From November, 2012 to June, 2016, Colorado State University (CSU) conducted a study characterizing air emissions from natural gas drilling and well completion operations in Garfield County, Colorado. Garfield County supported and is now making available to the community this first-in-class study, providing the most comprehensive assessment of air toxics, ozone precursors and greenhouse gas emission rates from natural gas well drilling and completion operations to date.

CSU researchers collected air samples from three activities during new well development: drilling, hydraulic fracturing (“fracking”), and flowback. They quantified air emission rates and dispersion of air toxics, ozone precursors and greenhouse gases during each of these processes.

Proposal for data gathering on air emissions in Garfield County to be presented to commissioners

Glenwood Springs, CO - The Garfield County Board of County Commissioners (BOCC) will hear a proposal Monday on a Colorado State University (CSU) scientific study to gather air emissions data surrounding natural gas extraction operations in Garfield County. The commissioners requested data collection by an independent researcher to offer the community scientific data surrounding the impacts of drilling near residential communities. CSU, in collaboration with Air Resource Specialists, Inc., will propose the study as the sixth item on the afternoon agenda in the 1 pm meeting of the BOCC August 20 in the County Administration Building at 108 8th Street, Glenwood Springs.
