Which Alabama Areas Have the Most Galvanized Pipe Risk?
The 11 Alabama areas with the highest share of confirmed galvanized service lines requiring replacement, out of 11 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.
