the reason why you guys get polluted ground water is because the laws in America are retarded and have no safety standards. I live in a place with 1000's of gas wells and not a single water or ground water issue.. why.. a thing called a secondary casing. something amercunts don't know about or use. it protects any ground water from leeching into the gas well. and it is installed before the main casing to prevent any leeching during drilling
