What Makes Weehawken's Water Unique?
Local geology and source profile
Weehawken, New Jersey, in Hudson County — a Hudson County township adjacent to Union City and West New York across the Hudson River from midtown Manhattan — receives its water from Suez Water New Jersey (formerly United Water), drawing from the Wanaque Reservoir or Passaic River (Hudson County) through the northeast New Jersey distribution.
The moderately soft 57.5 mg/L hardness and TDS of 96.7 mg/L are among the softest in the New Jersey metro, similar to Berkeley Heights (43.5 mg/L) — reflecting the New Jersey Highlands Precambrian gneiss reservoir's predominantly insoluble crystalline watershed with minimal calcareous dissolution. The Wanaque Reservoir watershed at Hudson County drains the New Jersey Highlands — Precambrian Losee Gneiss (insoluble — primary dilutant), Precambrian Byram Intrusive Suite (insoluble), Cambrian calcareous formations (slightly calcareous — minor contributor), and Pleistocene glacial outwash.
At 57.5 mg/L, Weehawken's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 6.2 ppt warrants a certified drinking water filter — the Hudson County northeast New Jersey industrial waterfront and the Newark Bay corridor contribute to Weehawken's readings.
Geology & Source: Weehawken in Hudson County draws from the United Water New Jersey on the Passaic River or Wanaque Reservoir (Hudson County, northeast New Jersey) — the Wanaque drains the New Jersey Highlands (Precambrian Losee Gneiss — insoluble) — New Jersey Hudson County Highlands Precambrian crystalline reservoir produces moderately soft water at 57.5 mg/L with TDS 96.7 mg/L.
