Light Nonaqueous-Phase Liquids: Science, Management, and Technology
Hosted by Interstate Technology and Regulatory Council (ITRC)

Light, nonaqueous-phase liquid (LNAPL) assessment and remediation presents a significant challenge for corrective action and cleanup at petroleum processing, storage, and handling facilities such as refineries, bulk product terminals, gas stations, airports and military bases. Once in the subsurface, LNAPLs can be difficult to adequately assess and remediate. The result can be long-term risk and exposure issues such as vapor intrusion, groundwater, surface water and soil contamination or other risk sensitive habitat. It may present acute-risk concerns such as explosive conditions or LNAPL may pose aesthetic concerns, or in some cases, pose no risk. In addition, regulatory drivers for LNAPL concerns present challenges to site closure, such as regulations that require recovery of "free product," (a.k.a., "free-phase hydrocarbon" and "liquid-phase hydrocarbon") to the agency determined "maximum extent practicable." ITRC offers this 2-day classroom training course, based on ITRC's Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2) to assist environmental practitioners with applying science-based solutions for LNAPL sites. The ITRC guidance was developed through the combined efforts of environmental professionals, including state and federal regulators, consultants, industry, and community stakeholders.

This 2-day ITRC classroom training led by internationally recognized experts should enable you to:
- Develop and apply an LNAPL Conceptual Site Model (LCSM)
- Understand and assess LNAPL subsurface behavior
- Develop and justify LNAPL remedial objectives including maximum extent practicable considerations
- Select appropriate LNAPL remedial technologies and measure progress
- Use ITRC’s science-based LNAPL guidance to efficiently move sites to closure

Interactive learning with classroom exercises and Q&A sessions will reinforce these course learning objectives. You will also have the opportunity to network with other environmental professionals.
