The rapid expansion of gas exploration in Pennsylvania has triggered a demand for more federal oversight over drilling. The New York Times
reported Sunday (July 25) that the EPA is considering looking into issues involving drilling, particularly the practice called fracking, which involves shooting a compound of water, sand and chemicals into the ground to create a gas well. Residents are concerned about the effect of fracking on water supplies and several have complained of contamination. Concerns -- and fear -- is rising in the areas of Pennsylvania where drilling is about to get underway.
