What Makes Pennsville's Water Unique?
Local geology and source profile
Pennsville, New Jersey, in Salem County — a Salem County township adjacent to Salem and Carneys Point on the Delaware River estuary in southwest New Jersey — receives its water from the Pennsville Water Department or a local utility, drawing from the Delaware River through the southwest New Jersey distribution.
The moderately hard 125 mg/L hardness and TDS of 277.7 mg/L reflect the Salem County Delaware supply's moderate calcareous character — the Precambrian Highlands Gneiss in the upper Delaware watershed contributes insoluble dilution while Cambrian Kittatinny Limestone calcareous formations and Cretaceous Coastal Plain calcareous sediments contribute dissolved minerals to the blended Delaware River water (compare Salem NJ: 122/272 in Salem County comparable; Carneys Point NJ: 128/282 in Salem County comparable; Pennsville consistent moderate from the same Salem County Delaware River Precambrian-Cambrian supply). The Delaware watershed at Salem County — Precambrian Highlands Gneiss (insoluble — dilutant), Cambrian Kittatinny Limestone (slightly calcareous — primary hardness contributor), and Quaternary Delaware alluvium (calcareous — TDS contributor).
At 125 mg/L with TDS 278, Pennsville's water is moderately hard — mild scale buildup over time. Semi-annual descaling is appropriate. The PFAS level of 10.0 ppt is very high — a certified drinking water filter with PFAS removal is strongly recommended — the Salem County southwest New Jersey industrial (Dupont/Chemours Salem Works) and nuclear facilities contribute to Pennsville's very elevated PFAS readings.
Geology & Source: Pennsville in Salem County draws from the Pennsville Water on the Delaware River (Salem County, southwest New Jersey) — the Delaware watershed at Salem County drains Precambrian Highlands Gneiss (insoluble) and Cambrian Kittatinny Limestone (slightly calcareous) — New Jersey Salem County Delaware River Precambrian calcareous supply produces moderately hard water at 125 mg/L with TDS 277.7 mg/L.
