More than 11.1 million people each day use tap water supplied by Ohio's public water systems. Many more use or benefit from Ohio's extensive ground water resources. Ohio EPA's Division of Drinking and Ground Waters participates in many activities to ensure Ohio's tap water is safe to drink and our precious water resources are protected for future generations.
