Ohio EPA Launches New GIS Mapping at Start of Ozone Season

To kick off the beginning of ozone season today, Ohio EPA is launching a new web-based map (Geographic Information System or GIS) application which will enable Ohioans to view real-time air quality data online.

The new website provides interactive geospatial content to users. It is a new and improved online tool that can enable citizens to better understand current air quality. The map shows a color-coded snapshot of the entire state, with more information about the current air quality index at each site available with a click of the mouse.

“Today is the first of several interactive maps we plan to launch to better serve Ohio citizens,” said Ohio EPA Director Scott Nally. “Our goal is to provide important interactive environmental content to Ohioans in a format that is easy to use and understand.”

Ohio EPA worked with the State of Ohio GIS Office to develop this application. The group plans to add more interactive GIS maps dealing with other environmental topics. All Ohio EPA GIS maps can be found online at


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. In the past 40 years, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling. Ohio EPA….40 years and moving forward.
