Start with the right water supplier

A ZIP code or city name cannot reliably identify your water supplier. Check the name on your water bill, or ask your landlord or utility. You do not need to upload a bill or share an account number.

Our first verified reporting pilot covers Cambridge Water Department in Massachusetts. Other locations can request help, but we will not substitute the nearest city's results. Private wells need their own testing.

What happens next

We record your request, check the supplier and source evidence, and prepare a report or ask for missing details. A request confirmation is not a delivered report. New findings or conflicting information require review.

Urgent water problem?

We do not monitor advisories in real time. Contact your water supplier or local health department now and follow the instructions for your address.
