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 anew optical screening tool, that extends the LIF technology to chlorinated solvent DNAPLs.
