A new technology known as hydraulic fracturing—or fracking—has made it possible to extract natural gas from "unconventional" resources trapped in rock formations thousands of feet underground. While this can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment.Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on. There are several evidences that I found to address the problem of water quality and quantity caused by drilling and hydraulic fracturing.

First of all, there have been reports of flammable methane migrating into local drinking water supplies, and spills of drilling fluids and contaminated water are believed to have killed livestock, fish and other aquatic life in ponds and streams. Fracking operations can also require several million gallons of water, which must be withdrawn from nearby wells, lakes, rivers or industrial or municipal systems, leaving insufficient water for other important uses.

Moreover, Shortly before midnight, April 19, 2011, residents near Leroy Township, Pennsylvania, were jolted by a frenzy of activity. A natural gas well on a nearby farm had blown out, spewing thousands of gallons of toxic water and chemicals over fields and into a tributary of the Susquehanna River. Nearby families evacuated as first responders scrambled to rebuild a failed earthen berm and mobilize a fleet of vacuum trucks to keep the liquid from spreading. No one was quite sure how to stop the roughly 10,000 gallons of toxic wastewater that ultimately spilled, so, as the waster rushed out, local officials waited 11 hours for a specialized team to fly in from Texas. The disaster was one of at least four major spills and accidents that have struck Pennsylvania during the past several years in the
