On-Site Analysis for High Concentrations of Explosives in Soil Extraction Kinetics and Dilution Procedures.
Abstract
The main objective of our study was to determine the rate of extraction of secondary explosives from highly contaminated soil to ensure that on-site methods currently available can provide sufficiently accurate results for soils contaminated with percent levels of TNT and RDX. Field-contaminated soils from a number of installations were utilized in these assessments. Because the most commonly used on-site methods for explosives in soil specify either acetone or methanol as the extraction solvent, much of the work evaluated extraction using these solvents. Based on these results, recommendations will be made on modifications to established protocols for available on- site methods for determining whether concentrations exceed the 10% safety criterion. Since large dilution factors (about 1 to 10,000) are required to reduce extract concentrations to the range suitable for these tests, a dilution procedure that is simple and sufficiently accurate and precise will be provided.
