Recycling fracking water

Fracking, hydraulic fracturing, is one of the most controversial technologies for extracting fossil fuels from within the Earth's crust. Concerns abound regarding its putative effects on the environment not least because of the chemicals involved and the pollution it can generate. Now, researchers at Rice University in Texas are hoping to find a solution to the problem of recycling fracking water. The team has analyzed "produced" water from three underground shale gas formations that have been subject to fracking and tested amounts of total carbon (TC), non-purgable organic carbon (NPOC) and total inorganic carbon (TIC) in the samples. Andrew Barron and colleagues provide details of the implications of their work in the aptly named journal Environmental Science: Processes and Impacts.
