What Makes Suitland-Silver Hill's Water Unique?
Local geology and source profile
Suitland-Silver Hill, Maryland, an unincorporated community in Prince George's County — a major south Prince George's County DC suburban community (Suitland-Silver Hill is a significant inner-ring Prince George's County suburb directly adjacent to the DC line, home of the US Census Bureau headquarters — one of the most important federal statistical agencies in the United States, headquartered in a major Suitland complex), home of Joint Base Andrews (the major Air Force base adjacent to Suitland — one of the most significant military installations in the Washington DC area, home of Air Force One and the primary presidential transportation base), a diverse Prince George's County community with a significant African-American federal workforce and military professional population, and a community adjacent to Oxon Hill and Capitol Heights along the southern DC suburban corridor — draws its municipal water supply via the WSSC Water. Water hardness in Suitland-Silver Hill measures 140 mg/L — classified as moderately hard.
Suitland-Silver Hill's moderate hardness reflects the WSSC supply and the south Prince George's County distribution zone. The WSSC Patuxent and Potomac River supply (the dual-source Maryland Piedmont calcareous-moderate Triadelphia, Rocky Gorge, and Potomac River supply blend) distributes to the Suitland zone via south Prince George's mains (1950s–1970s suburban development mains), producing the moderate 140 mg/L.
At 140 mg/L, Suitland residents encounter moderate scale accumulation. Monthly cleaning 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 Suitland corridor (WSSC Patuxent and Potomac River supply blend — the Prince George's County WSSC south distribution to Suitland–Silver Hill zone; moderately calcareous-moderate Maryland Piedmont–Coastal Plain transition supply); moderately hard supply at 140 mg/L in Prince George's County.
