What Makes West Orange's Water Unique?
Local geology and source profile
West Orange, New Jersey, in Essex County — home of Thomas Edison National Historical Park (Edison's Glenmont estate and laboratory complex, where Edison invented the phonograph, motion pictures, and the alkaline storage battery), a diverse Essex County inner suburb with significant Haitian-American and African-American communities, and the historic Llewellyn Park (the first planned residential community in the United States, 1857) — draws its municipal water supply from the Passaic River (Wanaque Reservoir) via the Essex County Utilities Authority (ECUA) and the Township of West Orange Water Division. Water hardness in West Orange measures 64 mg/L — classified as moderately soft.
West Orange's moderate softness reflects the Wanaque Reservoir's calcium-poor New Jersey Highlands watershed. The Wanaque Reservoir drains the New Jersey Highlands (Proterozoic Byram Intrusive Suite granodiorite and gneiss — calcium-poor crystalline Precambrian terrain). West Orange also receives water from the Essex County Utilities Authority Passaic Valley supply, blended with the soft Highlands reservoir source. The ECUA system treats and distributes the blended supply through West Orange's Essex County distribution infrastructure, producing the moderate 64 mg/L — very soft for a New Jersey community.
With hardness at 64 mg/L, West Orange residents enjoy moderately soft water with minimal scale challenges. Essex County Utilities Authority and West Orange Water Division consistently deliver water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Passaic River (Wanaque and Monksville Reservoirs) via the Essex County Utilities Authority (ECUA) and the Township of West Orange Water Division — the Essex County New Jersey Watchung Mountains (Proterozoic Highlands crystalline and Jurassic Watchung Basalt watershed); moderately soft supply at 64 mg/L — reflecting the Wanaque Reservoir's calcium-poor New Jersey Highlands watershed.
