Is my tap water safe to drink in Connecticut?

It depends on your ZIP code and who lives in your home. CheckYourTap analyzes 120+ contaminants in your local water supply and shows which ones exceed health guidelines — not just legal limits. Many contaminants are legal but still pose health risks, especially for babies, pregnant women, elderly, and pets.

What contaminants are in Connecticut tap water?

Connecticut tap water commonly contains disinfection byproducts (haloacetic acids, trihalomethanes), lead from aging pipes, PFAS (forever chemicals), nitrates, arsenic, and radionuclides like radium. The specific contaminants and levels vary by water system — enter your ZIP code to see your local results.

How does CheckYourTap differ from EWG or other water quality databases?

CheckYourTap is the only water quality report personalized for your household composition. Tell us who lives in your home — babies, children, pregnant women, elderly, dogs, or cats — and we calculate adjusted safe levels for each person. A contaminant safe for adults may exceed guidelines for infants by 8x or more.

Is CheckYourTap free?

Yes, CheckYourTap is completely free. Enter your Connecticut ZIP code and household members to get a personalized water quality report with health risk assessments for 120+ contaminants.

Does CheckYourTap cover well water in Connecticut?

Yes. CheckYourTap covers both city water (public water systems) and private well water in Connecticut. Well water reports use USGS groundwater data and include geology-based risk factors for arsenic, uranium, and radon specific to your area.
