Ocean County water hardness
Ocean County utilities pump from sandy coastal aquifers. Hardness is generally moderate, with iron and manganese the more common nuisance findings.
Across the 5 Ocean County municipalities with published figures, hardness averages 5.0 grains per gallon — moderately hard water on the USGS scale. Because most towns here buy treated water rather than produce it, neighbouring municipalities on the same system report the same number; the systems represented below are Coastal North Service System, Jackson Township MUA, Lakewood municipal system, New Egypt System, Whiting municipal system.
