PITTSBURGH (AP) A review by The Associated Press has found that in at least four states that have nurtured the nation's energy boom, hundreds of complaints have been made about well-water contamination from oil or gas drilling.
Pollution was confirmed in a number of them, casting doubts on industry suggestions that such problems rarely happen.
The AP requested recent data on drilling-related complaints from Pennsylvania, Ohio, West Virginia and Texas and found major differences in how the states report such problems. Texas provided the most detail, while the other states provided general outlines.
Pennsylvania received almost 900 complaints in 2012 and 2013 alleging that oil or natural gas drilling polluted or affected private water wells. In recent years Texas recorded 62 complaints, Ohio at least 99 and West Virginia 122.
Some of the complaints are still being investigated.
