Webinar was held on May 8, hosted by GHD.
Recent years have brought a new understanding of the potential magnitude and importance of natural LNAPL biodegradation (referred to as Natural Source Zone Depletion or NSZD) in the remediation and management of petroleum-contaminated sites as evidenced by contemporary guidance from the American Petroleum Institute (API) and the Interstate Technology & Regulatory Council (ITRC) in the U.S., and CRC-CARE in Australia. It is now understood that most of the petroleum degradation happening at LNAPL sites will be manifested through observable changes in LNAPL composition over time, soil gas content and/or vadose zone temperature profiles.
