The U.S. Environmental Protection Agency is holding the third of four multi-state public information meetings this evening in Canonsburg, Washington County on a proposed study of hydraulic fracturing...fracking...and its impact on drinking water.
Pumping fracking water with chemical additives into the drilled well breaks up the shale and allows the natural gas to be extracted.
The E.P.A. will use comments and suggestions from an independent scientific advisory board and stakeholders to guide the design of the study. Earlier E.P.A. meetings were held in Colorado and Texas.
Listen for reports about this evening's session in Canonsburg from WDUQ's Mark Nootbaar tomorrow on Morning Edition.
