Im split on this. Every fracking operation Ive known has got a mass of release products in its discharge water. (They will pump anywhere from 3 to 9 million gallons into the deep drill holes under hiigh pressure) The fracturing then occurs as the pressure mounts past a specific point for that rock body. Most of the fracking is being done in sandstone than shale beds because they can propogate more tiny cracks that will then carry the gas.
The products in the fracking water is already made up as a chemical mix in a water base. It uses organics, soaps, metal carbonates and stuff like antacids. When the fracking liquid is pumped back out, it is even nore laden with everything that does include radiaoactive elements from the rock itself. The rock units in PA and NY arenaturally full of Uranium and Thorium (Im not sure about plutonium because the natural isotope for plutonium is rare and its needs beryllium to be incontact with uranium so that the decay product is Pu--So, I dont know about that one. (If its true,Id be more concerned because Pu is more of an environmental concern because it generates alpgha [particles which are a wek radioactive compound but can cause tumors in your snot surfaces like lungs and nasal cavities)
Nobody seems to be doing anything about it until recently. PA has just stopped the collection and dumping of fracking fluids until the drillers come up with some method to better treat and dispose. This is a good step . Im not too happy of the head in the sand attitude like New York where they seem to be banning drilling altogether.
Ae need this gas to get an alternative fuel economy rolling. To just stop it is stupid. However, the state of PA DOES NOT TAX the drillers to help defray the costs of cleanup. PA has some of the most fucked up streams fromall thepast coal mining and now we are giving the gas drillers a free fuckin ride.
But we do need the gas.
1tax em(Its called a severance tax,)
2Make the drillers get staffers on employ who know about environmental wengineering(Most companies that used to be able to do the research and design have morphed into "commodity services" since the 1990's)
3MAke em plan and build treatment facilities
