FRACKING CONTAMINATION "WILL GET WORSE" SAYS ALBERTAN EXPERT
"They'll frack each well up to 20 times. Each time the pressure will shudder and bang the pipes in the wellbore. The cement is hard and the steel is soft. If you do it all the time you are going to break bonds and cause leaks. It's a real major issue. "
Industry spokesmen typically argue that if the drilling hole is properly cased with steel and cemented "the risk of any interaction between drinking water and fracturing fluid is significantly diminished."
