What Makes Roselle Park's Water Unique?
Local geology and source profile
Roselle Park, New Jersey, in Union County — a Union County borough adjacent to Roselle and Union in north-central New Jersey — receives its water from NJ American Water, drawing from the Passaic River via Wanaque Reservoir (Union County) through the north-central New Jersey distribution.
The soft 51.5 mg/L hardness and TDS of 84.2 mg/L reflect the north-central New Jersey Union County Passaic-Wanaque supply's soft character — consistent with other New Jersey Highlands reservoir communities (Metuchen: 63.5 mg/L; Bradley Gardens: 59 mg/L) drawing from the predominantly insoluble Precambrian gneiss watershed of the north Jersey Highlands. The Wanaque Reservoir watershed at Union County — Precambrian Losee Gneiss (insoluble — primary dilutant), Precambrian New Jersey Highlands gneiss (insoluble — dilutant), and Cambrian calcareous formations (slightly calcareous — trace hardness contributor).
At 51.5 mg/L, Roselle Park's water is soft — minimal scale buildup, appliances last well, and no softening is needed. Water is safe for all uses. The PFAS level of 5.8 ppt warrants a certified drinking water filter — the Union County north-central New Jersey industrial corridor and the Newark metropolitan industrial legacy contribute to Roselle Park's readings.
Geology & Source: Roselle Park in Union County draws from the NJ American Water on the Passaic River via Wanaque Reservoir (Union County, north-central New Jersey) — the Wanaque watershed drains the New Jersey Highlands (Precambrian gneiss — insoluble) and Cambrian calcareous formations — New Jersey Union County Wanaque Reservoir Precambrian-Cambrian watershed produces soft water at 51.5 mg/L with TDS 84.2 mg/L.
