Sure it burns "clean" (er). Sure it adds jobs which we need very much these days. As someone who lived in Colorado, it sure has messed up the groundwater, local wells that can be lit with a match, major sludge pits and who knows what the impact will be 10, 20,100 years from now. Is it true that this procedure has been exempted from many USEPA standards? If this practice is allowed to continue in and around ground water sources that supply major population centers no one knows what the future holds. Check it out for yourself and then decide if this is something you want to support or not.
