High Resolution Site Characterization tools-DyeLIF


The Dye-enhanced laser induced fluorescence system (DyeLIF) tool is a new site characterization technology that facilitates rapid, cost-effective 3-dimensional (3-D) delineation of residual chlorinated solvent DNAPL in the subsurface. DyeLIF is based on combining time-resolved LIF technology with the injection of a fluorescent dye ahead of the window to render non-fluorescent NAPLs fluorescent in-situ. This new technology has potential to rapidly delineate DNAPL source zones at sites where direct push is feasible, significantly improving prospects for targeted remediation. See links in Resources panel on this page for details regarding an ESTCP-funded technology demonstration conducted at a Formerly Used Defense (FUD) facility in Massachusetts in Fall 2013 (Geoprobe® delivery) and again in March 2014 (CPT delivery).
