Disturbing Lead Service Lines

Field work that cuts, bends, or reshapes the service line can release lead. It has been hypothesized that vibrations within a few yards might also be an issue. For example, one peer-reviewed paper suggests surface activities that indirectly vibrate lead service lines could lead to increased lead release. 

More research is needed to know exactly what activities cause lead service lines to vibrate enough to release lead into the water. Affected households should be notified by anyone doing such work near the home’s service line.

Construction Activity:
Construction in the street or yard affecting a service line may affect water quality in the home. Impacted homes should be instructed to flush their service line.

Construction activities exposing lead service lines (LSLs) can disturb the pipe, and other construction activities can affect water quality. Households impacted by construction should be notified that construction could impact water quality, including the possible release of lead in the drinking water.
