The Dangers of Gas Drilling: How Unconventional Gas Threatens our Water, Health, and Climate
A section of a larger publication by Desmogblog.com entitled ‘Fracking the Future’.
“You don’t want a situation like we have with BP in the Gulf Coast. You don’t want an oil company saying ‘don’t worry.’ Instead, you want these effects tested carefully, in well established circumstances.” – Dr. Daniel Botkin, PhD Ecologist and Professor Emeritus, University of California, Santa Barbara
Fractured Communities: Case Studies of the Environmental Impacts of Industrial Gas Drilling
“This report describes hundreds of case studies demonstrating that industrial gas drilling, including horizontal drilling using high-volume hydraulic fracturing, results in significant adverse environmental impacts. These impacts result from changes in land use, roadbuilding, water withdrawals, improper cementing and casing of wells, over-pressurized wells, gas migration from new and abandoned wells, the inability of wastewater treatment plants to treat flowback and produced water, underground injection of brine wastewater, improper erosion and sediment controls, truck traffic, compressor stations, as well as accidents and spills.”
Natural Gas operations from a Public Health Perspective
From the September 4th, 2010 ‘International Journal of Human and Ecological Risk Assessment’ by Theo. Colborn, Ph.D. (TEDX, The Endocrine Disruption Exchange)
“ABSTRACT – In the 1990s, the U.S. rush to become energy self-sufficient led to rapid expansion in acreage and intensity of natural gas operations across the western U.S. Modern technology to recover natural gas depends on undisclosed amounts of toxic chemicals and the release of combustion materials and other gases that may pose immediate and long term hazards to human health, water and air. We compiled a list of products and chemicals used in natural gas operations, searched the literature for their health effects, and categorized them according to standard toxicological categories. From this we created a profile of possible health effects based on the number of chemicals associated with each category. We demonstrated that toxic chemicals are used during both the fracturing and drilling phases of gas operations, that there may be long term health effects that are not immediately recognized, and that waste evaporation pits may contain numerous chemicals on the Superfund list. Our findings show the difficulty of developing a water quality monitoring program. To protect public health we recommend full disclosure of the contents of all products, extensive air and water monitoring, a comprehensive human health study, and regulation of hydraulic fracturing under the Safe Drinking Water Act.”
Insufficient evidence Hydrofracking is safe, says Dr. David Duggan, President of Onondaga County Medical Society
“The Onondaga County Medical Society wishes to express its strongly held opinion that there is insufficient scientific evidence available to assure that the process of hydrofracking to enhance natural gas production is safe. Because of the potential for significant health problems arising from exposure to unknown chemicals in drinking water and through agricultural uses of contaminated water, we believe that proposals for hydrofracking in Upstate New York should be made contingent upon the provision of sufficient scientific evidence to ensure that the public’s health is protected.”

Long Term Cumulative Community Impact of the Massive Industrialization of High Volume Horizontal Hydrofracture Shale Gas Drilling
A detailed document highlighting numerous papers and videos of scientists and professionals discussing horizontal hydrofracturing. Some of the highlights include:
- Fracking and how it’s different from, and more risky than, “conventional” drilling
- Rebuttal of industry arguments favoring shale gas extraction
- Social effects on communities where a huge number of shale gas wells have been drilled – three-year study of Bradford, PA
- Financial analysis of shale gas reserves, economic viability, and the drilling treadmill.

Hydraulic Fracturing 101
“Hydraulic fracturing – What it is:
Geologic formations may contain large quantities of oil or gas, but have a poor flow rate due to low permeability, or from damage or clogging of the formation during drilling. This is particularly true for tight sands, shales and coalbed methane formations.
Hydraulic fracturing (aka fracking, which rhymes with cracking) stimulates wells drilled into these formations, making profitable otherwise prohibitively expensive extraction. Within the past decade, the combination of hydraulic fracturing with horizontal drilling has opened up shale deposits across the country and brought large-scale natural gas drilling to new regions.”

New Solutions Study: Impacts of Gas Drilling on Human and Animal Health.
“ABSTRACT - Environmental concerns surrounding drilling for gas are intense due to expansion of shale gas drilling operations. Controversy surrounding the impact of drilling on air and water quality has pitted industry and lease – holders against individuals and groups concerned with environmental protection and public health. Because animals often are exposed continually to air, soil, and groundwater and have more frequent reproductive cycles, animals can be used as sentinels to monitor impacts to human health. This study involved interviews with animal owners who live near gas drilling operations. The findings illustrate which aspects of the drilling process may lead to health problems and suggest modifications that would lessen but not eliminate impacts. Complete evidence regarding health impacts of gas drilling cannot be obtained due to incomplete testing and disclosure of chemicals, and nondisclosure agreements. Without rigorous scientific studies, the gas drilling boom sweeping the world will remain an uncontrolled health experiment on an enormous scale.”
