What Makes Hanover's Water Unique?
Local geology and source profile
Hanover, Maryland, an unincorporated community in Anne Arundel County near Baltimore–Washington International Airport — a major BWI Corridor commercial and industrial community in the rapidly growing Anne Arundel County I-95 corridor, home of major distribution centers and commercial operations adjacent to BWI Airport, a diverse Anne Arundel County community with a strong military and defense sector presence, and a significant residential community in the Baltimore–Washington suburban overlap zone — draws its municipal water supply via the Washington Suburban Sanitary Commission (WSSC). Water hardness in Hanover measures 193 mg/L — classified as hard.
Hanover's hard supply reflects the WSSC distribution characteristics in the Anne Arundel County BWI Corridor zone and the Maryland Piedmont's calcareous geology. The WSSC Rocky Gorge and Triadelphia Reservoirs on the Patuxent River drain the Maryland Piedmont (Precambrian calcareous-moderate Baltimore Gneiss and Setters Quartzite and the Cambrian Cockeysville Marble — the significant calcareous marble formation of Baltimore–Howard–Carroll Counties). WSSC delivers this calcareous-moderate Piedmont supply to the Hanover BWI area, producing the hard 193 mg/L.
At 193 mg/L, Hanover residents face regular hard water challenges. Monthly descaling with citric acid solution is standard maintenance. WSSC consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Patuxent River (Rocky Gorge and Triadelphia Reservoirs) via the Washington Suburban Sanitary Commission (WSSC) — the Anne Arundel County northern Maryland Baltimore–Washington corridor (Precambrian calcareous-moderate Piedmont gneiss and Cambrian Cockeysville Marble — the calcareous Maryland Piedmont zone); hard supply at 193 mg/L — reflecting WSSC distribution in the Hanover BWI Corridor zone.
