Common Pollutants

Pollutants enter our water systems through various means, many of which come from common household substances.

Coliform Bacteria

Coliform bacteria are rod shaped bacteria connected with the colon of warm-blooded animals. Coliform bacteria are useful indicator organisms because their presence in food or water indicate poor sanitary conditions.

Heavy Metals

Heavy metals are elements found in water that can be detrimental to human health. Learn more about the associated health risks and treatment options.


Testing Your Drinking Water

There are many options for testing the quality of your drinking water. Water in public systems is tested every year and data is compiled into a Consumer Confidence Report, which discloses any contaminants, possible health effects, and information about the water's source. These are completed by local health departments and water districts. Private systems do not fall under the same regulations, so it is up to the owner to test the water.

Protect Your Well

Approximately 15% of Americans get their drinking water from private wells. These wells, which tap into local groundwater, are designed to provide clean, safe drinking water. Improperly constructed, or poorly maintained wells, can create a pathway for fertilizers, bacteria, pesticides or other materials to enter the water supply.


Water Treatment

There are many options to improve the quality of your drinking water whether you are part of a public or private system. These include the use of water filters and faucet aerators, as well as routine maintenance of household plumbing and water heaters.
