Elevated levels of lead in water can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The Westford Water Department does test for lead in the water (the most recent results were well below the required limits) and is responsible for providing safe, high-quality drinking water. However, we cannot control the variety of materials used in plumbing components.
Additionally, the Water Department’s corrosion control program functions to reduce corrosion of the metal piping water travels through by raising the naturally corrosive pH of area groundwater to a slightly alkaline and non-corrosive level. This program has been effective at reducing lead concentrations in the drinking water.
When your water has been sitting for several hours (such as overnight), you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using the water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 800-426-4791 or at
