Sodium in Drinking Water

The Westford Water Department (WWD) monitors for sodium in drinking water on an annual basis.

The Massachusetts Department of Environmental Protection (MassDEP) requires all water suppliers (like the Westford Water Department) to notify their local Boards of Health, the Massachusetts Department of Health, and the MassDEP of the detected concentrations of sodium in drinking water. Notification is required so that individuals who are on sodium restricted diets or who wish to monitor their sodium intake for other reasons will be able to take the amount of sodium in their drinking water into account.

The WWD most recently collected drinking water samples for sodium on May 24, 2017 and provided notification of the results to the required departments in June 2017.  Sodium results are also reported in the annual Consumer Confidence Report (CCR).

Current Sodium in Drinking Water Results 


May 24, 2017 collection date: 66.9 milligram to Liter (mg/L) to 80.3 mg/L.
