ERT to Perform Environmental Restoration Services at Crab Orchard

ERT has been awarded a task order under the Louisville ERSC MATOC to perform Environmental Restoration Services (ERS) at the Explosives/Munitions Manufacturing Areas at the Crab Orchard National Wildlife Refuge (CONWR) in Marion, Illinois. The CONWR is part of a former Ordnance Plant that operated in the 1940s. The objective of this work is to replace a pipe and berm with a low water crossing that is constructed of rip rap that will still allow high water events to flow through from the settling pond.
