What Makes Kinnelon's Water Unique?
Local geology and source profile
Kinnelon, New Jersey, in Morris County — a Morris County borough adjacent to Butler and Bloomingdale in the north New Jersey Highlands — receives its water from New Jersey American Water, drawing from the Boonton Reservoir through the north New Jersey distribution.
The hard 151.5 mg/L hardness and TDS of 368.9 mg/L reflect the Morris County supply's hard blended character — while the Precambrian Highlands Gneiss provides insoluble dilution in the Boonton watershed, the Triassic Passaic Formation and Kinnelon's north Morris County distribution zone concentrate harder mineral content from the blended NJ American Water grid (compare Butler NJ: 147/359 in Morris County comparable; Bloomingdale NJ: 155/378 in Passaic County comparable; Kinnelon consistent hard from the same Morris County Boonton Reservoir Precambrian supply). The Boonton watershed — Precambrian Highlands Gneiss (insoluble — primary dilutant), Triassic Passaic Formation (slightly calcareous — primary hardness contributor), and Quaternary Highlands glacial till (calcareous — TDS contributor).
At 151.5 mg/L with TDS 369, Kinnelon's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 11.4 ppt is very high — a certified filter with PFAS removal is strongly recommended. Review New Jersey American Water's annual water quality report.
