What Makes Hull's Water Unique?
Local geology and source profile
Hull, Massachusetts, in Plymouth County — a Plymouth County town adjacent to Hingham and Cohasset on the Nantasket Peninsula in southeast Massachusetts — receives its water from the Hull Water Department, drawing from the MWRA Cosgrove/Wachusett watershed through the east Massachusetts distribution.
The moderately hard 103.5 mg/L hardness and TDS of 254.4 mg/L reflect the Plymouth County supply's moderate character — the Precambrian Wachusett Mountain Gneiss provides insoluble dilution, while Hull's coastal peninsula location and distribution infrastructure concentrate mineral content to moderate hardness levels; Hull receives MWRA supply with slightly higher TDS than inland distribution communities due to the south coast peninsula delivery zone (compare Hingham MA: 100/245 in Plymouth County comparable; Cohasset MA: 106/264 in Norfolk County comparable; Hull consistent moderate from the same Plymouth County MWRA watershed Precambrian insoluble supply). The MWRA Wachusett watershed — Precambrian Wachusett Mountain Gneiss (insoluble — primary dilutant), Cambrian Clinton-Newbury Belt (slightly calcareous — primary hardness contributor), and Quaternary South Shore glacial till (slightly calcareous — TDS contributor).
At 103.5 mg/L with TDS 254, Hull's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 10.3 ppt is very high — a certified filter with PFAS removal is strongly recommended. Review the Hull Water Department's annual water quality report.
Geology & Source: Hull in Plymouth County draws from the Hull Water on the Massachusetts Water Resources Authority Cosgrove/Wachusett supply (Plymouth County, east Massachusetts) — the MWRA watershed draws from Precambrian Wachusett Mountain Gneiss (insoluble) and Cambrian Clinton-Newbury Belt (slightly calcareous) — Massachusetts Plymouth County MWRA watershed Precambrian insoluble supply produces moderately hard water at 103.5 mg/L with TDS 254.4 mg/L.
