Understanding Indoor Vapor Intrusion Pathway

Continuing Education Credits 

The CT State Board of Examiners of Environmental Professionals (LEP Board) has approved this course for 8.0 hours of continuing education credits - CTLEP-362(rev). Note: If you have previously taken the 16 hr. version of this course (CTLEP-362), you cannot take this course and claim it for CT continuing education credits. The MA LSP Board has approved this course for 8 Technical credits (Course #1500a). Please note that LSPs who attended the 16 hour version of the course (Course #1500) that was offered in 2014 and 2015 cannot earn continuing education credits for attending this modified version. This course has also been approved in NY for 7.5 PDH(s) for Professional Engineering from The Practicing Institute of Engineering, Inc (PIE) - Course# 20160011.

Time and Location

This seminar will be held on Tuesday, May 24, 2016 and runs from 8 AM - 5 PM at the CTCPA Education Center, 716 Brook St., Ste. 100, Rocky Hill, CT. For directions, see: http://www.ctcpas.org/Content/About/Driving-Directions.aspx

Continental breakfast, lunch, and PM snack included.

Course Overview

This intermediate to advanced level comprehensive one-day applied course covers numerous aspects of the vapor intrusion pathway (VIP). Several state and federal programs have developed guidance documents and tools to evaluate this pathway. However, there exists significant variability in the available regulatory guidance and the evaluation of the VIP.

This training program presents an in-depth understanding of the underlying science of vapor migration in soil; methods to quantitatively and qualitatively evaluate the pathway; data needs and data collection techniques; vapor intrusion mitigation systems; regulatory requirements; and spatial and temporal variability in the factors that affect this pathway. Real world examples provide practical insights for additional clarity.

Course Highlights

  • Basic principles and transport mechanisms for solvents and hydrocarbons
  • The effect of climatic factors on vapor movement
  • Development of site conceptual model
  • Parameters that affect vapor inhalation risk
  • Development of work plans and data collection
  • Relevant federal and state regulations
  • Johnson and Ettinger and other available models
  • Vapor mitigation techniques and systems, and
  • Site specific examples.

Who Should Attend

The course will benefit professionals from industry, consulting, and regulatory agencies who are required to evaluate this pathway; perform or are responsible for site investigations; manage or conduct health risk assessments at contaminated sites; establish and negotiate environmental cleanup levels; design and implement remedial action plans; and provide litigation support.

Learning Objectives and Benefits

After attending this course, you will be able to:

  • Appreciate the technical and regulatory challenges in evaluating the pathway
  • Current industry and regulatory trends
  • Understand the scientific basis and assumptions inherent in various fate and transport models
  • Quantitatively and qualitatively understand vapor intrusion risk assessment
  • Understand the differences in various guidance documents and regulations
  • Understand the data needs and data collection methods to evaluate this pathway
  • Develop strategies to cost-effectively address this pathway and add value to your projects
  • Confidently explain, negotiate, and evaluate various aspects of this pathway

Hands-on calculations and case studies will improve the understanding of the concepts discussed. Site specific examples will help demonstrate the practical use of vapor intrusion evaluation, regulatory negotiations, and establishing clean-up goals.

Participants are requested to bring calculators.

Instructor Bio

Dr. Atul M. Salhotra is an internationally recognized expert in the cost-effective management of contaminated sites. His expertise and opinions are sought after and trusted by regulators, industries, and the courts by virtue of his having developed risk based decision making programs for the management of chemically impacted sites for more than 15 states. He is the lead author, project manager, and developer of Risk-Based Corrective Action (RBCA) programs for numerous states, and the U.S. Air Force in Europe (USAFE). As one of the original nine ASTM certified trainers for RBCA, he has conducted training courses in over 25 states and 10 countries. Over 6,000 individuals have attended his courses and benefited from the training received.

Dr. Salhotra is well versed in the site-specific application of risk assessment, evaluation of indoor vapor intrusion, natural attenuation, and fate and transport modeling for the cost- effective management of sites. He has supervised over 200 risk assessments under state and federal programs involving hydrocarbons, solvents and metals, and has successfully defended the results with regulatory agencies and other stakeholders across the country.

Dr. Salhotra has provided litigation support, including testimony in courts, on numerous high-profile projects related to the migration of plumes under people’s homes, the allegation of adverse health effects due to vapor intrusion, and diminution of property values. Several of these projects involved public meetings, risk communication presentations, and media coverage.
