Bergen County water hardness

Bergen County households are largely served by Veolia's Hackensack system and a set of borough-run wells, so readings swing widely between the Hackensack River supply and local groundwater.

Across the 2 Bergen County municipalities with published figures, hardness averages 11.3 grains per gallon — very 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 Mahwah municipal system, Veolia Hackensack Service System.
