South Vineland Water Hardness & Quality Report (2026)

South Vineland, New Jersey, the southern section of Vineland City in Cumberland County — the agricultural and residential southern end of the City of Vineland, one of New Jersey's largest cities by area — draws its municipal water supply from the Kirkwood–Cohansey Aquifer and the deeper Atlantic City 800-Foot Sand (Kirkwood Formation, Miocene) via the City of Vineland Division of Engineering Water Division. Water hardness in South Vineland measures 164 mg/L — classified as hard, strikingly harder than north Vineland (37 mg/L).

South Vineland's hard supply — in sharp contrast to the very soft north Vineland supply from the shallow Cohansey Aquifer — reflects different well depths and aquifer zones in the south Vineland water distribution system. The deeper Atlantic City 800-Foot Sand (the Kirkwood Formation deep sand member, Miocene) beneath south Cumberland County has substantially higher calcareous content than the shallow Cohansey Sand — the deeper Kirkwood Formation sands include more calcareous cement from deeper burial and from calcareous shell material of the Miocene marine deposits. The south Vineland wells drawing from the deeper Kirkwood Sand produce the elevated 164 mg/L, while the shallower north Vineland Cohansey wells produce the very soft 37 mg/L.

At 164 mg/L, South Vineland residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. City of Vineland Water Division consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
