ESTCP Project ER-201584, 632 pp, 2017

The five sites selected for the ER-201584 demonstration project were Hill AFB OU-10, Hopewell Precision Site, Tooele Army Depot, the former Twin Cites Army Ammunition Plant, and the former Plattsburgh AFB. The objectives were to (1) provide a method to readily and inexpensively acquire the magnetic susceptibility data required to evaluate the abiotic degradation of TCE by magnetite in aquifer materials using existing non-metallic groundwater monitoring wells, and (2) provide a method to readily and inexpensively acquire the data required to evaluate and quantify the rate constant for aerobic biological co-oxidation of TCE. This report shows that an inexpensive downhole sonde (probe) can be used in existing 2- and 4-inch PVC groundwater monitoring wells to quantify magnetic susceptibility of aquifer material. The cost to determine volume magnetic susceptibility in one well using a down-hole sonde was ~$2,000. Additional per-well costs were ~$476 for C-14 assay of the rate constant of TCE cooxidation; ~$1,900 for EAP assay; and ~$835 for qPCR analyses. https://www.serdp-estcp.org/content/download/46230/430569/file/ER-201584%20Final%20Report.pdf See also the ESTCP Cost and Performance Report at https://www.serdp-estcp.org/content/download/46339/431460/file/ER-201584%20Cost%20&%20Performance%20Report.pdf.
