ABSTRACT
Increased application of hydraulic fracturing (i.e., fracking) technology, where water, friction reducers, proppants, disinfectants, surfactants, thickeners, scale inhibitors, corrosion inhibitors, and acids are injected into deep shale formations to extract natural gas, has increased calls from the regulatory community and the public for a closer scrutiny of this activity to ensure that fracking is environmentally safe. The growth in fracking has been unprecedented as vast new shale gas plays are discovered and explored across the world. The tremendous expansion in fracking exploration, and the commensurate increase in groundwater extraction/deep chemical injection, have raised concerns over effects on groundwater supplies and land surrounding the drilling sites. Through due-diligence, liability protection, and/or regulation, baseline sampling is increasingly a standard procedure associated with advancing shale gas exploration wells. A unique challenge in fracking sites baseline sampling is the design of sampling locations and the requisite analyte list, not to mention the interpretation of potential impacts results. This presentation is devoted to discussing the critical aspects of a sampling program, what to test for, and how to provide a risk-based interpretation of analytical results.
