TRANSPORT STORAGE AND DISPOSAL OF FRACKING WASTE
TRANSPORT STORAGE AND DISPOSAL OF FRACKING WASTE

The ,transportation,, storage, and disposal of hydraulic ,fracturing, (“fracking”) waste are regulated under a variety of federal and state laws. Contaminated water, which is fracking ' s largest waste product, is typically (1) treated to remove contaminants and discharged into surface waters, (2) recycled for use on other fracking projects, or (3) injected into specialized wells.
