Health Information

From the EPA

This statement is prescribed by the US Environmental Protection Agency for your information.

Sources of lead in drinking water include corrosion of household plumbing system and erosion of natural deposits. 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 such water over many years could develop kidney problems or high blood pressure.

Sources of copper in drinking water include corrosion of household plumbing system, erosion of natural deposits and leaching from wood preservatives. Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson’s Disease should consult their personal doctor.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised 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 may be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The U.S. EPA/  CDC (Centers for Disease Control and Prevention) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 800-426-4791.

Substances That Might Be in Drinking Water

To ensure that tap water is safe to drink, the U.S. EPA prescribes regulations limiting the amount of certain contaminants in water provided by public water systems. Drinking water may reasonably be expected to contain at least small amounts of some contaminants. The presence of these contaminants does not necessarily indicate that the water poses a health risk.

The sources of drinking water include 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, in some cases, radioactive material; and substances resulting from the presence of animals or from human activity.

Substances 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, or wildlife; Inorganic Contaminants, such as salts and metals, which can be naturally occurring or may 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 may also come from gas stations, urban stormwater runoff, and septic systems; Radioactive Contaminants, which can be naturally occurring or may be the result of oil and gas production and mining activities.

For more information about contaminants and potential health effects, call the Safe Drinking Water Hotline at 800-426-4791.

Lead and Drinking Water

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Although the majority of lead poisoning in children results from eating lead-based paint chips, lead in drinking water should also be considered. Lead in water primarily comes from the materials and components associated with service lines and home plumbing.

Here are the common sources of lead in household water:

Lead service pipe: The pipe that connects the water main in the street to your household plumbing. A portion of this pipe is in public space (First District Water's responsibility) and a portion is on private property (yours). A "partial" lead service pipe is where a portion of the pipe is replaced, but a portion remains in public or private property.

Lead solder: Connects pipes in home plumbing.Brass faucets, valves or fittings: Can contain up to eight percent lead.

Galvanized iron pipes: A type of household plumbing that can be a source of lead in homes that have, or had, a lead service pipe.

The Water Department is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components of each home. If you are concerned about lead in your water, you may wish to have your water tested. For assistance with lead sampling please contact Tracey Matosian at tmatosian@firstdistrictwater.org or 203-229-7273.

When your water has been sitting unused for several hours, you can minimize the potential for lead exposure by flushing your tap for two minutes before using water for drinking or cooking.

More information on lead in drinking water can be found at www.epa.gov/safewater/lead or by calling the Safe Drinking Water Hotline at 800-426-4791.
