Eric Suchomel, Ph.D., P.E., is a senior environmental engineer for Geosyntec based in California. Dr. Suchomel's professional practice at Geosyntec includes site investigation and characterization; design and implementation of soil, groundwater, and soil vapor remediation systems; litigation technical support; and remediation technology research and development. He specializes in the development and demonstration of innovative technologies for the remediation of TCP, and he worked with the U.S. Navy to implement the first field demonstration of zero valent zinc to treat this emerging contaminant. .


Field Validation of Low-Level TCP Remediation Approaches

1,2,3-Trichloropropane (TCP) is an emerging groundwater contaminant characterized by high mobility in the subsurface, resistance to natural attenuation and some engineered remedies, and low regulatory levels relative to other volatile organic compounds. Since the mid-2000s, Geosyntec and collaborators have been evaluating remedial technologies TCP, including groundwater extraction and treatment, in situ chemical oxidation (ISCO), in situ chemical reduction (ISCR), and in situ bioremediation (ISB). Of these, ISB and ISCR have been identified as particularly promising technologies for TCP remediation at the low concentrations of regulatory interest, and proof-of-concept testing has been implemented in the past several years at scales ranging from laboratory treatability studies to full-scale field implementation. This presentation includes results from ongoing research and field studies intended to validate ISB and ISCR as technologies for remediation of low levels of TCP in groundwater.
