To keep our environmental industry clients and colleagues informed of recent and recognized developments in environmental remediation technologies and techniques, AST employs several methods of providing technology transfer that we feel are relevant, flexible, and important to our clientele. From live webinars to in-person presentations to on-demand training, our goal is to connect you with our experienced senior staff in a technical learning format that provides the proper assistance, collaboration, and efficient use of your time. Strongly, AST believes the information we present live or on-demand encompasses the best-available technology and techniques to remediate sites small and large, from heavily-impacted source areas to dilute plumes, phreatic to vadose zone, and comingled contamination to site civil activities.

BOS 200+® Site Granted NFA After 1 Year 

AST continues our platform presentation webinar series. In this 30 minute presentation Bill Brab, PG, CPG will provide an overview of a BOS 200+® project that was recently granted No Further Action (NFA) status. He will review the remedy design approach, in situ amendment application process and site-specific results. 

Trap & Treat® BOS 200+® was applied using direct push technology (DPT) methods at a former retail gasoline station site in Knoxville, Tennessee. Since installation of the BOS 200+®, there has been a 57-99% reduction in total BTEX, a 42-99% reduction in naphthalene, and an average increase of almost 200% in dissolved CO2 over the project monitoring period. The Tennessee Department of Environment and Conservation (TDEC) issued the NFA status for the project in 2022.
