A state environmental report criticizes the Fayette County Water Department for problems at its two water treatment plants.
The 45-page report includes findings of non-certified personnel running the plants, incorrectly signed documents, managers who aren't properly licensed, improper record keeping and broken equipment.
Ted Jackson is drinking water program manager for the Georgia Environmental Protection Agency. He says it's very unusual for two plants in the same county to exhibit serious problems.
The EPA says it's also asking the Georgia secretary of state to investigate the county water department.
Fayette County commission Chairman Steve Brown told TV station WXIA he's upset by the findings and will take steps to fix the problems.
Experts say the water may have tasted bad, but never posed a health risk.
