The Sewage Sludge Action Network has joined the Frack-Free NC Alliance. “Frack-Free NC” is a network of grassroots organizations who believe that shale gas development using “fracking” and horizontal drilling cannot be done without bringing harm to our waters, land, air, communities and public health. There are cases where fracking fluids are being ‘treated’ at waste water treatment plants, i.e. where the waste byproducts are introduced into sewage sludge. Fracking fluids contain upwards of 800 chemicals, many of which are carcinogenic.
