KEMRON-Arrowhead JV (KAJV), a joint venture between Lenexa, KS-based Arrowhead Contracting, Inc. and Atlanta, GA-based KEMRON Environmental Services, Inc. was selected through a competitive procurement for award of the Cherokee County Superfund Site Remediation of OU3 and OU7 Residential Soils project. The Cherokee County Superfund site is a former mining area in southeast Kansas, part of a larger regional mining area known as the Tri-State Mining District. It covers about 115 square miles. Over 100 years of widespread lead and zinc mining created piles of mine tailings covering more than 4,000 acres. The mine tailings contaminated surrounding properties and groundwater with lead, zinc, and cadmium. Under the contract, KAJV will remediate and restore approximately 350 residential properties throughout Baxter Springs and Galena, KS, over a four-year period. KAJV will also manage a local soil repository designated by EPA to receive the mine waste material. Repository tasks will include waste stabilization, minimizing future settlement, and covering the existing mine waste piles to ensure slope stability and minimize erosion.
The project will be carried out as a task order under the EPA CLIN - 2 Remediation Environmental Services ID/IQ Program. The task order will be administered by EPA Region VII. The project value is approximately $19M, contingent upon final quantities and option year funding.
