What the frack?
Don’t be fooled
Headlines in the New York Times and other news media about the EPA’s long-awaited study on the impacts of fracking on drinking water are another tragic case of not looking beyond the timid agency’s spin.
Despite the lack of new substantive data and the limited scope of the study, the EPA did find instances of water contamination and outlined the areas where this could happen in the fracking process.
Rather than seriously undertaking its mission, the EPA’s headline and conclusions in the study reflect the agency’s on-going narrative about the safety of fracking. The agency asserted in the report on the study that there were no “widespread, systemic impacts on drinking water resources.” They based this outrageous conclusion on the limited industry controlled data and analysis that was included in the poorly designed research project.
The multi-million dollar study did not answer the fundamental questions about the pollution of water from hydraulic fracturing. The oil and gas industry pressured the agency in the design of the study, narrowing its scope and focusing it on theoretical modeling conducted by researchers that often conduct research favorable to the industry.
In a shocking display of the power of oil and gas interests, they successfully blocked the agency from gathering data from direct monitoring of fracking operations. Rather than demanding that companies like Exxon (the largest fracker in the U.S.) or Chesapeake allow them to monitor water wells near fracking operations, the EPA caved to industry pressure.
For the study to be meaningful, the agency needed to conduct baseline water testing at prospective wells that would provide a snapshot of water quality before fracking and that would be retested after a year or more after oil or gas production began.
What information does it provide?
Geoffrey Thyne, a geochemist and a member of the EPA’s 2011 Science Advisory Board, a group of independent scientists who reviewed the plan for the study, remarked on the failure of its design:
“This was supposed to be the gold standard. But they went through a long bureaucratic process of trying to develop a study that is not going to produce a meaningful result.”
Yet even with the study’s poor design and the deceptive headlines, the 600-page document does include concrete examples that fracking does indeed contaminate groundwater resources, a fact already confirmed by numerous studies based on existing scientific data.
The study confirmed cases of water contamination with five after-the-fact, or retrospective, case studies, each focused on a community where residents have complained about water problems for years. This embarrassingly limited review of the impacts from spills and releases, water withdrawals, and issues with waste disposal provide proof that fracking negatively impacts our water resources. They included:
- Drinking water monitoring wells had “chemicals or brine” from a blowout that occurred during fracking operations in Killdeer, ND.
- “Up to nine out of 36” wells considered in a Northeastern Pennsylvania case study “are impacted by stray gas (methane and ethane) associated with nearby hydraulic fracturing activities.”
- In Southwestern PA, wastewater pits and other storage sites caused chloride contamination. Regarding stray hydrocarbon gas found in domestic water wells, the EPA determines it was from shallower gas formations, not the targeted shale formation, but whether nearby drilling through the shallower formations led to such contamination remains unanswered.
- At the same time as hydraulic fracturing operations in Wise County, TX, two water wells were impacted by increased presence of brines.
