Your Water is Safe to Drink

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 2000 water testing directly to you the consumer.

 

Water Quality Testing

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.

Your Drinking Water Source

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           

 

Protecting Source Waters

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.

Water Quality Summary

The table below shows only the substances that were detected in the Yarmouth Water in 2000.  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, 2000 through December 31st, 2000.  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.

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 Substances Found in Your Tap Water

Drinking water, including bottled water, may be reasonably expected to contain at least some small amounts of certain substances that the EPA calls “contaminants”.  The presence of these substances does not necessarily indicate that the water poses a health risk.  For example, naturally occurring dissolved minerals are commonly found in well water.  More information about substances found in your tap water and their potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791)

 

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/Centers for Disease Control and Prevention (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. 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 young children are typically more vulnerable to lead in drinking water than the general population. 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.

 

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
