The fact is, millions of wells have been drilled all over the United States, not to mention the world, millions(?) have been fracked, and very little of this activity has harmed the ground water being used for human activity. The few horror stories occurred in the early stages of development, decades ago. Even the terrible accident in the Gulf of Mexico two years ago is a rarity and occurred under unique circumstances. Facts are facts. If we can get past the politically-motivated, ideological fear-mongering taking place in the mass media, we'll see that fracking can be done in a safe and productive manner.
