Study Finds Fracking Not At Fault For Water Contamination

摘要

EAs researchers study hydraulic fracturing, a team led by Thomas Darrah at The Ohio State University has identified a key source of groundwater contamination (labeled 5, center right) caused by faulty well casings, A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source many people may have feared. What's more, the problem may be fixable: improved construction standards for cement well linings and casings at hydraulic fracturing sites.
