Summary Points:
EPA’s central authority to protect drinking water is drawn from the Safe Drinking Water Act (SDWA).
The SDWA requires EPA to set legal limits on the levels of certain contaminants in drinking water.
The Safe Drinking Water Act (SDWA) also requires EPA to protect underground sources of drinking water (USDWs) from contamination caused by underground injection.
-
§1421 provides minimum standards for underground injection.
-
§1422 provides for state primary enforcement authority.
-
§1425 provides for alternative showing of effectiveness of program by state Underground Injection Control (UIC) Programs (Oil and Gas wells only).

Hydraulic fracturing is a common technique used to stimulate the production of oil and natural gas. Typically, fluids are injected underground at high pressures, the formations fracture, and the oil or gas flows more freely out of the formation. Some of the injected fluids remain trapped underground.
A number of these fluids, such as diesel fuel, qualify as hazardous materials and carcinogens, and are toxic enough to contaminate groundwater resources. Read more details in the Oil and Gas Accontability Project's (OGAP) basic primer on hydraulic fracturing.

Fig. 1—In 1947, Stanolind Oil conducted the first experimental fracturing in the Hugoton field located in southwestern Kansas. The treatment utilized napalm (gelled gasoline) and sand from the Arkansas River.
Since Stanolind Oil introduced hydraulic fracturing in 1949, close to 2.5 million fracture treatments have been performed worldwide. Some believe that approximately 60% of all wells drilled today are fractured. Fracture stimulation not only increases the production rate, but it is credited with adding to reserves—9 billion bbl of oil and more than 700 Tscf of gas added since 1949 to US reserves alone—which otherwise would have been uneconomical to develop.
In addition, through accelerating production, net present value of reserves has increased. Fracturing can be traced to the 1860s, when liquid (and later, solidified) nitroglycerin (NG) was used to stimulate shallow, hard rock wells in Pennsylvania, New York, Kentucky, and West Virginia. Although extremely hazardous, and often used illegally, NG was spectacularly successful for oil well “shooting.” The object of shooting a well was to break up, or rubblize, the oil-bearing formation to increase both initial flow and ultimate recovery of oil. This same fracturing principle was soon applied with equal effectiveness to water and gas wells.
In the 1930s, the idea of injecting a nonexplosive fluid (acid) into the ground to stimulate a well began to be tried. The “pressure parting” phenomenon was recognized in well-acidizing operations as a means of creating a fracture that would not close completely because of acid etching. This would leave a flow channel to the well and enhance productivity. The phenomenon was confirmed in the field, not only with acid treatments, but also during water injection and squeeze-cementing operations.
But it was not until Floyd Farris of Stanolind Oil and Gas Corporation (Amoco) performed an in-depth study to establish a relationship between observed well performance and treatment pressures that “formation breakdown” during acidizing, water injection, and squeeze cementing became better understood. From this work, Farris conceived the idea of hydraulically fracturing a formation to enhance production from oil and gas wells.

This book is a comprehensive study of the evolution of the component aspects of drilling technology in Alberta, from the evolution of power sources and drill bit designs to the composition of drilling muds and the use of fishing tools. Included are explanations of the costs and risks of oil well drilling and of the larger issue of industrial technology -- how it evolves and under what conditions. The author draws extensively from original source material such as interviews, photographs, and appendices from both the Glenbow Archives and the Devon-Leduc Petroleum Hall of Fame and Interpretive Centre.

The Day After Tomorrow, (available 2/8/2011) takes readers on a journey to bear witness to the environmental destruction that is currently plaguing our planet; from a forest in West Virginia devastated by mountaintop removal mining, to a region in Florida left in ruins by the phosphate mining industry, J. Henry Fair presents hard evidence that our unchecked consumerism is leading the way in the destruction of our planet, one natural resource at a time.

The type of waste being produced indicates that exploration is still in progress. The overspray at the top is a violation and a danger to any water bodies downhill.
Photographer J Henry Fair is best known for his Industrial Scars series, in which he researches our world's most egregious environmental disasters and creates images that are simultaneously stunning and horrifying.
Mountaintop removal and slickwater drilling for natural gas both have been challenged by experts for the environmental damages that occur. The pollution has been well documented in public testimony and observation and has proceeded without input from peer-reviewed scientific studies, making the people who live near these extraction processes human experiments in methods unproven to be safe in the long term. (Neil Zusman, 2010-11-10.)
During the last two decades, mountaintop removal mining in Appalachia has destroyed or severely damaged more than a million acres of forest and buried nearly 2,000 miles of streams. Leveling Appalachia: The Legacy of Mountaintop Removal Mining, a video report produced by Yale Environment 360 in collaboration with MediaStorm, focuses on the environmental and social impacts of this practice and examines the long-term effects on the region’s forests and waterways.
At a time when the Obama administration is reviewing mining permit applications throughout West Virginia and three other states, this video offers a first-hand look at mountaintop removal and what is at stake for Appalachia’s environment and its people.
Leveling Appalachia: The Legacy of Mountaintop Removal Mining, an e360 video examining the environmental and human impacts of this mining practice, won the award for best video in the 2010 National Magazine Awards for Digital Media. Watch the video.

The Independent Petroleum Association of America sent a letter (pdf) to EPA today highlighting two critics on the list of 82 potential panelists.
"Unfortunately, a number of nominees' past comments betray a strong and unambiguous antipathy toward shale development in general, and hydraulic fracturing in particular," IPAA President and CEO Barry Russell wrote.
The letter singles out two critics -- Theo Colborn and Robert Howarth. It does not give their names, but IPAA's detailed complaints about the two identify them.
Colborn is a Colorado zoologist and pharmacist whose group, TEDX — The Endocrine Disruption Exchange, has sought to document the damage that fracturing can do to water and human health. IPAA said she authored a "white paper" that called for federal regulation of fracturing.
Howarth is a Cornell University professor who issued a three-page draft report in April saying that shale gas production and use may generate as much greenhouse gas emissions as production and use of coal. Russell's letter said it was "riddled with errors."

But how clean is natural gas, really?
The Wilderness Society just released the new science and policy brief Doing it Right: Ensuring Responsible Natural Gas Development on Our Public Lands to address the question: How clean is natural gas?
Unfortunately, as the brief reveals, natural gas is not the panacea that its promoters would have us believe. Consider these facts:
Natural gas is only 30 to 50 percent cleaner burning than coal.
Natural gas is still a fossil fuel and our current use of it contributes about 20 percent of U.S. greenhouse gas emissions.
The processing, infrastructure, and burning of natural gas releases methane, a greenhouse gas 30 times more potent than carbon dioxide in terms of its heat-trapping ability.
Methane emissions from natural gas infrastructure are the third largest source of methane emissions in the United States, according to a September 2009 study by the Congressional Research Service.
Smog, or ground level ozone, has risen tremendously in areas with high levels of natural gas development. For example, in Sublette County, Wyo., after more than 3,100 gas wells were drilled in the past 10 years, ground-level ozone levels increased from background levels to those exceeding the Los Angeles basin in the winter of 2008.
