What Makes Clinton's Water Unique?
Local geology and source profile
Clinton, Maryland, an unincorporated community in Prince George's County — a major south Prince George's County community (Clinton is one of the largest unincorporated communities in Prince George's County — a major suburban community in the southern DC suburban corridor), a diverse Prince George's County community with a significant African-American professional population (Prince George's County has one of the highest concentrations of affluent African-American households in the United States, and Clinton is a significant part of that demographic pattern), adjacent to Andrews Air Force Base (Joint Base Andrews — home of Air Force One and the presidential aircraft fleet, a major military base in the Clinton–Camp Springs corridor), and a primarily residential community in the I-5 south Prince George's County corridor — draws its municipal water supply via the WSSC Water. Water hardness in Clinton measures 178 mg/L — classified as hard.
Clinton's hard supply reflects the WSSC supply characteristics and the south Prince George's County distribution zone. The WSSC Patuxent River watershed (Triadelphia and Rocky Gorge Reservoirs) drains the Maryland Piedmont and the Cambrian Cockeysville Marble (calcareous marble of Baltimore–Howard Counties). WSSC distributes through the south Prince George's County Clinton zone (a mix of 1960s–1980s suburban mains serving the Clinton planned development area), producing the hard 178 mg/L.
At 178 mg/L, Clinton residents encounter regular hard water scale. Monthly descaling with citric acid solution is recommended. WSSC Water consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply via the Washington Suburban Sanitary Commission (WSSC Water) — the Prince George's County south Maryland DC suburban corridor (WSSC Patuxent River Triadelphia and Rocky Gorge Reservoirs — the Maryland Piedmont calcareous-moderate crystalline supply; WSSC south distribution to Clinton Prince George's zone); hard supply at 178 mg/L in Prince George's County.
