Light, non-aqueous 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. The result can be long-term risk and exposure issues, such as vapor intrusion and groundwater, surface water and soil contamination. LNAPLs may present acute-risk concerns, such as explosive conditions, aesthetic concerns, or in some cases, pose no risk. Regulatory drivers for LNAPL 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 contamination sites. The ITRC guidance document 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 enabled participants 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 reinforced these course learning objectives. Participants also had the opportunity to network with other environmental professionals.
