What Makes Woodbridge's Water Unique?
Local geology and source profile
Woodbridge, New Jersey, in Middlesex County — a Middlesex County township adjacent to Perth Amboy and Rahway in the north New Jersey industrial-suburban corridor, one of the largest townships in New Jersey by population — receives its municipal water from New Jersey American Water, drawing from the Raritan River at the New Brunswick intake or through the Raritan Basin regional water supply system.
The moderately soft 77.5 mg/L hardness and TDS of 142.8 mg/L reflect the Raritan River watershed's New Jersey Highlands crystalline character. The Raritan River drains the New Jersey Highlands (Proterozoic Losee Gneiss and Manhattan Schist — insoluble crystalline) and the southern Newark Basin (Triassic Lockatong Argillite, Passaic Formation red beds — somewhat more calcareous). The combination produces the moderately soft water characteristic of the central New Jersey Raritan supply — softer than the Morris County groundwater (harder glacial moraine wells) but similar to other Raritan surface supplies.
At 77.5 mg/L, Woodbridge's water is moderately soft — comfortable for household use. Scale forms slowly, soap lathers well, and appliances operate efficiently. Semi-annual descaling is adequate. The PFAS level of 7.3 ppt warrants a certified drinking water filter — the Raritan River industrial corridor (3M Woodbridge plant legacy — a documented PFAS manufacturing site), Perth Amboy industrial complex, and the New Jersey Raritan PFAS corridor (one of the most PFAS-contaminated river systems in New Jersey) contribute to Woodbridge's elevated readings.
Geology & Source: Woodbridge in Middlesex County draws from New Jersey American Water on the Raritan River (New Brunswick intake) or the Raritan Basin watershed — the Raritan drains the New Jersey Highlands (Proterozoic gneiss) and the Newark Basin (Triassic Lockatong Argillite, red beds) — New Jersey Piedmont crystalline and Triassic Newark Basin drainage produces moderately soft water at 77.5 mg/L with TDS 143 mg/L in this Middlesex County New Jersey township.
