Fig. 1From: How long do natural waters “remember” release incidents of Marcellus Shale waters: a first order approximation using reactive transport modeling a The numbers of Marcellus Shale water release accidents in Pennsylvania from 2005 to June 8, 2015, with 78% of spills occurred in Northeastern PA. Red spot indicated the location of Bradford County. The yellow numbers are the numbers of spills. b A schematic diagram of 1-dimensional modeling setup. We assume a release point where the Marcellus Shale waters are introduced into the surface water (river) or groundwater (aquifers). The release can occur through spills, discharge, leakage, seepage, among othersBack to article page
