Fraccing has been used in most wells in the USA since the 1940's. I can't remember a single instance of it affecting the groundwater since it is found far above the depth of almost all the wells drilled. In limestone reservoirs, acid was used in the liquid to open up the natural and induced fractures. The power of the EPA under Obama and the Greens here have introduced a "supposed" problem in an attempt to promote their expensive green energy. It is not and never has been a problem.
