What Makes Spring Valley's Water Unique?
Local geology and source profile
Spring Valley, New York, in Rockland County — a major south Rockland County village (Spring Valley is a significant Rockland County village — one of the most densely populated and diverse communities in Rockland County, serving as the primary commercial hub of south Rockland County), a highly diverse Rockland County community with a significant Haitian-American (one of the largest Haitian communities in New York State), Guatemalan-American, and Ultra-Orthodox Jewish-American population (Spring Valley is adjacent to the Ramapo Orthodox Jewish communities of Monsey — the area has one of the most significant Ultra-Orthodox Jewish populations in the country), home of a major West African immigrant community, and a community undergoing significant demographic change — draws its municipal water supply via United Water New York (Suez Water Rockland). Water hardness in Spring Valley measures 177 mg/L — classified as hard.
Spring Valley's hard supply reflects the south Rockland County Hudson Valley watershed mix. The Rockland County water system draws from the Precambrian Ramapo Mountains gneiss (calcareous-poor) and the Cambrian–Ordovician Rockland County carbonate sequence (calcareous-moderate dolomite). Treatment produces the hard 177 mg/L.
At 177 mg/L, Spring Valley residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. United Water New York consistently delivers water meeting all New York State DEC and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Rockland County water system via the United Water New York (Suez Water Rockland) — the Rockland County southeast New York Hudson Valley Spring Valley corridor (Precambrian calcareous-poor Ramapo Mountains gneiss and Cambrian–Ordovician calcareous-moderate carbonate of the Rockland County Hudson Valley; Rockland County supply with treatment); hard supply at 177 mg/L in Rockland County.
