JESCO completed a RCRA Facility Investigation (RFI) and RCRA Corrective Measures Study for the USACE Fort Worth District on area Solid Waste Management Unit (SWMU) 26 at Fort Polk, Louisiana. Comprised of multiple areas spanning active vehicle maintenance units of the 2800, 2900, and 3000 Blocks of Fort Polk South, SWMU 26 housed a rail based vehicle and equipment fueling network built in the 1940s which included multiple fuel transfer, storage, and dispensing sites. Fuel was delivered via railroad or truck to three fill boxes and was subsequently pumped to an Above Ground Storage Tank (AST) farm comprised of six 12,000 gallon ASTs. Multiple four inch fuel lines distributed fuel 0.25 mile to refueling islands north and south of the tank farm. The Contaminants of Concern (COCs) are full suites of Volatile Organic Compounds, Semi-Volatile Organic Compounds (SVOCs), Diesel Range Organics (DRO), Gasoline Range Organics (GRO), and Metals
Prior to the soil and groundwater sampling, JESCO was responsible for physically locating the historic fuel system pipelines left in place after AST farm and fill box removal. Since no portion of the historic system was visible, our technical team investigated facility historic documents and state regulatory documents to determine approximate location of abandoned fuel system components. Once a historic facility map was developed, the JESCO field crew used heavy equipment, metal locators, line locators, and survey equipment to locate, evaluate, and map the abandoned lines.
JESCO conducted the RCRA Facility Investigation/LDEQ RECAP Site Investigation in 2012. Forty-five borings were advanced from ground surface to approximately 30 feet using continuous sampling procedures to sample soil and groundwater. In addition, six existing groundwater monitoring wells in the site vicinity were sampled and slug tested for additional groundwater data collection. Soil and groundwater contamination and geotechnical data were used to develop site specific standards, map contaminant plumes, and determine receptor exposure risks. JESCO utilized information obtained from the 2012 RFI to prepare a RCRA Corrective Measures Study (CMS) in 2014 for evaluation of remedial treatment technologies.
