What Makes Endwell's Water Unique?
Local geology and source profile
Endwell, New York, in Broome County — a Broome County hamlet adjacent to Johnson City and Binghamton on the Susquehanna River in the Southern Tier of New York — receives its water from Broome County Water or Binghamton Water, drawing from the Susquehanna River watershed through the south-central New York distribution.
The soft 83.5 mg/L hardness and TDS of 144.2 mg/L reflect the Broome County Susquehanna River supply's soft character — the Devonian Catskill Formation and Silurian Vernon Shale are predominantly insoluble to slightly calcareous sedimentary formations in the Appalachian Plateau, and the Susquehanna at Binghamton averages quite soft from its forested Catskill and Allegheny headwaters (compare Johnson City NY: 81/140 in Broome County comparable; Binghamton NY: 85/148 in Broome County comparable; Endwell consistent soft from the same Broome County Susquehanna River Devonian calcareous supply). The Susquehanna watershed at Broome County — Devonian Catskill Formation (slightly calcareous — primary hardness contributor), Silurian Vernon Shale (slightly calcareous — secondary contributor), and Quaternary Susquehanna alluvium (slightly calcareous — minor TDS).
At 83.5 mg/L with TDS 144, Endwell's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 4.2 ppt is moderate — a certified drinking water filter provides added protection. Review Broome County Water's annual water quality report.
Geology & Source: Endwell in Broome County draws from the Broome County Water on Susquehanna River supply (Broome County, south-central New York) — the Susquehanna at Broome County drains Devonian Catskill Formation (slightly calcareous) and Silurian Vernon Shale (slightly calcareous) — New York Broome County Susquehanna River Devonian calcareous supply produces soft water at 83.5 mg/L with TDS 144.2 mg/L.
