What Makes Collingswood's Water Unique?
Local geology and source profile
Collingswood, New Jersey, in Camden County — a Camden County borough adjacent to Haddon Township and Oaklyn in southwest New Jersey — receives its water from New Jersey American Water, drawing from the Delaware River (Camden County) through the southwest New Jersey distribution.
The moderately hard 144.5 mg/L hardness and TDS of 343.3 mg/L are consistent with Camden County Delaware River communities (Cherry Hill Mall: 138.5 mg/L; Springdale: 165.5 mg/L) — all drawing from the same NJ American Water Delaware River intake system treated to moderate calcareous hardness from the Triassic Brunswick Formation redbeds. The Delaware River at Camden County drains — Triassic Brunswick Formation (calcareous redbeds — primary hardness contributor), Cambrian Hardyston Quartzite (slightly calcareous), and Precambrian Reading Prong crystalline (insoluble — dilutant).
At 144.5 mg/L, Collingswood's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 11.0 ppt warrants a certified reverse osmosis drinking water filter — McGuire Air Force Base (Burlington County — AFFF) and the southwest New Jersey Delaware River industrial corridor contribute to Collingswood's elevated readings.
Geology & Source: Collingswood in Camden County draws from the New Jersey American Water on the Delaware River (Camden County, southwest New Jersey) — the Delaware at Camden drains the Triassic Brunswick Formation (calcareous redbeds) and Precambrian Reading Prong — New Jersey Camden County Delaware River Triassic calcareous watershed produces moderately hard water at 144.5 mg/L with TDS 343.3 mg/L.
