Forestville Water Hardness & Quality Report (2026)

Forestville, located in Prince George's County, Maryland, gets its drinking water from WSSC Water, a utility serving more than 1.8 million people across Montgomery and Prince George's counties. The main sources are the Patuxent River and Potomac River, with water filtered at the Patuxent and Potomac Water Filtration Plants. Groundwater from confined aquifers is also used to meet high demand. This suburban community, southeast of Washington, D.C., receives its supply originating from the Patuxent River watershed, which spans both the Piedmont and Coastal Plain physiographic provinces.

Geologically, the water supply is influenced by formations like the Triassic New Oxford Formation conglomerates and the Cretaceous Arundel Clay, found near the river intakes. The Potomac Group aquifers, part of the Atlantic Coastal Plain, contain quartz sands and calcareous clays. Dissolution of minerals from these geological features, particularly limestone and dolomite in the Coastal Plain, gives the water its hard character and elevated dissolved solids, a common trait for mid-Atlantic river systems.

Homeowners in Forestville will likely notice scale buildup in appliances like water heaters, dishwashers, and washing machines, which can decrease their efficiency by up to 30% over time. Faucet aerators and coffee makers may require cleaning within a couple of years. To manage these effects, regular descaling with vinegar and flushing water heaters annually are recommended. Installing a water softener is a good idea for households that do a lot of laundry or use appliances frequently, as it can extend their lifespan and make soaps and detergents more effective. WSSC Water maintains a pH between 7.2-8.0, well within EPA standards.
