Course Description

This course is designed for LSPs and environmental professionals seeking practical, cost-effective tools for NAPL site characterization. Participants will learn how each laser-induced fluorescence (LIF) system works, which LIF system to apply to which contaminant, what information LIF can provide, how to interpret that information, and attention to LIF’s limitations. Proper confirmation techniques and data interpretation using multiple lines of evidence will be discussed in detail.

“Source term” LNAPL and DNAPL substances are potent sources of dissolved phase contamination, making proper characterization of their subsurface architecture a keystone of remediation success. During this course, participants will learn how to apply and interpret LIF data to improve accuracy, reduce costs, and strengthen conceptual site models. LIF logs these NAPL continuously in the subsurface in real time, making it a highly cost-effective alternative to traditional soil sampling.

A Q&A session will follow the presentation.
