Taunton Water Hardness & Quality Report (2026)

The Taunton Water Division serves approximately 62,165 people in the City of Taunton and surrounding areas in Bristol County, Massachusetts. The utility sources water from the Taunton River and local reservoirs, supplemented by groundwater wells. Treatment occurs at the city's water treatment facilities, with regular testing reported in the annual Consumer Confidence Report available at taunton-ma.gov. Water Superintendent Michael Arruda can be reached at (508) 821-1045 for further details. The Taunton River Watershed covers 562 square miles, draining into Mount Hope Bay.

The watershed is underlain by glacial till, sand, and gravel deposits from the Pleistocene epoch overlying fractured bedrock. The Narragansett Basin (Carboniferous age) contributes sandstones, conglomerates, and volcanics, while the Avalon terrane adds metamorphic rocks. Stratified drift aquifers supply groundwater, with surface water picking up dissolved ions from soils and bedrock as it flows, and groundwater dissolving minerals from fractures in the bedrock. This mix of sedimentary and igneous formations imparts a moderately mineralised character to the blended supply, influenced by seasonal recharge patterns.

Moderately hard water promotes moderate scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency over time. It may leave spots on glassware and reduce soap lathering. Regular descaling with vinegar, installing drain screens, and flushing water heaters annually help mitigate these effects. A water softener is recommended for optimal appliance performance and skin and hair benefits. The 2025 water quality report shows no MCL violations; three contaminants exceed EPA health guidelines, including potential PFAS — filters are advised for extra protection. pH is typically neutral, and lead/copper levels meet action levels via corrosion control.
