High Quality Source List

The Department of Public Health (DPH) has produced a list of High Quality Drinking Water Sources (HQS). The HQS list designates current and future potential public water supply sources statewide that require protection to ensure that the highest quality source waters are available for human consumption. A designated list was required by Public Act (PA) 11-242, Section 59, now codified as law in Connecticut General Statutes (CGS) Section 25-33q. The list has been divided into three bookmarked sections: existing sources, future sources and interconnections. Each section is then sorted geographically by Water Utility Coordinating Committee.
