Coliform bacteria

The Revised Total Coliform Rule tracks coliform bacteria — an indicator that disease-causing organisms could be getting into the water.

Read the rule → EPA · Coliform Rule
Ground Water Rule

The Ground Water Rule protects wells and aquifer-fed systems from fecal contamination through source-water monitoring and fixes.

Read the rule → EPA · Ground Water Rule
Lead & Copper Rule

The Lead & Copper Rule requires utilities to test water at customer taps for lead and copper — metals that enter water from pipes and plumbing, not the source. Lead harms brain development in children; no level is considered safe.

Surface Water Treatment

The Surface Water Treatment Rules require utilities using surface water (or groundwater under its influence) to filter and disinfect against microbes like Giardia, Legionella and viruses.
