Baton Rouge, LA
SEMS was contracted to execute a Corrective Measure Workplan to install institutional controls for a Bauxite Mud Lake (Red Mud Area). The Red Mud Area is approximately four acres and was purchased for possible use as a future landfill. The area was the result of an ALCOA levee breach circa 1942. The plan included ground water monitoring to determine if leaching of constituents from the red mud or other materials in the area have occurred over the years impacting groundwater. The red mud in this location is a by-product from the aluminum production process. The plan included installation of monitoring wells and sampling activities. The Red Mud Area is considered a solid waste management unit and will be closed as such. The project included the placement of in-place soil cap/cover over the exposed bauxite red mud.
