

The Safe Drinking Water Act (SDWA) was signed into law on December 16, 1974. The purpose of the law is to assure that the nation’s water supply systems serving the public meet minimum national standards for the protection of public health.
As
amended and re-authorized by the 1996 U.S. Congress the SDWA requires that all
public water systems with piped water for human consumption with at least 15
service connections or a system that regularly serves at least 25 individuals,
must provide such consumers with an “Annual Drinking Water Quality Report”.
The
SDWA directed the U.S. Environmental Protection Agency (EPA) to establish
national drinking water standards.
These standards limit the amount of certain contaminants provided by
public water. The Food and Drug
Administration (FDA) regulations establish limits for contaminants in bottled
water. More information about contaminants and potential health effects can be
obtained by calling the EPA Safe Drinking Water Hotline (800-426-4791).
The table below shows only the substances
that were detected in the Yarmouth Water in 2001. Not all substances were detected at each of the 24 well fields.
Regulated Contaminants |
||||||||
|
The
“Level Found” column represents an average of sample result data collected
during the Water Quality Parameters (WQP) calendar year beginning January 1st,
2001 through December 31st, 2001.
The “Range of Detection” column represents a range of individual
sample results, from the lowest to the highest that were detected during the
WQP calendar year. If a date appears
in the “Date of Sample” column, the State of Massachusetts DEP requires monitoring
for this contamination less than once a year because the concentrations found
previously do not frequently change.
If no date appears in the column, monitoring for that contaminant was
conducted during the annual WQP calendar year. |

action level, which the EPA defines as the equation: (number of samples) x
(0.9) = the sample corresponding to the 90th percentile. *** Number of sites above action level. This report was prepared by Bob Wright,
Plant Supervisor of the Yarmouth Water Department. For more information, call the Yarmouth Water at 508-771-7921 ext

Drinking
water, including bottled water, may reasonably be expected to contain at least
small amounts of some contaminants. The
presence of contaminants does not necessarily indicate that the water poses a
health risk. More information about
contaminants and potential health effects can be obtained by calling the EPA’s
Safe Drinking Water Hotline (800-426-4791).
Sources
of Drinking Water (both tap and bottled water) in rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As
water travels over the surface of the land or through the ground, it dissolves
naturally-occurring minerals and, in some cases, radioactive material, and can
pick up substances resulting from the presences of animals or from humans.
(TT) Treatment Technique
applied to Your Water
The
Yarmouth Water Department currently uses two distinct treatment techniques
through its service area. The first
treatment technique is for the purpose of adjusting the ph of your water. This is accomplished by adding Potassium
Hydroxide to achieve a ph range of 6.8 to 7.2.
The second treatment technique is for the purpose of sequestering Iron
and Manganese, this is accomplished by adding Sodium Hexametaphosphate.
Vulnerable Population
Some
people may be more vulnerable to contaminants in drinking water than the
general population. Immuno-compromised
persons such as persons with cancer undergoing chemotherapy, persons who have
undergone organ transplants, people with HIV/AIDS or other immune system
disorders, some elderly and infants can be particularly at risk from
infections. These people should seek
advice from their health care providers.
EPA/CDC guidelines on appropriate means to lessen the risk of infection
by Cryptosporidium and other microbial contaminants are available from the Safe
Drinking Water Hotline (800-426-4791).
Consumer
Educational Statements
Nitrate. Infants below the age of six months who drink water
containing nitrate in excess of the MCL could become seriously ill, and, if
untreated, may die. Symptoms include
shortness of breath and blue baby syndrome.
Nitrate
in drinking water at levels above 10 ppm is a health risk for infants of less
than six months of age. High nitrate levels in drinking water can cause blue
baby syndrome. Nitrate levels may rise quickly for short periods of time
because of rainfall or agricultural activity. If you are caring for an infant,
you should ask for advise from your health care provider.
Lead. Infants and children who drink
water containing lead in excess of the action level could experience delays in
their physical or mental development. Children could show slight deficits in
attention span and learning abilities.
Adults who drink this water over many years could develop kidney
problems or high blood pressure. It is
possible that lead levels at your home may be higher than at other homes in the
community as a result of materials used in your home's plumbing. If you are
concerned about elevated lead levels in your home's water, you may wish to have
your water tested. Additionally, flushing your tap for 30 seconds to two
minutes before using tap water to reduce lead content. Additional information
is available from the Safe Drinking Water Hotline, 1-800-426-4791
Unregulated Contaminants
Unregulated
contaminants are those for which the EPA has not established drinking water
standards. The purpose of unregulated contaminants
monitoring is to assist the EPA in determining the occurrence of unregulated
contaminants in drinking water and whether future regulation is warranted.
Definitions You Need to Know
Microbial contaminants, such as viruses and
bacteria, from sewage treatment plants, septic systems, agricultural livestock
operations and wildlife.
Total Coliform Bacteria, Coliforms are bacteria that
are naturally present in the environment and are used as an indicator that
other, potentially-harmful, bacteria may be present.
Fecal Coliform and e. Coli, Fecal coliforms and e. Coli
are bacteria whose presence indicates that the water may be contaminated with
human or animal waste. Microbes in
these wastes can cause short-term effects, such as diarrhea, cramps, nausea,
headaches, or other symptoms. They may
pose a special health risk for infants, young children, and people with
severely–compromised immune systems.
Inorganic contaminants, such as salts and metals,
which can be naturally – occurring or resulting from urban storm-water runoff,
industrial or domestic waste water discharges, oil and gas production, mining
or farming.
Organic Chemical
contaminants,
include synthetic and volatile organic chemicals that are by-products of
industrial processes and petroleum production, and can also come from gas
stations, urban stormwater runoff, and septic systems.
Radioactive contaminants, can be naturally-occurring
or be the result of oil and gas production, and mining activities.
pCi/l, picocuries per liter. A measure of radioactivity.
MCL, The “Maximum contaminant
level” is the highest level of a contaminant that is allowed in drinking
water. MCLs are set as close to the
MCLGs as feasible using the best available treatment technology.
MCLG, “The Maximum contaminant
level goal” is the level of a contaminant in drinking water below which there
is no known or expected risk to health.
MCLGs allow for a margin of safety.
ppm, “Parts per Million” which is
also the same as saying Milligrams per liter (mg/l). One part per million corresponds to a single penny in $10,000.00
or one minute in a two year period.
ppb, “Parts per Billion” which is
the same as saying Micrograms per liter.
One part per billion corresponds to a single penny in $10,000,000.00 or
one minute in a 2,000 year period.
AL, Action level, the
concentration of a contaminant, which if exceeded, triggers treatment or other
requirements that a water system must follow.
TT, “Treatment Technique”
A required process intended to reduce the level of a containments in drinking
water.
Variances and Exceptions
Yarmouth
Water was granted a renewal of waivers December 18,1998 by the Massachusetts
Department of Environmental Protection, Division of Water Supply Office, not
requiring our system to monitor for synthetic organic compounds (SOC’s). Previous years of testing have indicated
that these substances do not occur in our source water. Yarmouth Water however does test for these
contaminants for our historical database and will continue sampling
annually. A complete list of all the
contaminants tested for, is available at our offices, located at 99 Buck Island
Road W. Yarmouth, 8:30 am – 4:30pm. 771-7921
