The U.S. EPA has compiled a summary of information on the current state of technologies available for locating and characterizing dense non-aqueous phase liquid (DNAPL) contaminated sites. This summary is intended to help managers at sites with potential or confirmed DNAPL contamination identify suitable characterization technologies, screen the technologies for potential application, learn about applications at similar sites, and locate additional information on these technologies. Due to its unique manner of migrating and pooling within soil pores and rock fractures, DNAPL in free-phase or residual form is difficult to find and measure. DNAPLs typically contain chlorinated hydrocarbon compounds or industry-specific contaminants resulting from activities such as wood-treating, pesticide/herbicide manufacturing, or coking operations. Relatively small quantities of DNAPL that sink into soil and accumulate below the water table constitute a long-term source of groundwater contamination.
