This webinar is a result of Recommendation 9 of EPA's Superfund Task Force, which encourages the Superfund program to "utilize state-of-the-art technologies to expedite cleanup." Actions under this recommendation include expanding the use of new remediation technologies and approaches to address contaminated sites.

In this webinar, we will present an overview of in situ activated carbon (AC)-based remediation technology, discuss important considerations for site characterization and treatment design, and present characterizations of physical, chemical and biological processes involved in a long-term case study where reactive AC-based technology was applied.
