What Makes Mount Laurel's Water Unique?
Local geology and source profile
Mount Laurel, New Jersey, in Burlington County in the greater Philadelphia suburbs — a major south New Jersey suburban community, nationally known for the landmark Mount Laurel Doctrine (a 1975 New Jersey Supreme Court ruling requiring municipalities to provide affordable housing — one of the most significant exclusionary zoning rulings in US history), a major Burlington County corporate headquarters and commercial community, and a diverse Philadelphia south New Jersey suburban community — draws its municipal water supply from the PRM Aquifer via New Jersey American Water and the Mount Laurel Township Water Division. Water hardness in Mount Laurel measures 100.5 mg/L — classified as moderately hard.
Mount Laurel's moderate hardness reflects the Burlington County Coastal Plain aquifer's moderately calcareous geology. The Potomac–Raritan–Magothy Aquifer in Burlington County is hosted in the Cretaceous Potomac Group (moderately calcareous sandy marine and estuarine sediment of the Atlantic Coastal Plain). The Mount Laurel Aquifer section (a distinct sandy Cretaceous unit within the Potomac Group, named for the township) consists of quartz-dominated sand with some calcareous cemented zones. New Jersey American Water's treatment of this moderately calcareous Coastal Plain supply produces the moderate 100.5 mg/L.
At 100.5 mg/L, Mount Laurel residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended for faucet aerators and showerheads. New Jersey American Water consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Potomac–Raritan–Magothy (PRM) Aquifer via the New Jersey American Water and the Mount Laurel Township Water Division — the Burlington County south New Jersey Coastal Plain (Cretaceous Potomac Group and Raritan Formation — moderately calcareous sandy Coastal Plain aquifer); moderately hard supply at 100.5 mg/L in Burlington County.
