TREATMENT OPTIONS FOR THE EMERGING CONTAMINANTS 1,2,3-TRICHLOROPROPANE AND 1,2-DIBROMOETHANE
Hatzinger, P., and P. K. van Groos.
SERDP/ESTCP Webinar Series, Webinar #90, May 2019
The webinar consisted of two presentations. The first summarized ESTCP-funded research to demonstrate a novel reactive gas process for remediating vadose zone source areas containing trichloropropane (TCP). Lab treatability studies suggest that the process can be a viable approach for increasing soil pH and enhancing the alkaline hydrolysis of TCP and other COCs in a cost-effective manner. In the second presentation, 1,2-dibromoethane (EDB) natural attenuation was evaluated at a complex field site. In higher-concentration anaerobic zones at the site, the presence of ethene suggested that anaerobic debromination of EDB occurred, while in more dilute areas, EDB enriched in 13C indicated slower degradation consistent with abiotic hydrolysis. In lab studies, anaerobic biostimulation was demonstrated to enhance EDB degradation in the field together with the enrichment of 13C in EDB. https://www.serdp-estcp.org/Tools-and-Training/Webinar-Series/05-23-2019
