What Makes Totowa's Water Unique?
Local geology and source profile
Totowa, New Jersey, in Passaic County — a Passaic County borough adjacent to Paterson and Wayne in northeast New Jersey — receives its water from the North Jersey District Water Supply Commission, drawing from Wanaque Reservoir through the northeast New Jersey distribution.
The hard 165 mg/L hardness and TDS of 419.6 mg/L reflect the Passaic County supply's hard character — the Precambrian Grenville Province gneiss provides insoluble dilution, while Cambrian Green Pond Conglomerate and Triassic Newark Basin sediments contribute calcareous mineral content from the Passaic Valley geological corridor (compare Paterson NJ: 162/411 in Passaic County comparable; Wayne NJ: 167/428 in Passaic County comparable; Totowa consistent hard from the same Passaic County Wanaque Reservoir Precambrian supply). The Wanaque watershed — Precambrian Grenville Province gneiss (insoluble — primary dilutant), Cambrian Green Pond Conglomerate (slightly calcareous — primary hardness contributor), and Triassic Newark Basin sediment (calcareous — TDS contributor).
At 165 mg/L with TDS 420, Totowa's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 12.2 ppt is very high — a certified filter with PFAS removal is strongly recommended — Passaic County New Jersey industrial legacy (Passaic River superfund sites) contributes significantly to Totowa's very elevated PFAS readings. Review North Jersey District Water Supply Commission's annual report.
Geology & Source: Totowa in Passaic County draws from the North Jersey District Water on Wanaque Reservoir (Passaic County, northeast New Jersey) — the Wanaque watershed drains Precambrian Grenville Province gneiss (insoluble) and Cambrian Green Pond Conglomerate (slightly calcareous) — New Jersey Passaic County Wanaque Reservoir Precambrian supply produces hard water at 165 mg/L with TDS 419.6 mg/L.
