What Makes Sayreville Junction's Water Unique?
Local geology and source profile
Sayreville Junction (Sayreville), New Jersey, in Middlesex County on the Raritan Bay — a working-class Middlesex County community with a significant Ukrainian-American, Polish-American, and Filipino-American heritage (notable as the hometown of musician Jon Bon Jovi), a major industrial waterfront community on the Raritan River, and a South Amboy–Sayreville waterfront community in the Raritan Bay corridor — draws its municipal water supply from the Raritan Formation aquifer and Raritan River supply via the Sayreville Borough Water Division. Water hardness in Sayreville measures 104 mg/L — classified as moderately hard.
Sayreville's moderate hardness reflects the central Middlesex County Coastal Plain aquifer characteristics and Raritan River treatment. The Raritan Formation Aquifer (the Cretaceous Raritan Formation in Middlesex County — moderately calcareous sandy marine sediment) and the Raritan River supply (the Raritan River drains the New Jersey Highlands — Precambrian calcareous-moderate crystalline terrain). The Sayreville distribution infrastructure includes older Middlesex County industrial waterfront mains, producing the moderate 104 mg/L at Sayreville Junction.
At 104 mg/L, Sayreville residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended for faucet aerators and showerheads. Sayreville Borough Water Division consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from the Old Bridge Aquifer (Cohansey Aquifer) and Raritan River (New Jersey American Water) via the Sayreville Borough Water Division — the Middlesex County central New Jersey Raritan Bay corridor (Cretaceous Raritan Formation and Raritan River watershed calcareous-moderate terrain); moderately hard supply at 104 mg/L in Middlesex County.
