Got NAPL? Advanced Imaging & Monitoring for Complex NAPL Sites
📅 Wednesday, August 26, 2026
⏰ 12:00–2:00 PM ET
💻 Free to attend
🎓 2 PDHs for EnviroClass Members
About the Webinar
Complex NAPL sites can be difficult to characterize using conventional sampling and monitoring wells alone. In this advanced technical webinar, John Fontana and Dr. Julio Zimbron will explore optical imaging and high-resolution site characterization (HRSC) tools that can reveal NAPL distribution, migration pathways, and changing subsurface conditions.
Through case studies and field applications, they will show how Optical Image Profiling, HPT-EC, and repeatable Clear-Well optical monitoring can improve conceptual site models, reduce uncertainty, and support more effective remediation decisions.
What You’ll Learn
✅ Optical imaging of complex NAPL distribution
✅ OIP & HPT-EC migration pathways
✅ HRSC data for better site models
✅ Limits of monitoring well data
✅ Groundwater & lithology effects on NAPL
✅ Repeatable optical NAPL monitoring
✅ Better remediation through HRSC
