What Makes Westfield's Water Unique?
Local geology and source profile
Westfield, New Jersey, in Union County — a major Union County New York metropolitan suburban community (Westfield is one of the most prestigious and desirable communities in New Jersey's New York suburban corridor — a Union County town with a charming downtown, excellent public schools, and high property values; Westfield's downtown (Elm Street pedestrian district) is one of the most attractive small downtown commercial districts in New Jersey, known for its independent boutiques, restaurants, and a vibrant street life); home of a significant New York commuter population (Westfield's NJ Transit train station provides direct service to Penn Station New York — one of the primary NJ Transit commuter rail communities in Union County), a diverse Union County community with a primarily affluent professional and New York commuter population, and one of New Jersey's most desirable suburban communities — draws its municipal water supply via New Jersey American Water. Water hardness in Westfield measures 66 mg/L — classified as moderately soft.
Westfield's moderate softness reflects the north New Jersey NJAW system's effective treatment. The NJAW distributes Passaic River watershed supply (draining Triassic Newark Basin Passaic Formation — calcareous-poor) to the Union County Westfield zone, producing the moderately soft 66 mg/L.
With hardness at 66 mg/L, Westfield residents enjoy moderately soft water. New Jersey American Water consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Passaic River watershed via the New Jersey American Water (NJAW) — the Union County north New Jersey New York metropolitan Westfield corridor (Triassic calcareous-poor Newark Basin Passaic Formation — the calcareous-poor north New Jersey Triassic Piedmont; NJAW effective treatment producing soft supply); moderately soft supply at 66 mg/L in Union County.
