95% of what is said her regarding fracking is incorrect. Go work for a fracking company for a few months and see how it is done, you will see exactly what is in the "contaminated" water. Many companies R &D departments are working on ways to re-use "contaminated" water to frac with multiple times so only a very small percentage of "new" water would be needed per frac. The water table where I frac isn't very deep, the place where the fracking is being done is about 2 miles past the water table and near the top of the wellbore there are 7-8 layers of casing (depends on company), cement and steel between the wellpipe and the ground around it, for the "contaminated" water to impact the water table it would have to bypass all those layers and that isn't going to happen. The oil and gas companies also subsidize the county and city to provide for more water testing just to ensure the public trust, not to mention we do our own testing. We live here and drink the water here, do you really think all the lab and engineering employees would use the local water supply if it were contaminated?
