In this webinar we are pleased to a special presentation from Jessica Law, engineering geologist and case manager for the Santa Ana Regional Water Quality Control Board. This presentation discussed a case study outlining the largest residential vapor intrusion investigation in California at the site of a former aerospace manufacturer. Ms. Law provides a thorough overview of the team’s effort to manage both community concerns and changing regulatory guidelines as it applies to this challenging investigation. Joining Ms. Law was Thomas Szocinski, CEP Land Science Director of Vapor Intrusion, who shared effective approaches to mitigating vapor intrusion on sites like the one discussed in the featured case study. 

Key Topics Addressed in This Webinar Include:

  • Practical and effective approaches to managing community concerns and interest
  • Key principles as covered in the Supplemental Vapor Intrusion Guidance currently out for public comment
  • Data collected and currently being utilized in two of the three attenuation factor studies currently ongoing
