Public water systems (PWSs) are regulated by the Ohio EPA Division of Drinking and Ground Waters (Ohio EPA DDAGW). Public water systems use either a ground water source, a surface water source or a ground water under the direct influence of surface water source. In Ohio, around 4,800 public water systems serve approximately 11 million people daily.

EPA sets legal limits on over 90 contaminants in drinking water. The legal limit for a contaminant reflects the level that protects human health and that water systems can achieve using the best available technology. EPA rules also set water-testing schedules and methods that water systems must follow.
