Each system is tracked in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which requires testing for regulated contaminants, consumer notification of violations, and publication of an annual Consumer Confidence Report.

The records carry 2 distinct EPA contaminant codes: Arsenic, Revised Total Coliform Rule. 7 TRI-reporting industrial facilities are also located within the city limits.
