A yellow-orange sludge separates during the decontamination process and is safely disposed. Clean fresh water returns to the stream in a continuous flow that dilutes and gradually restores the creek and river to a life-supportive pH balance -- a range of 6.5 to 7.5.

Since treatment began, Muddy Creek and the Cheat River’s water quality has visually and scientifically improved, according to results gathered in recent monitoring tests. Muddy Creek now holds a net alkaline measurement indic-ative of a healthier watershed. Inspectors have spotted brown trout in Muddy Creek for the first time in several decades.

Near Albright, West Virginia, the Cheat River and Muddy Creek watershed were contaminated for decades from acid mine drainage (AMD) originating from long-abandoned mines. The West Virginia Depart-ment of Environmental Protection (WVDEP), and orga-nizations such as Friends of the Cheat, had fought for years to restore these waters to their natural state.

The acidity due to dissolved metals in the AMD severely impacts the stream habitat and imperils the fish, flora and fauna native to the river ecosystem. The water must be treated to raise its pH to neutral. Southwest-ern Energy partnered with the WVDEP on the Muddy Creek Watershed Restoration Project, stepping in to support the AMD water collection and conveyance system that ties into the new T&T treatment facility.

The EPA approved an innovative permitting strategy that allows for contaminated water flowing from sever-al streams to be treated via an in-stream water doser or conveyed through the AMD water collection system to the T&T treatment facility. The water is decontami-nated through a process using lime slurry, polymers and clarifiers to raise the pH and remove the metal substances. It is then returned to the watershed through a single outlet.
