Study: Ohio’s Rivers Rebound

Ohio EPA this week unveiled the results of its first-ever comprehensive study of Ohio’s largest rivers. The results show tremendous improvements in water quality since the 1980s. See the study results.

The study found 86% of the state’s large rivers are in good to excellent condition, compared to just 18% four decades ago. Soil conservation, wastewater infrastructure, and wastewater treatment are credited as the primary reasons for the improvements. The Mohican River was the only river to show significant decline in water quality due to phosphorus and nutrients from agricultural runoff. 8/2/2023
