Nearly all public water systems in Pennsylvania contain some type of leaded plumbing materials either in the distribution system or in homes or other buildings.
Optimal corrosion control treatment minimizes the lead concentrations at users' taps. Tap water samples are collected from homes and buildings throughout the community.
