Which Pennsylvania Areas Have the Most Galvanized Pipe Risk?

The 50 Pennsylvania areas with the highest share of confirmed galvanized service lines requiring replacement, out of 236 areas with enough data for a reliable estimate. Galvanized steel isn't lead itself, but a line installed downstream of a lead gooseneck or connector can leach lead particles trapped in its rough interior even after the original lead pipe is gone — federal guidance treats it with the same urgency as a confirmed lead line.
