Once you pollute the water it is very hard to clean it. Would you want your water contaminated? By limiting pollutants in our water supply protects the over all long term health of our citizens. With what we have learned about toxins in our environment and the damages that toxic contaminants do to our DNA long after these toxins are removed would hopefully strengthen the case for stronger environmental protections of or water supplies. I would think that the health and well being of our citizens and the protection of our resources for future generations would be of the highest importance. The effects of fracking fluids in our confined aquifers we use for drinking,recreation, and agriculture is criminal. The long term neurological and and birth defects from contaminated drinking water will cause birth defects cancer and neurological disorders creating an ongoing liability of tax payers for care of these individuals that suffer from exposure. We have over 12,000 superfund sites that need immediate attention as our citizens suffer with no accountability from the government or regulation from an already impotent EPA that is under funded and politically under constant attack form short sided decisions made by politicians and paid for by corporate interest.
