Violations indicate that customers at the highest-exposure locations within the distribution system exceeded the byproduct limits, which poses greater risk than system-average exceedances.

About this data

Rules violated and status in the table are for the whole system, not Stage 2 Disinfectants and Disinfection Byproducts Rule alone.

The New York 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.
