The NYT Sunday Magazine has an article entitled, "The Fracturing of Pennsylvania," by Eliza Griswold. http://mobile.nytimes.com/2011/11/20/magazine/fracking-amwell-township.xml
The article tells the story of the natural gas boom by writing about a few people and their lives in Washington County, Pennsylvania. This anecdotal account puts a bright light on both the positive impacts as well as the environmental challenge of natural gas production.
The piece describes the jobs, income, wealth created by gas that have made the lives of many much better. It also describes the substantial health problems of one family that may be the result of drilling pollution possibly coming from a nearby pit that stored drilling wastewater.
The article raises troubling questions about the pit and the use of such pits. It is not clear to me whether the pit that is a focus of the story remains open or has been closed.
Maximizing the benefits of natural gas production and minimizing its impacts by continuously improving regulation and operations must be done. It requires commitment and vigilance.
