Early Air Quality Data Near Gas Drilling Site Shows Clear Air

The first four months of air quality data collected near a shale gas drilling well shows the air remains clean. Ohio EPA started collecting data at a gas drilling site located near The Wilds in Muskingum County in April 2012.

The monitor measures particulate matter (PM) pollution, along with various hydrocarbons associated with gas drilling and methane.

The results of the air monitoring revealed no violations of the federal PM2.5 standards, although concentrations of PM10 exceeded the federal threshold of 150 micrograms per cubic meter on June 8, 2012. The single exceedance may have been caused by construction of a nearby road that occurred at that time.

Ohio EPA will continue to add more monitoring equipment and monitor air quality at well sites for at least two years.


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.
