Bryan VanDuinen to Present on Vapor Intrusion Mitigation Design at Midwestern States Environmental Consultants Association Spring Seminar

Bryan VanDuinen, P.E. (Michigan) will present at the Midwestern States Environmental Consultants Association's (MSECA) Spring Seminar at the Regions Tower in Indianapolis, Indiana on May 3, 2018.

His presentation is entitled "High Volume Sampling: An Innovative Tool for Vapor Intrusion Mitigation Design (a Case Study)."

Bryan is a professional environmental engineer with experience in: assessing, remediating, and closing sites impacted by petroleum hydrocarbons, chlorinated solvents, and metals; geographical information systems (GIS); data management, visualization, and analysis; and mathematical modeling.

This year's MSECA Spring Seminar on Vapor Intrusion will focus on three areas:

  • Updated investigation and remediation methods with real world case studies
  • Preferential pathway vapor migration through sewers
  • Regulatory updates

The seminar will also include the most updated EPA research around indicators, tracers, and surrogates (ITS), which include a collection of quantifiable metrics and tools that may have the potential for making vapor intrusion pathway assessment and long-term monitoring more informative, efficient, and cost-effective.

MSECA advances the field of environmental consulting by improving the professional competence of its members through education and dissemination of information related to technical developments, regulations, training, and codes, all pertaining to environmental protection. Collectively, they represent hundreds of professional consultants, along with vendors and suppliers to the environmental consulting community.

Presentation Description

During the evaluation of VI risks at a large, active manufacturing facility impacted by trichloroethene (TCE), the Michigan Department of Environmental Quality began revising its cleanup criteria rules. The draft cleanup criteria were developed using a lower nonresidential indoor air screening level (IASL) for TCE. Based on potential risk, a vapor mitigation system was selected to reduce indoor air concentrations below the draft IASL. High volume sampling (HVS) provided a quick and cost-effective way to characterize sub-slab impacts across a large area and obtain data for mitigation system design.
