Is your Connecticut tap water safe? It depends on your ZIP code and who lives in your home. Public water usually meets federal legal limits, but many contaminants — lead, PFAS, nitrate, and disinfection byproducts — are often present at levels above the stricter health guidelines that matter most for infants, pregnancy, and older adults. CheckYourTap checks every contaminant your water system tested for, for your exact ZIP and household, free, and tells you what to do about it.

Can a Spill Contaminate City Tap Water? Honestly

Public water is treated and monitored, so a nearby spill rarely reaches your tap. Two narrow pathways are real; vapor intrusion (indoor air) isn't one of them.

Cats and Connecticut Water: 4 Things Owners Miss

Cats are not small dogs when it comes to water. A missing liver enzyme, unusually fragile blood, and slow chemical clearance make them the most water-sensitive pet in your house. Here's what that means in Connecticut.

Frequently Asked Questions

Is my tap water safe to drink in Connecticut?▾

It depends on your ZIP code and who lives in your home. CheckYourTap checks every contaminant your water system tested for, up to 119 depending on your ZIP, and shows which ones exceed health guidelines rather than 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?▾

Most water-quality databases give you one number per contaminant. CheckYourTap adjusts the health guideline for who actually lives in your home. Tell us who lives in your home, whether that is babies, children, pregnant women, older adults, dogs or cats, and we show adjusted safe levels for each. A contaminant that is legally compliant and fine for an adult can still exceed the health guideline that matters for an infant, because a baby drinks far more water per pound of body weight than you do.

Is CheckYourTap free?▾

Yes, CheckYourTap is completely free. Enter your Connecticut ZIP code and household members to get a personalized water quality report covering every contaminant your water system tested for.

Does CheckYourTap cover well water in Connecticut?▾

Yes. CheckYourTap covers both city water (public water systems) and well water in Connecticut. Well reports draw on groundwater wells in the USGS and state sampling record near your ZIP, plus geology-based risk factors for arsenic, uranium, and radon. That is context for your area, not a test of your own well. Only a lab test of your water tells you what is in your well.
