What Makes Westwood's Water Unique?
Local geology and source profile
Westwood, New Jersey, in Bergen County — a Bergen County borough adjacent to Park Ridge and Woodcliff Lake in the north Bergen County suburbs — receives its water from Suez Water New Jersey, drawing from Oradell Reservoir on the Hackensack River through the northeast New Jersey distribution.
The soft 67.5 mg/L hardness and TDS of 118.8 mg/L reflect the Bergen County Oradell Reservoir supply's soft character — the Precambrian Highlands Gneiss is highly insoluble, and Jurassic Newark Formation basalt and sandstone contribute minimal dissolved minerals to the Hackensack watershed in the Bergen County Highlands (compare Park Ridge NJ: 65/114 in Bergen County comparable; Woodcliff Lake NJ: 69/123 in Bergen County comparable; Westwood consistent soft from the same Bergen County Oradell Reservoir Precambrian insoluble supply). The Hackensack watershed — Precambrian Highlands Gneiss (insoluble — primary dilutant), Jurassic Newark Formation (slightly insoluble — secondary dilutant), and Quaternary glacial outwash (slightly calcareous — minor TDS).
At 67.5 mg/L with TDS 119, Westwood's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 6.7 ppt warrants a certified drinking water filter given the Bergen County northeast New Jersey industrial and Superfund site legacy. Review Suez Water New Jersey's annual water quality report.
Geology & Source: Westwood in Bergen County draws from the Suez Water NJ on Oradell Reservoir (Bergen County, northeast New Jersey) — the Hackensack River watershed drains Precambrian Highlands Gneiss (insoluble) and Jurassic Newark Formation (slightly insoluble) — New Jersey Bergen County Oradell Reservoir Precambrian insoluble supply produces soft water at 67.5 mg/L with TDS 118.8 mg/L.
