Environmental Services, Confidential Client, West Virginia and Ohio

KEMRON performed operation and maintenance (O & M) and other investigation and remediation activities at large chemical manufacturing plants and waste management sites located in Ohio and West Virginia. Activities were conducted under RCRA and CERCLA guidelines. The following provides highlights of select projects completed at these facilities.

O&M. KEMRON provided O&M services for a large chemical plant waste disposal area in West Virginia. Multiple waste disposal units including RCRA surface impoundments, solid waste management units and drum burial sites were included in this site. Project remediation activities included the O&M of a 12-well groundwater and product recovery system and associated plumbing, operation of a pretreatment system and maintenance of the effluent conveyance system to final treatment. KEMRON provided system optimization for both the recovery and pretreatment stages resulting in O & M cost savings. We installed additional recovery wells and provide repair services to the existing well network.

RCRA Facility Investigation. KEMRON implemented Stage III RFI activities at a chemical plant in Institute, West Virginia under a RCRA Corrective Action Permit issued by EPA Region III. The additional phase of RFI activities included preparation of site specific HASP, completion of 52 soil borings using Geoprobe direct push technology with depth specific groundwater samples collected at seven locations, sampling of 26 groundwater monitoring wells, eight geotechnical borings at a capped surface impoundment to document cap permeability conditions, and preparation of site-wide groundwater potentiometric surface maps. Based upon the findings of the initial phase of Stage III RFI activities, KEMRON completed additional investigations. Additional investigations consisted of 30 Geoprobe groundwater sample locations, six Geoprobe borings to evaluate landfill cap integrity, installation of one deep alluvium monitoring well, sampling of 20 monitoring wells and collection of surface water samples. KEMRON prepared a report summarizing the findings.

Soil Investigation. Under the West Virginia Voluntary Remediation and Redevelopment Program (VRRP), KEMRON conducted soil investigations on a vacant parcel of property where chemical manufacturing operations were conducted. KEMRON’s investigations consisted of the advancement of 13 shallow soil borings to eight (8) feet or less across the entire property. These investigations were conducted in order to evaluate potential environmental impacts and exposure issues in surface and near-surface soils prior to leasing the property to the City of South Charleston for construction of a new Welcome Center .

O & M: At this large, multi-tennant chemical manufacturing complex, KEMRON performed O&M activities and interfaced with the local operating plants. KEMRON personnel operated a leachate collection system; performed routine gas vent and groundwater monitoring activities; provided site security; ensured compliance of neighboring facilities with site S&H requirements; interfaced with regulatory agencies; provided response services for spills, and releases; and supervised subcontractors. Numerous special projects were completed by KEMRON in support of planned remedial activities. These projects included: preparation of a comprehensive site HASP; filtration, solidification and consolidation of wastewater and sludges contained in the 150 drums stored on site; inventorying, packaging and disposing of IDW and site chemicals; collection of over 400 discrete soil samples from the Rashing Area for furan analysis.

Groundwater Remediation: KEMRON installed and operated a large scale groundwater remediation system at this chemical plant. KEMRON installed recovery wells and piezometers and abandoned two existing recovery wells and one large production well. The hydraulic barrier wells were powered by pneumatic pumps, operated by a control system. Pneumatic pumping systems are utilized for groundwater recovery from other wells located at waste disposal units. Groundwater recovery in the highly productive river aquifer is accomplished by wells equipped with electric submersible pumps.

Remediation of Radioactive Slags: KEMRON completed a removal action of radioactive slags and metal. Work included preparation of a site sampling grid and collection of more than 80 soil samples for analysis. KEMRON provided assessment, containerization, testing and shipping of 90 specially designed containers of radioactive material. Activities also included over packing drums and containers of radioactive waste where the containers had deteriorated.

Landfill Closure: KEMRON implemented an excavation and on-site RCRA compliant landfill expansion/capping project. Excavations of dioxin contaminated soil were completed in active areas of the chemical manufacturing plant. The existing landfill was opened, and excavated soil was added to one end of the cell. New composite liner materials and gas/leachate collection systems were installed and tied into the existing system. KEMRON designed and conducted the excavation, transportation, and placement of the waste material and installation of the composite cap components including FML liner system.
