Chlorinated solvents are among the most common organic contaminants detected in groundwater at Department of Defense DoD sites. The sources of these contaminants are often historical releases of dense non-aqueous phase liquids DNAPL. Unfortunately, chlorinated solvent DNAPL source zones are difficult to locate using conventional subsurface characterization technologies. Laser-induced fluorescence LIF tools are currently available for real-time, high-resolution mapping of petroleum hydrocarbon and coal tar-based NAPL source zones. The objective of this project is to demonstrate a new optical screening tool, that extends the LIF technology to chlorinated solvent DNAPLs.
