What Makes River Edge's Water Unique?
Local geology and source profile
River Edge, New Jersey, in Bergen County — a Bergen County borough adjacent to New Milford and River Vale in north-central New Jersey — receives its water from New Jersey American Water, drawing from Oradell Reservoir on the Hackensack River through the north-central New Jersey distribution.
The very soft 40 mg/L hardness and very low TDS of 61.6 mg/L reflect the Bergen County Hackensack supply's very soft character — the Precambrian Highlands Gneiss is highly insoluble and dominates the upper Hackensack watershed, while Cambrian Kittatinny Limestone contributes only trace calcareous content to this pristine mountain reservoir (compare New Milford NJ: 38/58 in Bergen County comparable; River Vale NJ: 41/63 in Bergen County comparable; River Edge consistent very soft from the same Bergen County Oradell Reservoir Precambrian insoluble supply). The Hackensack watershed at Bergen County — Precambrian Highlands Gneiss (insoluble — primary dilutant), Cambrian Kittatinny Limestone (slightly calcareous — minor hardness contributor), and Triassic Passaic Formation (slightly calcareous — minor TDS).
At 40 mg/L with TDS 62, River Edge has very soft water — virtually no scale buildup. Soft water can be gently corrosive — check for blue-green copper staining in older plumbing. The PFAS level of 5.2 ppt warrants a certified drinking water filter. Review NJ American Water's annual water quality report for the latest monitoring data.
