Antero Treatment has reached an agreement with environmentalists to monitor for radioactivity and bromide around a northern West Virginia landfill that takes waste from recycled groundwater used in natural gas fracking, according to the Associated Press.

The agreement settles an appeal by the West Virginia Rivers Coalition and West Virginia Highlands Conservancy of the state permit for the landfill. It requires one initial year of monitoring for radioactivity in materials entering the landfill and in groundwater monthly, as well as regular monitoring for bromide and solids in surface water discharges.

The landfill is located adjacent to Antero’s wastewater recycling facility on 447 acres in Ritchie and Doddridge counties.
