Water Well & Aquifer Contamination
- The oil and gas industry claims that oil and gas drilling has never contaminated one water well.
- The Colorado government’s COGCC website has lots of documented contaminated water wells, probably 100s. The form used for these contaminated well reports, which list the contaminates, is form 19.

- In a Duke University study sixty wells were tested. The water samples taken closest to the gas wells had on average 17 times the levels of methane detected in wells further from active drilling.
- The EPA suspects hydraulic fracturing in a shallow natural gas well in Wyoming contaminated a town’s drinking water. After three years of study, the agency concluded that chemicals found in the aquifer and in individual wells were consistent with those used in hydraulic fracturing.
- EPA whistle blower, Wes Wilson, stated the EPA failed to protect underground sources of drinking water.
- 13 Pennsylvania families launched a law suit claiming the fracking process contaminated their water.
- 60% of well casings fail within 20 years and eventually all fail since they are made of steel and concrete. This statement from Cornell Professor Ingraffea is based on his analysis using Pennsylvania statistics and “From Mud To Cement – Building Gas Wells”, Autumn 2003, Schlumberger’s Oil Field Review, Vol 15, Issue 3. For more details contact Dr. Ingraffea at Cornell University.
- Ingraffea has been a principal investigator on research and development projects ranging from the National Science Foundation, National Aeronautics and Space Administration (NASA) through Schlumberger, Gas Research Institute, Sandia National Laboratories, Association of Iron and Steel Engineers, General Dynamics, Boeing and Northrop Grumman Aerospace. Having been an industry insider for so long, he is a formidable opponent of anyone who dares to go against him in a debate about high-volume hydraulic fracturing.
- A new peer-reviewed scientific study has concluded that fracking chemicals injected into the ground could migrate toward drinking water supplies far more quickly than some experts had previously predicted. Abrahm Lustgarten of Propublica reports on the significance of the study’s findings here:
- Scientists have theorized that impermeable layers of rock would keep the fluid, which contains benzene and other dangerous chemicals, safely locked nearly a mile below water supplies. This view of the earth’s underground geology is a cornerstone of the industry’s argument that fracking poses minimal threats to the environment.
But the study, using computer modeling, concluded that natural faults and fractures in the Marcellus, exacerbated by the effects of fracking itself, could allow chemicals to reach the surface in as little as “just a few years.”
“Simply put, [the rock layers] are not impermeable,” said the study’s author, Tom Myers, an independent hydrogeologist whose clients include the federal government and environmental groups.
Fracking Water Requirements
- Using an estimated 2.5-3.5 million gallons of fresh water per well with as many as 28-30 wells per pad, and 10 “fracks” per well, this adds up to about 67-105 million gallons of fresh water per pad. What You Need to Know About Natural Gas Production
- Western Resource Advocates report shows that fracking in Colorado uses enough water to supply 166,000 to 296,000 people for a year for household use. Everything You Need to Know About Water and Community Impacts from Hydraulic Fracturing.
- Instead of exposing their citizens to the damages of modern drilling and fracking, countries around the world should enact national bans on the practice and invest aggressively in the deployment of energy efficiency and renewable energy technologies. Fracking – The New Global Water Crisis.

- Over the past several decades, U.S. industries have injected more than 30 trillion gallons of toxic liquid deep into the earth, using broad expanses of the nation’s geology as an invisible dumping ground. No company would be allowed to pour such dangerous chemicals into the rivers or onto the soil. But until recently, scientists and environmental officials have assumed that deep layers of rock beneath the earth would safely entomb the waste for millennia. There are growing signs they were mistaken.Records from disparate corners of the United States show that wells drilled to bury this waste deep beneath the ground have repeatedly leaked, sending dangerous chemicals and waste gurgling to the surface or, on occasion, seeping into shallow aquifers that store a significant portion of the nation’s drinking water.
