What Makes West Haverstraw's Water Unique?
Local geology and source profile
West Haverstraw, New York, in Rockland County — a Rockland County village adjacent to Haverstraw and Stony Point on the Hudson River in southeast New York — receives its water from United Water NY, drawing from the Catskill/Delaware watershed through the lower Hudson Valley distribution.
The hard 149 mg/L hardness and TDS of 356.1 mg/L reflect the Rockland County supply's hard blended character — while the Catskill watershed supplies primarily soft mountain water, Rockland County's distribution blends with Ordovician Hudson Valley Shale-sourced groundwater and the local lower Hudson Valley geology concentrates moderate to hard mineral content (compare Haverstraw NY: 145/347 in Rockland County comparable; Stony Point NY: 152/365 in Rockland County comparable; West Haverstraw consistent hard from the same Rockland County Catskill watershed Devonian supply). The Lower Hudson Valley supply — Devonian Catskill Formation (insoluble — primary dilutant), Ordovician Hudson Valley Shale (slightly calcareous — primary hardness contributor), and Quaternary Hudson River alluvium (calcareous — TDS contributor).
At 149 mg/L with TDS 356, West Haverstraw's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 7.2 ppt warrants a certified drinking water filter. Review United Water NY's annual water quality report.
Geology & Source: West Haverstraw in Rockland County draws from the United Water on the Catskill/Delaware watershed (Rockland County, southeast New York) — the lower Hudson Valley supply draws from Devonian Catskill Formation (insoluble) and Ordovician Hudson Valley Shale (slightly calcareous) — New York Rockland County Catskill watershed Devonian supply produces hard water at 149 mg/L with TDS 356.1 mg/L.
