Connecticut Water Quality Facts and Drinking Water Problems

The water in Connecticut comes from a complex system of streams, rivers, and reservoirs across the state. In addition, many residents get their water from private wells. The U.S. Environmental Protection Agency does not regulate private wells in Connecticut, so it is important for homeowners with private wells to get their water tested annually.

Many cities throughout Connecticut run into water quality problems with hard water, water that has a higher-than-usual metal content, and poor-quality water that causes lime or white scale buildup.

Different cities in Connecticut can experience different water challenges — so the quality of water across the state can vary greatly. Learn more about the water where you live:
