CANTON, Pa. -- A natural gas company has suspended "fracking" at all of its wells throughout Pennsylvania until it figures out the cause of a spill in the northern part of the state.
Chesapeake Energy Corp. said Thursday that crews have significantly reduced the flow of chemical-laced water from its out-of-control well near Canton in Bradford County.
Spokesman Brian Grove says that the exact cause of Tuesday night's breach is unknown, but that it's located in a wellhead connection.
Thousands of gallons of drilling fluids were spilled. They escaped containment, crossed over farm fields and went into a stream.
Grove says initial testing of area waterways has shown "minimal impact, if any."
Fracking is short for hydraulic fracturing and involves injecting chemicals into the ground to release natural gas.
