Cherry Hill Water Hardness & Quality Report (2026)

Cherry Hill, New Jersey, in Camden County southwest of Philadelphia — one of New Jersey's most populous townships and a major South Jersey suburban and commercial center — draws its municipal water supply through New Jersey American Water (NJ American Water Camden Division), sourcing from the Delaware River treated at the Camden Water Treatment facility and from local Coastal Plain groundwater wells accessing the Potomac–Raritan–Magothy (PRM) Aquifer in Camden County. Water hardness in Cherry Hill measures 138 mg/L — classified as moderately hard.

Cherry Hill's moderate hardness reflects the Camden County supply blend from the Delaware River and New Jersey Coastal Plain groundwater. The Delaware River at Camden receives drainage from the entire Delaware River Basin — the Catskills, Delaware Water Gap Appalachian carbonates, and Pennsylvania Piedmont — producing a moderately hard water supply. The local PRM Aquifer wells in Camden County access Cretaceous Raritan Formation (calcareous quartz sand with some carbonate cement in the Woodbury Clay–Merchantville Formation sequence), contributing moderate dissolved minerals. The blend of Delaware River surface water and Coastal Plain groundwater produces the 138 mg/L moderate hardness in Cherry Hill.

At 138 mg/L, Cherry Hill residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. New Jersey American Water consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
