Last year MDN endorsed a proposal put forth largely by anti-drillers–a proposal that tracers be used in fracking fluids to put to rest, once and for all, the silly notion that frack fluids are rising from the depths to “contaminate” water aquifers (see Using Tracers in Fracking Fluid – Ready for Prime Time?). Using tracers, or unique “fingerprints” that positively identify fluid as coming from shale drilling, can be used to check nearby streams and rivers to ensure such fluids have not somehow been released into the environment after they’ve come back to the surface for disposal by recycling or injection well. Our only concern was/is that the science is solid. Yesterday, the National Science Foundation announced researchers (using NSF and Park Foundation grant money) have field tested and pronounced they now have a solid solution…
