A recent study from the University of Texas at Austin’s Energy Institute found “no evidence” of groundwater contamination resulting from hydraulic fracturing. Concluded lead author Charles Groat: “We found no direct evidence that hydraulic fracturing itself – the practice of fracturing the rocks – had contaminated shallow groundwater.”
Here is the list of the UT Energy Institute’s overview of findings:
- Researchers found no evidence of aquifer contamination from hydraulic fracturing chemicals in the subsurface by fracturing operations, and observed no leakage from hydraulic fracturing at depth.
- Many reports of groundwater contamination occur in conventional oil and gas operations (e.g., failure of well-bore casing and cementing) and are not unique to hydraulic fracturing.
- Methane found in water wells within some shale gas areas (e.g., Marcellus) can most likely be traced to natural sources, and likely was present before the onset of shale gas operations.
