IPEC 2020: Design Rational for Selecting Vacuum Blower Flow Rate and Inlet Vacuum for Active Sub-Slab Vapor Intrusion Mitigation Systems

Primary Author / Conference Presenter: Robert Roth Sr. Engineer Terracon Wheat Ridge, CO, USA www.terracon.com Co-Author: Joe Yang, Terracon, Tustin, California Sub-slab vapor intrusion mitigation system (VIMS) pilot tests were conducted at eight sites in six states with 44 sets of data that were used to estimate the sub-slab radius of vacuum influence (ROI) as…

Advances in Oil Spill Forensic using Biomarkers and Isotope Ratio Technique.

Determination of parties liable or guilty in order to recover costs of the cleanup and remediation, has grown dramatically in last decade, environmental forensics has emerged as a discipline directed toward this goal. Traditionally, these studies have been addressed through utilization of techniques such as gas chromatography (GC) and gas chromatography–mass spectrometry (GCMS). Biomarkers play…
