EPA’s Range Resources Emergency Order

•“The consumer and well owner removed Domestic Well 1 from service…due to rising gas content within the drinking water and concerns with water quality, indoor air quality, and potential explosivity.”

•“The contaminants identified…may present an imminent and substantial endangerment to the health of persons because methane in the levels found by EPA are potentially explosive or flammable, and benzene if ingested or inhaled could cause cancer, anemia, neurological impairment and other adverse health impacts.”

•“EPA has determined that appropriate state and local authorities have not taken sufficient action to address the endangerment…and do not intend to take such action at this time….EPA has determined that this action is necessary to protect the health of persons.”
