Water Quality Programs

The Division of Surface Water (DSW) includes several programs that support the Clean Water Act’s “fishable, swimmable” goals for all surface waters in Ohio. These programs assess the quality of the surface waters, set standards for protection of the waters and establish plans to bring impaired waters back into attainment with water quality goals. See the links to individual program pages on the right.
