Human health risk assessment of air emissions from development of unconventional natural gas resources – by Lisa M. McKenzie, Roxana Z. Witter, Lee S. Newman, John L. Adgate, Colorado School of Public Health, University of Colorado, Anschutz Medical Campus, Aurora, Colorado, USA

“Residents living ≤1/2 mile from wells are at greater risk for health effects from NGD than are residents living >1/2 mile from wells. Subchronic exposures to air pollutants during well completion activities present the greatest potential for health effects. The subchronic non-cancer hazard index (HI) of 5 for residents ≤1/2 mile from wells was driven primarily by exposure to trimethylbenzenes, xylenes, and aliphatic hydrocarbons. Chronic HIs were 1 and 0.4. for residents ≤1/2 mile from wells and >1/2 mile from wells, respectively. Cumulative cancer risks were 10 in a million and 6 in a million for residents living ≤1/2 mile and >1/2 mile from wells, respectively, with benzene as the major contributor to the risk.”

The Crisis In Oil & Gas Regulatory Enforcement States Are Betraying The Public By Failing To Enforce Oil And Gas Development Rules

“This report shows that states across the nation are betraying one of the basic agreements between government and the governed: to enforce the law. That betrayal feeds into the growing lack of confidence that government should be about equal treatment and not about financial or political clout.

This betrayal of the public interest also severely weakens state claims that they can protect the public from the impacts of the shale boom. A rule – even an improved rule – on the books means little if an oil or gas company knows that it can be ignored with little or no consequence.”

“Taking the Handle Off the Fracking Pump:  Human Rights and the Role of Public Health Inquiry in an Age of Extreme Fossil Fuel Extraction”  (Sandra Steingraber, PhD) 

“Exposures to this kind of air pollution has demonstrable links to asthma, stroke, heart attack, cancers, and preterm birth. As the shale gas boom sweeps eastward into densely populated areas already struggling with air pollution and whose rivers provide drinking water for millions, public health inquiry is desperately needed to explicate the cumulative health impacts of fracking and to quantify their economic costs.” (SOURCE: Physicians Scientists and Engineers for Healthy Energy Conference Lectures)

Unconventional Natural Gas Development and Infant Health: Evidence from Pennsylvania

“The results suggest that exposure to NGD before birth increases the overall prevalence of low birth weight by 25 percent, increases overall prevalence of small for gestational age by 17 percent and reduces 5 minute APGAR scores, while little impact on premature birth is detected.”

Impacts of Gas Drilling on Human and Animal Health

NEW SOLUTIONS, Vol. 22(1) 51-77, 2012, Scientific Solutions, MICHELLE BAMBERGER & ROBERT E. OSWALD

“Communities living near hydrocarbon gas drilling operations have become de facto laboratories for the study of environmental toxicology. The close proximity of these operations to small communities has created a variety of potential hazards to humans, companion animals, livestock and wildlife.”

One Colorado Town Takes the Time to Study the Impacts Before Drilling

The Battlement Mesa Health Impact Assessment (HIA)

This document, commissioned by the Garfield County Board of County Commissioners, provides objective information and evidence-based recommendations to increase the potential health benefits of natural gas drilling in the Battlement Mesa PUD, while minimizing potential health risks. (Read how this document came about through a citizen action group such as ours)

Air Quality Studies:

NOAA-led study: Colorado oil and gas wells emit more pollutants than expected – National Oceanic and Atmospheric Administration

CU Denver study links fracking to higher concentration of air pollutants – The Denver Post

Read this article from The Dallas Morning News about the widespread evidence of emissions: Most Barnett Shale facilities release emissions.
