Union County water hardness
Union County mixes Elizabethtown-era investor-owned systems with the Short Hills service system, so neighbouring towns can report very different calcium levels.
Across the 7 Union County municipalities with published figures, hardness averages 9.2 grains per gallon — 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 Short Hills Service System, Liberty Service System.
