About the Course

You'll build a critical foundation for understanding estimation of LNAPL Transmissivity (Tn). These concepts will teach you about the practical limits for hydraulic recovery of subsurface petroleum and create effective remedial strategies. You will learn how multiple occurrences of LNAPL (confined, perched, unconfined) affect LNAPL Tn, as well as discern which calculation methods are appropriate for each condition. Topics will include analyzing skimming test data, baildown test data, and previously collected remediation system data.

Learn About

Upon completion of this training, attendees should be able to:

  • Identify an appropriate method(s) for calculating LNAPL Transmissivity
  • Use these methods to collect data and process the data through a proper set of equations
  • Recognize poor data points and remove them from LNAPL Transmissivity calculations
  • Select the appropriate methodology based on site conditions
  • Use the results of the analyses for making better remedial decisions about remediation approaches
Who Should Attend

This course is designed for LSPs, environmental consultants, and others in the LSP community. Attendees should have a basic understanding of hydrogeologic processes and non-aqueous phase liquid (NAPL) fundamentals. It is recommended that all attendees become familiar with the E2856 Standard in order to maximize the use of their time at the workshop.

About ASTM and Sponsoring Committee

ASTM is one of the world's largest voluntary standards development organizations. Recognizing the need for authoritative site assessment standards, ASTM pulled together environmental professionals, real estate and insurance professionals, lawyers, and government representatives. These members of Committee E50 and its Subcommittee E50.02 on Commercial Real Estate Transactions developed the standards upon which this course is based. For more information on Committee E50 contact Molly Lynak or go to our E50 technical committee page.

ASTM publishes the 82-volume Annual Book of ASTM Standards (available on CD ROM), which contain over 12,000 standards written by 34,000 members on 140 technical committees. These standards are widely used throughout the world as the basis of purchasing and other contracts, codes, laws and regulations.
Attention: Professional Engineers

If your state has a continuing education requirement for license renewal, ASTM training courses and ASTM membership can help you meet that requirement. This course provides 1.4 CEUs. A Certificate of Completion is provided at the end of the course listing CEU credit.
