Air monitoring of VOCs during hydraulic fracturing operations in Washington County, Pennsylvania

According to the authors, the primary finding of this study was that the operation of a hydraulic fracturing well pad in Washington County did not substantially affect local air concentrations of total and individual volatile organic compounds. Key findings: The results of the continuous monitoring during fracturing and flaring sampling periods for total volatile organic …

Characterizing Air Emissions from Natural Gas Drilling and Well Completion Operations in Garfield County, Colorado

This public and industry sponsored field study by Jeff Collett and colleagues, Colorado State University (CSU), is the first in class to quantify emissions of chemical compounds (air toxics, ozone precursors, and methane) during new well development and to characterize how these compounds are dispersed in the atmosphere downwind of the site. The study was …

Whistleblower: EPA Official Covered Up Methane Leakage Problems Across US Natural Gas Industry

Inspector General has been called by Durham, North Carolina, based group NC Warn to investigate scientific fraud that wasted crucial years in slowing climate crisis while risking safety of workers and communities. NC WARN filed a complaint with the Inspector General of the EPA on June 8, 2016, charging that a high-ranking EPA official connected …

Anthropogenic and natural methane emissions from a shale gas exploration area of Quebec, Canada

Here methane emissions, computed from four potential sources (i. e. 1) groundwater degassing as a result of groundwater abstraction for domestic and municipal uses; 2) groundwater discharge along rivers; 3) migration to the surface by (macro- and micro-) diffuse seepage; 4) degassing of hydraulic fracturing fluids during first phases of drilling.), are reported for an …

Air toxics and birth defects: a Bayesian hierarchical approach to evaluate multiple pollutants and spina bifida

While there is evidence that maternal exposure to benzene is associated with spina bifida in offspring, to our knowledge there have been no assessments to evaluate the role of multiple hazardous air pollutants (HAPs) simultaneously on the risk of this relatively common birth defect. In the current study, we evaluated the association between maternal exposure …
