About this data
A system is counted once if any of its violations in the past three years involved Long Term 2 Enhanced Surface Water Treatment Rule (LT2), including monitoring and reporting lapses.

The Louisiana records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
