Mountaintop mining to extract coal will probably be up again next year, as will the issue of fracking that is forcing liquids through pipes to force the expulsion of natural gas. This is another subject that will require more study of the facts on my part. It is my understanding that ". . . using chemicals and water to crack a shale layer once, far below ground, to liberate gas may pose little risk to drinking water supplies near the surface. But fracking the layer multiple times from one well site, which is common, raises the chance that drinking water could be contaminated," and greenhouse gases released into the atmosphere. You can rest assured that I'll closely monitor this legislation with the intent of preventing contaminated water from entering the homes of Tennesseans.
