Household water treatment in Clarksburg, Maryland.

Clarksburg homes on WSSC Water receive Potomac River water, and WSSC's 2025 report lists nitrate in that water at a highest level of 1.6 mg/L against a limit of 10.

Sulfate, nitrate and hardness, on record

Sulfate in Potomac plant tap water averaged 52.5 mg/L in 2025, and hardness averaged 154 mg/L. WSSC adds orthophosphate to coat the inside of pipes, and a Clarksburg assessment reads those figures alongside what you see on your fixtures.
