Division of Surface Water

Ensures compliance with the federal Clean Water Act and works to increase the number of water bodies that can safely be used for swimming and fishing.

We issue permits to regulate wastewater treatment plants, factories and storm water to reduce the impact of pollutants. We develop comprehensive watershed plans aimed at improving polluted streams. We sample streams, lakes and wetlands, including fish, aquatic insects and plants, to determine the health of Ohio’s surface waters.
