Louisville Environmental Services AI 2117 Remediation

Work consists of the construction (injection) of a 150-foot long BOS-200® Barrier Wall in the subsurface along the top of the Ohio River bank and perpendicular to the groundwater plume, to create a permeable treatment barrier between the area of impacted groundwater and the Ohio River. The barrier wall includes a total of 69 injection points and is divided into four sections with different lengths, and each area having a different injection design. Two of the wall sections include 3 rows of injection points with two injection depth intervals (33-42 feet and 43-48 feet). The other two sections include four rows of injection points with three injection depth intervals (33-42 feet, 43-48 feet, and 49-53 feet). Tasks to be performed include: preparation of a project work plan and health and safety plan, acquisition of any required permits/approvals, installation of erosion and sediment control features, limited clearing of brush and tree limbs to access the work area while minimizing disturbance of surface soils, furnishing of all materials required, installation of the BOS-200® Barrier Wall, and restoration of the work area.
