Vineland Water Hardness & Quality Report (2026)

Vineland, New Jersey, the Cumberland County seat in southern New Jersey — the largest city by area in New Jersey (though a relatively modest population), known for its historic Italian-American farming community and Vineland's role in the development of concord grape juice — draws its municipal water supply from the Cohansey Aquifer (Miocene Cohansey Sand) and Kirkwood Formation via the City of Vineland Division of Engineering Water Division, pumping from Cumberland County Coastal Plain aquifer wells. Water hardness in Vineland measures 37 mg/L — classified as very soft.

Vineland's very soft supply reflects the Cumberland County Coastal Plain's exceptional siliceous quartz sand aquifer geology. The Cohansey Aquifer (formed in the Miocene Cohansey Sand — a pure siliceous quartz sand and gravel with minimal calcareous content) is one of the largest and purest siliceous aquifers in the northeastern United States, underlying most of the New Jersey Pine Barrens and adjacent Coastal Plain. The Cohansey Sand in Cumberland County is a well-sorted quartz sand with essentially no calcareous cement, carbonate minerals, or reactive calcareous components — quartz ($SiO_2$) dissolves extremely slowly, contributing virtually no dissolved calcium or magnesium. The resulting 37 mg/L in Vineland is among the softest municipal groundwater supplies in New Jersey.

With hardness at 37 mg/L, Vineland residents enjoy very soft water with essentially no scale challenges. City of Vineland Division of Engineering Water Division consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
