FRAC Act Reintroduced in US Congress–
Fails to Address Toxicity of the Blowback Waste Water.

Even IF 100% fresh water was used to hydrofrack these oil wells, the WASTE water returning to the surface would still be a toxic nightmare This Blowback Waste Water oftentimes is “laced with highly corrosive salts, carcinogens like benzene and radioactive elements like radium, all of which can occur naturally thousands of feet underground.”
The toxic blowback water is initially stored in on-site containment ponds which often overflow with heavy rain or simply fail because of inadequate construction. After evaporating the volatile gases, the ultimate destination of this carcinogenic liquid cesspool is a crapshoot. Basically its dispersed back into streams and waterways. Most municipal sewage plants (if Any) are not equipped to detoxify it. At best (or Absolute Worst) it is injected into on-site Class II Injection Disposal Wells under intense pressure. Swarm earthquakes have occurred near such sites in Arkansas and also WV.

“Drillers trucked at least half of this waste to public sewage treatment plants in Pennsylvania in 2008 and 2009, according to state officials.”… – part of which found its way to WV sewage treatment plants.
“most of these facilities cannot remove enough of the radioactive material to meet federal drinking-water standards before discharging the wastewater into rivers, sometimes just miles upstream from drinking-water intake plants.”

“Quotes” are from nytimes.com/2011/02/27/us/27gas.html?_r=1&hp which concerns Pennsylvania. All of which are equally applicable to WV.
