What Makes North Bel Air's Water Unique?
Local geology and source profile
North Bel Air, Maryland, an unincorporated community in Harford County — a major north Harford County community adjacent to Bel Air (Bel Air is the Harford County seat; North Bel Air is an unincorporated community in the Bel Air area — together one of the primary residential and commercial centers of Harford County), a diverse Harford County community with a significant military professional population (Harford County is home of Aberdeen Proving Ground — the US Army's primary ordnance and weapon systems testing facility, a major employer and economic anchor for Harford County), adjacent to the I-95 north Maryland corridor, and a growing Baltimore north suburban community — draws its municipal water supply via the Harford County Water and Sewer Division. Water hardness in North Bel Air measures 134 mg/L — classified as moderately hard.
North Bel Air's moderate hardness reflects the Harford County Deer Creek–Bush River watershed's calcareous-moderate Maryland Piedmont geology. The Deer Creek and Bush River watershed at North Bel Air–Harford County drains: the Precambrian–Paleozoic Maryland Piedmont (calcareous-moderate gneiss and schist); and the Cambrian Wissahickon Schist (calcareous-poor to moderate). Harford County Water and Sewer treatment produces the moderate 134 mg/L.
At 134 mg/L, North Bel Air residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Harford County Water and Sewer Division consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Bush River and Deer Creek (Susquehanna River watershed) via the Harford County Water and Sewer Division — the Harford County north Maryland Baltimore suburban corridor (Precambrian–Paleozoic calcareous-moderate Maryland Piedmont gneiss and Cambrian Wissahickon Schist — the Harford County crystalline Piedmont; Bush River watershed supply with treatment); moderately hard supply at 134 mg/L in Harford County.
