We strongly recommend using a certified water filter to reduce exposure to these contaminants.

EPA records 2 health-based violations for CITY OF BOERNE that began after its latest compliance result on file (Sep 2024): Maximum Contaminant Level Violation, Average (TTHM), 2 violations, the first beginning on October 1, 2024 and the latest on April 1, 2025.
