A new study may have a solution for both acid mine drainage and natural radioactivity in hydraulic fracturing – fracking – wastewater that can be found in 'flowback fluid.' In hydraulic fracturing, water is injected at high pressure down wells to crack open shale deposits buried deep underground and extract the natural gas trapped within the rock. Some of the water can flow back up through the well, along with natural brines and the natural gas. read more
