What Makes Maynard's Water Unique?
Local geology and source profile
Maynard, Massachusetts, in Middlesex County — a Middlesex County town adjacent to Stow and Acton on the Assabet River in east-central Massachusetts — receives its water from the Town of Maynard Water Department, drawing from the Fort Meadow Reservoir through the east-central Massachusetts distribution.
The very soft 28.5 mg/L hardness and very low TDS of 46.1 mg/L reflect the Middlesex County supply's very soft central Massachusetts upland character — the Precambrian Nashoba Formation and Paleozoic Marlboro Formation are insoluble metamorphic formations in the Massachusetts Upland; the Fort Meadow Reservoir draws from clean granite and schist upland with virtually no dissolved mineral content (compare Stow MA: 25/41 in Middlesex County comparable; Acton MA: 31/51 in Middlesex County comparable; Maynard consistent very soft from the same Middlesex County Fort Meadow Reservoir Precambrian insoluble supply). The Fort Meadow Reservoir — Precambrian Nashoba Formation (insoluble — primary dilutant), Paleozoic Marlboro Formation (insoluble — secondary dilutant), and Quaternary Assabet River glaciofluvial deposit (sandy insoluble — minimal TDS).
At 28.5 mg/L with TDS 46, Maynard's water is very soft — virtually no scale, but very soft water can be corrosive to metal plumbing. Annual corrosion checks are recommended. The PFAS level of 5.1 ppt warrants a certified drinking water filter. Review the Town of Maynard's annual water quality report.
Geology & Source: Maynard in Middlesex County draws from the Maynard Water on the Assabet River/Fort Meadow Reservoir (Middlesex County, east-central Massachusetts) — the east-central Massachusetts upland at Middlesex County draws from Precambrian Nashoba Formation (insoluble) and Paleozoic Marlboro Formation (insoluble) — Massachusetts Middlesex County Fort Meadow Reservoir Precambrian insoluble supply produces very soft water at 28.5 mg/L with TDS 46.1 mg/L.
