Of the 40, 34 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
