Is Hartford, CT tap water safe?
The short answer
Metropolitan District Commission serves Hartford. In EPA’s and CDC’s records it has nothing above a health goal, and no health-based violation since 2016.
That data covers what its report lists, not everything.
Some homes in a town are on private wells or a small system of their own. The name on your water bill tells you which is yours.
