Every supported contaminant record, checked against health-protective guidance, with source-bound household context for babies, pregnancy, older adults, and pets.

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.

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 the supported records for water systems associated with your ZIP and shows how reported levels compare with health-protective guidance. Because a ZIP is not a property test, confirm your serving utility and test your own tap when a property-level answer matters.
What contaminants are in Connecticut tap water?
Connecticut water records include disinfection byproducts, lead, PFAS, nitrates, arsenic, and radionuclides such as uranium and radium. The specific contaminants, units, dates, and reporting systems vary by ZIP; enter yours to review the retained source records.
How does CheckYourTap differ from EWG or other water quality databases?
Most water-quality databases give you one number per contaminant. CheckYourTap keeps the source measurement and unit visible, prioritizes exact EWG/OEHHA health references for selected people, and adds source-backed veterinary context for selected pets. A human value is never relabeled as pet-safe, and EPA limits remain legal context rather than CheckYourTap's definition of healthy.
Is CheckYourTap free?
Yes. Enter a Connecticut ZIP code and household members to get a free report of the supported water records associated with the ZIP. No signup is required.
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.
