The safety of our public water supply is of utmost importance.   The public and all state agencies involved have every right to know what goes into the ground since there is no guarantee that the chemicals will not migrate into unintended areas.  In fact, it is not a matter of IF water will be contaminated by hydraulic fracking fluid, but WHEN.  Even the natural gas industry recognizes that there is a certain failure rate of cement casings that are supposed to contain the fluid.
