The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you:

  • Build upon your Understanding of LNAPL Behavior in the Subsurface (Part 1)
  • Develop your LNAPL Conceptual Site Model and LNAPL Remedial Goals (Part 2)
  • Select/Implement LNAPL Technologies (Part 3)
The Biofuels training course addresses the causes and prevention of post-manufacture biofuel releases, impacts to environmental media, characterization methods, remedial responses, and stakeholder concerns.

The training course helps dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. These differences are the focus of this training.

The Mass Flux training course summarizes the concepts underlying mass flux and discharge, their potential applications, and case studies of the uses of these metrics.
Petroleum Vapor Intrusion (PVI) is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light non-aqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. This training course provides a comprehensive methodology for screening, investigating, and managing potential PVI sites.

This training course provides a holistic process for management of challenging sites, termed “adaptive site management.” This process is a comprehensive, flexible, and iterative process that is well-suited for sites where there is significant uncertainty in remedy performance predictions.
