What Makes Hanson's Water Unique?
Local geology and source profile
Hanson, Massachusetts, in Plymouth County — a Plymouth County town adjacent to Halifax and Whitman in the south shore area of southeast Massachusetts — receives its water from the Town of Hanson Water Department, drawing from the Indian Head River watershed through the southeast Massachusetts distribution.
The very soft 49 mg/L hardness and very low TDS of 90.7 mg/L reflect the Plymouth County supply's very soft Coastal Plain character — the Quaternary Cape Cod aquifer outwash and Precambrian Bridgewater Granite are sandy-insoluble formations in the southeast Massachusetts coastal plain; Hanson's water draws from clean sandy outwash deposits with minimal dissolved mineral content, producing very soft water typical of the southeast Massachusetts south shore (compare Halifax MA: 46/86 in Plymouth County comparable; Whitman MA: 51/95 in Plymouth County comparable; Hanson consistent very soft from the same Plymouth County Cape Cod outwash Quaternary insoluble supply). The Indian Head River watershed — Quaternary Cape Cod aquifer outwash (sandy insoluble — primary dilutant), Precambrian Bridgewater Granite (insoluble — secondary dilutant), and Quaternary Plymouth County glaciofluvial deposit (sandy insoluble — minimal TDS).
At 49 mg/L with TDS 91, Hanson's water is very soft — virtually no scale, but soft water can be corrosive to older plumbing. Annual descaling is not necessary; however, check plumbing for corrosion annually. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the Town of Hanson's annual water quality report.
Geology & Source: Hanson in Plymouth County draws from the Hanson Water on the Indian Head River watershed (Plymouth County, southeast Massachusetts) — the southeast Massachusetts coastal plain at Plymouth County draws from Quaternary Cape Cod aquifer outwash (sandy insoluble) and Precambrian Bridgewater Granite (insoluble) — Massachusetts Plymouth County Cape Cod outwash Quaternary insoluble supply produces very soft water at 49 mg/L with TDS 90.7 mg/L.
