Potable Water Program

The Potable Water Program is a program of the Department of Energy and Environmental Protection (DEEP). DEEP's page, last modified July 24, 2026, says the program assists individuals whose private or public drinking water supply wells may be at risk of becoming contaminated, or have become contaminated, as a result of human activity.

In a Phase I ESA

ASTM E1527-21 does not name drinking water well records among its standard sources. DEEP ties wells to site work in two of its other programs, which is why this page is here: its Significant Environmental Hazards page lists detected pollution in a drinking water supply well as a reportable condition, and its Significant Existing Releases page lists drinking water well contamination first among its categories. See Significant Environmental Hazards and the Release-Based Cleanup Program.

• DEEP can investigate complaints. DEEP says the Remediation Division can investigate complaints about impacts to drinking water supplies under section 22a-471 of the Connecticut General Statutes. If the source of the pollution can be determined, it says the Commissioner may issue an order requiring the polluter to provide potable water, short term and long term, which may include connecting to a public water system.
• Natural contaminants are outside it. DEEP says the program does not address naturally occurring contaminants in drinking water and points those cases to the Department of Public Health's Private Well Program and the local health department.
• Help for owners is limited. DEEP says it is generally unable to provide bottled water or to install and maintain treatment systems at residential locations or at elementary or secondary schools with polluted wells. It says limited funding is available for homes in a Remediation Division PFAS investigation area.
• Many households use private wells. DEEP says approximately 23% of Connecticut's population relies on private wells as their source of drinking water.

DEEP links a Water Supply Well Receptor Guidance Document, and its Significant Environmental Hazards page strongly recommends that guidance when determining the presence of nearby drinking water receptors.

Where to look a site up

• The page names no DEEP list of wells or of well complaints.
• Under Department of Consumer Protection resources, DEEP's page names a well drilling reports collection that it says includes reports from 1970 to the present. The link's address is not on a ct.gov site, so it is named here and not linked.
• For well pollution from human activity other than PFAS, DEEP says to contact the Remediation Division District Supervisor for the town the well is in, and links its Remediation Division Contacts page. For PFAS it gives DEEP.PFAS@ct.gov. For other questions about man-made contaminants in drinking water it gives DEEP.PotableWater@ct.gov.

Getting the file

The pages read do not describe a file for a well complaint or say how to request one. Ask the Remediation Division, and see the Environmental Quality Records Center page for DEEP's records route.
