Household water treatment in Poolesville, Maryland.

The Town of Poolesville relies entirely on groundwater from 10 wells drilled 285 to 800 feet into the New Oxford Formation, and its 2025 report lists nitrate at a highest level of 8.52 ppm against a limit of 10.

Ten wells under one town

Poolesville's 2025 report puts chlorine at 0.7 ppm and trihalomethanes at a highest level of 20 ppb, and the town found no lead service lines in its inventory. A Poolesville assessment starts from that report and from what shows up on your fixtures.

The way we work does not change from house to house. We look up the public data on your water, tell you what your home actually needs, and put it in for one all-in price.
