No direct connection has been found between hydraulic fracturing and reports of groundwater contamination, according to a study released Thursday by the Energy Institute at The University of Texas of Austin.
The study found that many of the problems linked to hydraulic fracturing are related to common oil and gas drilling operations such as casing failures or poor cement jobs.
Researchers also concluded that many reports of contamination can be traced to above-ground split or other mishandling of wastewater produced from shale gas drilling, rather than hydraulic fracturing per se, said Charles "Chip" Groat, an Energy Institute associate director who led the project.
"These problems are not unique to hydraulic fracturing," Groat said in a statement.
