Is your Connecticut tap water safe? It depends on the records associated with your ZIP and who lives in your home. CheckYourTap prioritizes health-protective guidance from sources such as EWG and OEHHA while showing EPA limits as legal context. A ZIP report is not a tap test, so property-level decisions still require utility confirmation or a certified sample.
Reading this inside ChatGPT or Claude?
This page can explain the general science about your Connecticut tap water, but it cannot identify what is at a specific tap or property. You can get ZIP-level context two ways:
- Inside the chat: ask your assistant to “check my tap water with CheckYourTap”. Our connector returns available public-system or regional monitoring records associated with your ZIP. It does not identify your serving utility or test your tap, well, or property. The current connector is read-only and does not email reports or submit contact information.
- On the web: open CheckYourTap.com and enter your ZIP code for a free ZIP-level report.

Arsenic and Uranium in CT Wells by Region and Bedrock
USGS and CT DPH tested more than 2,000 Connecticut wells for arsenic and uranium. The rock units with the highest exceedance rates, the towns where they are mapped, and why only a test of your own well answers the question.
Haddam CT Well Water Testing: Bedrock, Arsenic, Uranium
Haddam is mostly Monson Gneiss, with Hebron Gneiss and the Middletown Formation. USGS found no arsenic exceedances in Monson Gneiss samples but uranium above the limit in 8.5%, and 25% in the lower Middletown Formation. What Haddam well owners should test.
Newtown CT Well Water Testing: Bedrock, Arsenic, Uranium
More than half of Newtown sits on the Brookfield Gneiss, where USGS found 12.8% of statewide well samples above the uranium limit and 5.1% above the arsenic limit. What the public record shows and what Newtown well owners should test.
