Biggest drops in reported lead pipes since 2025 Q1
These water systems reported the biggest drops in lead and galvanized-requiring-replacement service lines between 2025 Q1 and 2026 Q3, 148,277 lines in total. A drop reflects replacements, or lines confirmed as non-lead after inspection; EPA's data doesn't separate the two, so check each utility's own replacement reports.
