PITTSBURGH (AP) — The gas drilling industry in Pennsylvania is recycling more and more water and one river basin commission now reports drillers there are drawing less freshwater than in the past.

Water use by the natural gas industry in the Susquehanna River Basin peaked at about 3.8 billion gallons in 2011 and that figure declined to about 3.1 billion gallons in 2013, Andrew J. Gavin, deputy executive director of the Susquehanna River Basin Commission, told The Associated Press.
