Dense nonaqueous phase liquids (DNAPLs), such as some chlorinated solvents, coal tar wastes, creosote based wood-treating oils, and some pesticides, are immiscible fluids with a density greater than water. As a result of widespread production, transportation, use, and disposal of hazardous DNAPLs, particularly since 1940, there are numerous DNAPL contamination sites in North America. The potential for significant long-term groundwater contamination by DNAPL chemicals at many sites is high due to their toxicity, limited solubility (but much higher than drinking water limits), and significant migration potential in soil gas, groundwater, and/or as a separate phase liquid, DNAPL chemicals, particularly chlorinated solvents, are among the most prevalent groundwater contaminants identified in groundwater supplies and at waste disposal sites.
