"Recently retired Environmental Protection Agency environmental engineer Weston Wilson is best known for criticizing his employer’s 2004 finding that hydraulic fracturing poses little or no risk to domestic groundwater.
Now, the Denver EPA whistleblower is encouraged by the agency’s interest in studying the natural gas development procedure’s potential impacts on air quality as well.
“I’m proud of EPA now,” not just for undertaking the study, but indicating it may expand the study’s reach beyond water, Wilson said.
His position puts him at odds with the oil and gas industry. At a Denver EPA meeting this summer, several industry representatives argued the study should be limited, as directed by a congressional committee, to the relationship between fracturing and groundwater. “And certainly not air quality,” as Kathleen Sgamma of the Western Energy Alliance put it."
