Kittery Water District

17 State Rd., Kittery, ME  03904

April 30, 2008

 

MISSION STATEMENT

Kittery Water District recognizes that water and watersheds must be preserved, conserved and protected; that an adequate supply of clean water is a basic human right; that water is a public trust, to be guarded by all levels of government acting as an equal partner with the public; and that the best advocates for water are local communities and citizens.  The District strives to maintain stable water rates for domestic and municipal purposes.

   The 10^th annual water quality report to all customers is in accordance with the 1996 Safe Drinking Water Act (SDWA) and provides general information regarding District activities. During 2007, drinking water produced by the Kittery Water District (KWD), met or exceeded all federal and state health safety requirements.

DISTRICT ACTIVITIES IN 2007

• Produced over nine hundred twelve million (912,000,000) gallons of water to the homes and businesses of Kittery, Kittery Point, parts of Eliot, the Portsmouth Naval Shipyard, and a portion of York.
• Replaced 2,596 feet of undersized, cast iron piping along Route One (North). 
• Installed a water main and fire hydrants on Lewis Road to service Durgin Pines. 
• Installed 420 feet of water main on Post Office Drive, Eliot. 
• Replaced 600 feet of water main on Cross Street, Eliot, to increase pressure and fire protection flow rates.
• Installed energy efficient windows and replaced the 50 year old boiler at the Francis L. Hatch Filtration Plant.
• With the assistance of Federal Emergency Management Agency (FEMA) disaster relief funds, rebuilt the Boulter Pond Reservoir spillway. The spillway was damaged in the 2006 Mother’s Day Storm.
• Replaced the control valves and operating mechanisms for the Boulter Pond Dam. The new equipment improves operational reliability when drawing water from the reservoir.
• Logged over 400 hours of watershed protection patrols.
• Janah Lane Subdivision, Kittery Point, installed 1,022 feet of water main and one private fire hydrant.
• Cole Brown Estates, Eliot, installed 2,516 feet of water main and two private fire hydrants.

   KWD strives to maintain a well trained, professional organization.  It is the intent of the District to be in the forefront of technology development and regulatory changes which will affect water treatment processes. The District maintains active participation in National and State Water Works professional organizations. These organizations provide a valuable resource for technical, trade skills, and safety training. Our labor force and management undergo continual training to improve our way of doing business.

REGIONALIZATION AND INTERCONNECTS

   In this difficult economic climate, utilities are under increasing pressure to lower costs and find efficiencies.  KWD has played an active role in regionalizing with surrounding Water Districts to work cooperatively on issues of mutual interest and developing shared services.  It is believed that by working together, the quality of the services will improve and costs will be lowered. That is good for our customers.

• In 2003, Kittery, York and South Berwick Water Districts regionalized.
• In 2003, York and Kennebunk & Wells Water Districts installed an emergency water main interconnect between the Districts.
• In 2004, Biddeford & Saco, Kennebunk, Kennebunkport & Wells, Kittery, Sanford, Portland, South Berwick and York Water Districts regionalized.
• In 2005, York and Kittery Water Districts installed an emergency interconnect between the Districts.
• Through interconnects, water can be transferred between Biddeford & Saco, Kennebunk & Wells, Kittery and York Water Districts.

   Cost savings realized to date have been through bulk chemical purchases, sharing of training facilities and instructors, borrowing of equipment, service contracts and mutual aid agreements.

DEFINITIONS OF TESTING TERMINOLOGY

Primary standards - Quality standards designed to protect your health.

Secondary standards - Standards relating to the aesthetic qualities of

water like taste, odor and color that do not present a health risk.

ppm (Parts per million) – unit of measure

ppb (Parts per billion) or Micrograms per liter –unit of measure

pCi/L (Picocuries per liter) - Picocuries per liter is a measure of the

radioactivity in water.

NTU (Nephelometric Turbidity Unit) - Nephelometric turbidity unit is a measure of

the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.

AL (Action Level) - Concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

TT (Treatment Technique) - A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

MCL (Maximum Contaminant Level) - The “Maximum Allowed” 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 (Maximum Contaminant Level Goal) - The “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.

BDL (Below Detection Level) - The substance is lower than what the laboratory can detect.

Variance or Exemption - State or U.S. EPA permission not to meet an MCL or a treatment technique under certain conditions.

SMCL (Secondary Maximum Containment Level) - The highest level of an aesthetic water quality parameter that is allowed in drinking water.

RAA (Running Annual Average) –The average of all monthly or quarterly samples for the last year at all sample locations.

 

Additional Notes:

1) Total Coliform Bacteria: Reported as the highest monthly number of positive samples, for water systems that take < 40 samples per month.

2) Gross Alpha: Action level over 5 pCi/L requires testing for Radium.  Action level over 15 pCi/L requires testing for Radon and Uranium.

3) Lead/Copper: Action levels (AL) are measured at consumer’s tap.  90% of the tests must be equal to or below the action level.

4) Total Trihalomethanes (TTHM)/Haloacetic Acids (HAA5): TTHM and HAA5 are formed as a by-product of drinking water chlorination.  This chemical reaction occurs when chlorine combines with naturally occurring organic matter in water.

5) Turbidity: Turbidity is a measurement of cloudiness or suspended colloidal matter (silt). Excessive turbidity can cause problems with water disinfection.  All samples taken from our system were below 0.549 ntu's for rapid sand filtration media. Therefore, our water filtration system renders your finished drinking water clear and safe to drink.

IMPORTANT INFORMATION

Lead

   If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with household plumbing. KWD is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When water has been sitting in household piping for several hours, the potential for lead exposure can be minimized by flushing your tap for up to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

 MCLs

   Maximum Contaminant Levels are set at very stringent levels. A person would have to drink 2 liters of water every day at the MCL level over the course of a lifetime to have a one-in-ten thousand chance of acquiring any adverse health effect.

 Source Information

   The District obtains our water from four man-made ponds in the town of York, Maine:  Boulter Pond, Middle Pond, Upper Folly Pond and Bell Marsh Reservoir.  The watershed for these ponds has been tested for potentially harmful pathogens such as cryptosporidium, giardia, and E-Coli. None were detected. Our source water protection program prohibits all but passive recreation around the reservoirs. Frequent watershed protection patrols assure compliance with our watershed protection policies.

   As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals, radioactive material, and also substances resulting from human or animal activity. The Maine Drinking Water Program assessed public water supplies statewide in 2003 as part of the Source Water Assessment Program. The assessment considered geology and hydrology, land uses, water testing information, and the extent of land ownership or local ordinance protection to determine how likely the drinking water source is to being contaminated in the future. This evaluation reflected positively on the District’s watershed.  The assessment is available to the public upon request. For more information, contact the Drinking Water Program at 207-287-2070.

    The District’s water treatment and filtering facility is located at Boulter Pond in York. The filtration process includes the addition of alum and hydrated lime to coagulate organic materials in the raw water. As water passes through a sedimentation process, organic materials settle out. Water is filtered as it passes through a bed of washed, filtering sand. After filtering, the water is treated with sodium hypochlorite for disinfection.  Hydrated lime is added to adjust water pH.  Prior to leaving the plant, a corrosion control chemical, trade name Seaquest, is added to reduce distribution system pipe corrosion.

 Health Information

Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production and can also come from gas stations, urban runoff, and septic systems.

   Our watershed monitoring program has tested for the above contaminants.  None were detected.  Should any contaminants be introduced, our water treatment process assures that the maximum contaminant level will be below State standards for safe drinking water.

   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 water poses a health risk.

   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 about drinking water 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 (1-800-426-4791).
