Where the water comes from

Newmarket Water Works draws water from 4 wells.

Annual water quality report

Newmarket Water Works must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by New Hampshire.
