Lakewood Water Hardness & Quality Report (2026)

Lakewood Township, New Jersey, in Ocean County — the fastest-growing municipality in New Jersey, a major Orthodox Jewish community and religious center (Beth Medrash Govoha — the largest Torah study institution in North America outside Israel), home of Georgian Court University — draws its municipal water supply from the Kirkwood–Cohansey Aquifer and surface water via New Jersey American Water Ocean District. Water hardness in Lakewood measures 164.5 mg/L — classified as hard.

Lakewood's hard supply — markedly harder than the naturally soft Kirkwood–Cohansey Aquifer source (the Pinelands aquifer is naturally very soft, comparable to Jackson NJ at 60 mg/L) — reflects the dense, extensively developed Lakewood distribution infrastructure. Lakewood Township has undergone extraordinary population growth in the 2000s–2020s as the largest Orthodox Jewish community outside New York, and the distribution system includes a complex mix of infrastructure ages: new mains in rapidly developed residential areas and very old mains in older Lakewood neighborhoods. The extensive and complex distribution network, combined with the hard water source blending in the Ocean County system, produces the hard 164.5 mg/L — substantially elevated above the Pinelands aquifer's natural softness.

At 164.5 mg/L, Lakewood 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. New Jersey American Water consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
