Hudson County water hardness
Hudson County water is mostly surface water piped in from reservoirs to the west, which keeps hardness lower here than in most of the state.
Across the 5 Hudson County municipalities with published figures, hardness averages 6.3 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 Veolia Bayonne Service System, Harrison System, Veolia Service System, North Jersey District Water Supply, Veolia Hackensack Service System.
