What Makes Dumont's Water Unique?
Local geology and source profile
Dumont, New Jersey, in Bergen County — a Bergen County borough adjacent to Haworth and Bergenfield in the north Bergen County corridor — receives its municipal water from New Jersey American Water (NJAW) or Suez Water NJ (formerly United Water), drawing from the Hackensack River watershed through Lake DeForest and the Oradell Reservoir (Bergen County, Hackensack River).
The moderately hard 144.5 mg/L hardness and TDS of 343.5 mg/L reflect the Bergen County Hackensack supply's blended Highlands-Triassic character. The Hackensack watershed drains the New Jersey Highlands (Precambrian Reading Prong gneiss — insoluble crystalline) and the Triassic Newark Basin margin (calcareous Brunswick Formation redbeds — significant hardness contributor). The moderate hardness reflects the Highlands crystalline diluted by Triassic calcareous lowland inflow.
At 144.5 mg/L, Dumont's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 11.0 ppt is very elevated and warrants a certified reverse osmosis drinking water filter — the Teterboro Airport (Bergen County — AFFF in the Hackensack River watershed), the Bergen County industrial corridor, and the northeast New Jersey PFAS complex contribute to Dumont's very elevated readings.
Geology & Source: Dumont in Bergen County draws from New Jersey American Water or United Water on the Hackensack River watershed (Bergen County, Oradell Reservoir) — the Hackensack drains the New Jersey Highlands (Precambrian Reading Prong gneiss) with Triassic lowland contribution — New Jersey Bergen County Hackensack watershed produces moderately hard water at 144.5 mg/L with TDS 343.5 mg/L in this Bergen County New Jersey borough.
