Water

Wells by the Charles and Neponset

The Dedham-Westwood Water District serves about 41,630 people from seventeen wells. Eleven sit by the Charles River near Bridge Street in Dedham and one by the Neponset near University Avenue; the rest are in Westwood. Last year about 23% of the supply came from the MWRA. The water is aerated to oxidize iron and manganese, filtered, and treated with orthophosphate for corrosion control.

The 2025 report put hardness at 74 to 134 ppm, an average of 6.0 grains per gallon. The USGS calls 61 to 120 mg/L moderately hard. Sodium averaged 84.9 ppm against the state's 20 ppm guideline, and chloride averaged 165 ppm, which the report ties partly to deicing salt.

PFAS

PFAS treatment at White Lodge

In October 2025 the district began building a 2,800-square-foot addition to its White Lodge treatment plant in Westwood to remove PFAS by ion exchange, sized for 4.5 million gallons a day. It expects to finish in spring 2027 and posts monthly test results at dwwd.org/pfas. Questions go to the district at 781-329-7090.
