Before the wastewater is trucked to a remote injection well or processing facility for disposal, wastewater ponds and condensate tanks release volatile organic compounds (VOCs) 24 hours a day, seven days a week. As the VOCs are evaporated and come into contact with diesel exhaust from trucks and generators at the well site, ground level ozone is produced. Ozone plumes can travel up to 250 miles. This is apart and distinct from the carbon pollution issue, by which methane and CO2 from the gas production and combustion process contribute to global warming.
