The Environmental Protection Agency has warned residents of Pavillion, Wyoming not to drink their tap water because of contamination being blamed partly on the use of hydraulic fracturing, or hydrofracking, to mine for natural gas nearby. ProPublica reports:
The federal government is warning residents in a small Wyoming town with extensive natural gas development not to drink their water, and to use fans and ventilation when showering or washing clothes in order to avoid the risk of an explosion.
The announcement accompanied results from a second round of testing and analysis in the town of Pavillion by Superfund investigators for the Environmental Protection Agency. Researchers found benzene, metals, naphthalene, phenols and methane in wells and in groundwater. They also confirmed the presence of other compounds that they had tentatively identified last summer and that may be linked to drilling activities.
“Last week it became clear to us that the information that we had gathered” “was going to potentially result in a hazard — result in a recommendation to some of you that you not continue to drink your water,” Martin Hestmark, deputy assistant regional administrator for ecosystems protection and remediation with the EPA in Denver, told a crowd of about 100 gathered at a community center in Pavillion Tuesday night. “We understand the gravity of that.”
Not all of the pollutants found in the water supplies are associated with hydrofracking, some are agricultural in nature. An earlier report from ProPublica notes that the natural gas wells in the area use hydrofracking, the same process planned for thousands of acres of public and private land in Michigan.
The process of hydrofracking requires using large amounts of water and chemicals — up to five million gallons for a single well — to fracture shale deposits and release the natural gas they contain. More than 600,000 acres of public and private land in Michigan is slated to be used for this same process.
