On paper this system is compliant, but the EPA record shows 56 violations — mostly missed testing or reporting. What isn't measured can't be caught.
The Total Coliform Rule tracks coliform bacteria — an indicator that disease-causing organisms could be getting into the water.

Read the rule → EPA · Coliform RuleThe 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.
