Drinking Water Quality: The Source Protection Connection

Connecticut is fortunate to have water supplies of high quality and sufficient quantity to meet the needs of consumers throughout the state. This is not strictly a matter of geography - it is the result of effective regulations by town and federal agencies, careful planning and operations by water utilities, and responsible use by consumers.

Source water protection is an important tool for maintaining and managing our drinking water resources. Preventing pollutants from entering reservoirs and underground aquifers is the focal point of water supply source protection. We all have an important stake in maintaining a clean, safe water supply.

How Does Connecticut Law Protect Drinking Water?

  • Connecticut is one of only two states that prohibts discharge of potential disease carrying wastewaters into public drinking water supply sources.
  • Mandatory filtration and disinfection of all surface water supplies.
  • Land areas (watersheds) that drain into public water sources must be inspected annually for sources for pollution.
  • State and local regulations govern land use and development on watershed lands.
  • Strict regulations govern the sale and use of water company owned land which are critical to the protection of public water supply resources.
  • The Aquifer Protection Act requires regulation of land use activities in critical areas around public drinking water supply wells.
  • Operator certification is required for water treatment facility personnal to ensure the effective operation of water treatment facilities.

You Can Help To Protect Connecticut's Public Water Supplies

  • Don't Dump! Dispose of trash, waste motor oil, and household hazardous wastes properly. Check with your city or town hall or water company about proper disposal of these wastes or bring to a household hazardous waste collection center.
  • Use pesticides and fertilizers wisely! Follow the directions, apply only what's needed, and don't over use. When in doubt - consult an expert! Use organic fertilizers when possible
  • Report any polluting activities! If you see illegal dumping, waste discharges, chemical spills, etc. please report them immediately to the Connecticut Department of Energy and Environmental Protection (866) 337-7745
  • Use and maintain your septic system properly! Don't pour fats, grease, oils, or harmful chemicals down the drain--they can interfere with the septic tank function and may cause groundwater pollution. Have the septic tank inspected and cleaned every 2 to 3 years.
