If you want to have a better understanding of the horizontal drilling and hydraulic fracturing processes that are in use in the Fayetteville Shale play and other areas I would suggest you take a look at the document linked below.  There is a lot of incomplete information in newspaper articles and other sources that tends to play on emotional fears rather than science.  The following document is the best single unbiased source of information that I am aware of.
