Gas drilling companies such as Halliburton say the gas drilling technique known as hydraulic fracturing, or “fracking,” is safe, but opponents contend it pollutes groundwater with dangerous substances. Now, new evidence has emerged possibly linking natural gas drilling to groundwater contamination. ProPublica journalist Abrahm Lustgarten reports federal officials in Wyoming have found that at least three water wells contain chemicals used in hydraulic fracturing.
Pavillion, WY, August 14, 2009 - This week U.S. Environmental Protection Agency told a group of over 70 that initial investigations found 11 of 39 tested drinking water wells were contaminated. Among the contaminants are toxics used in oil and gas production.
As part of a Superfund investigation, EPA began sampling in March 2009 in the Pavillion, WY area in response to multiple landowners concerns about changes in water quality and quantity following EnCana's increased gas development in the area. Wyoming Department of Environmental Quality (WDEQ) and EnCana had continually assured Pavillion residents that there was no evidence of hydrocarbons or toxic chemicals in their drinking water wells.
"Our families and neighbors are experiencing everything from miscarriages and rare cancers to central nervous system disorders, seizures, and liver disease" said John Fenton of Pavillion Area Concerned Citizens, a citizens group formed to address oil and gas contamination.
EPA confirmed the presence of 2-butoxyethanol (2-BE), a known constituent in hydraulic fracturing fluids, in three wells. This is the same chemical that was documented in the water well of Laura Amos, a Colorado landowner, after nearby wells were hydraulically fractured by EnCana. EPA reported that other water contamination, in the Pavillion wells, included methane, as well as adamantanes (a form of hydrocarbon) and six other chemical compounds of concern.
In 2001 EnCana's fracturing operations in Silt, Colorado were linked to methane and other contamination of Ms. Amos' nearby water well. Amos was unable to test immediately for chemical constituents related to hydraulic fracturing as she was unable to identify what chemicals were in EnCana's drilling products. In 2003 Ms. Amos was diagnosed with a rare adrenal cancer and she later discovered that 2-BE had been used in EnCana's fracking products. According to Dr. Theo Colborn at The Endocrine Disruption Exchange, known health effects of 2-BE include elevated numbers of combined malignant and non-malignant tumors of the adrenal gland, kidney damage, kidney failure, toxicity to the spleen, the bones in the spinal column and bone marrow, liver cancer, anemia, female fertility reduction, and embryo mortality.
As a result of the EPA's findings, residents in the Pavillion area are now calling for a halt to EnCana's fracturing operation. "It's very concerning that we are finding known fracturing products and hydrocarbons in our citizens' water wells," says John Fenton. "We'll await EPA's determination as to what is the cause of this contamination. However, in the mean time, we are asking EnCana to ensure no more fracturing occurs in the area."

That sure sounds a lot like hydraulic fracturing. In 2005, at the urging of Dick Cheney, former Halliburton CEO, Congress exempt fracing from the Safe Drinking Water Act (SDWA) as part of the Energy Policy Act of 2005. It's way past time to repeal that exemption! I'll have a link up later to resolutions your group, municipality, county, etc. can adopt asking our legislature to remove the exemption.
But, there's no need to worry because the industry tells us that hydraulic fracturing is perfectly safe and never, ever contaminates any water and it's really precise except for when it's imprecise.
UPDATE: I understand that the death toll is now up to 30 but that's unconfirmed.
An animal lies near the drilling site where at least 18 cows died TuesdayeveningDuBose said he and Canady captured on video a yellowish-green substance that was spewing into the air and falling onto the ground. Caddo deputies also said a yellowish-green substance was covering the ground and a Chesapeake employee said it was a chemical used in the fracing process.
...investigators found white, milky puddles here and there both on the well site and in a 400 square-yard area just inside the pasture.
...
The livestock died Tuesday near rain puddles in their pasture, said a Caddo Parish sheriff's spokeswoman, Cindy Chadwick. Local residents reported the cattle were foaming at the mouth, bellowing and had bleeding tongues.

"The cows' tongues hanging, bleeding off front and back, foaming at the mouth and bellowing" she said.
William Dubose said he captured video of yellowish-green fumes that smelled like a combination of antifreeze and petrochemical.
Scientists studying residents living in a 1970s era housing development built atop a retired oil field waste pit found an extraordinarily high incidence of lupus, an autoimmune disease. Researchers calculated that the rate was 30 to 99 times higher in people living in this six-block area of Hobbs, NM, than what would be expected in the general population.Drink up! Eat up!
