Direct Push Optical Screening Tool for High Resolution, Real-Time Mapping of Chlorinated Solvent DNAPL Architecture

Abstract

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.
