What Makes Waldwick's Water Unique?
Local geology and source profile
Waldwick, New Jersey, in Bergen County — a Bergen County borough adjacent to Ridgewood and Ho-Ho-Kus in the north Jersey suburbs — receives its water from the Waldwick Water Department, drawing from the Ramapo River watershed through the northeast New Jersey distribution.
The very soft 44.5 mg/L hardness and very low TDS of 70.1 mg/L reflect the Bergen County supply's very soft Ramapo Mountain character — the Precambrian Losee Gneiss and Cambrian Franklin Marble are insoluble-slightly calcareous formations in the New Jersey Highlands; the Ramapo River watershed draws from clean Precambrian Highlands crystalline rock with minimal dissolved mineral content, producing some of the softest municipal water in New Jersey (compare Ridgewood NJ: 41/64 in Bergen County comparable; Ho-Ho-Kus NJ: 47/76 in Bergen County comparable; Waldwick consistent very soft from the same Bergen County Ramapo River Precambrian insoluble supply). The Ramapo River watershed — Precambrian Losee Gneiss (insoluble — primary dilutant), Cambrian Franklin Marble (slightly calcareous — primary hardness contributor), and Quaternary Bergen County glaciofluvial deposit (slightly calcareous — minimal TDS).
At 44.5 mg/L with TDS 70, Waldwick's water is very soft — virtually no scale, but very soft water can be corrosive to metal plumbing. Annual corrosion checks are recommended. The PFAS level of 5.4 ppt warrants a certified drinking water filter. Review the Waldwick Water Department's annual water quality report.
