The document presents the results of a survey undertaken by the U.S. Environmental Protection Agency's (EPA's) Office of Emergency and Remedial Response (Superfund). The survey was designed to estimate the proportion of National Priorities List (NPL) sites where Dense Nonaqueous Phase Liquids (DNAPLs) may be present. Earlier studies by OERR suggested that DNAPLs may be more common at hazardous waste sites than previously thought, and may act as a continuing source of contamination thus reducing the ability of pump-and-treat systems to attain cleanup goals within expected timeframes (Evaluation of Ground Water Extraction Remedies, Phase II, EPA 9355.4-05). The study represents the first systematic nation-wide review of NPL sites designed to estimate the extent of subsurface DNAPL contamination.
