Nonaqueous phase liquid (NAPL) A water-immiscible liquid that can cause ground water contamination. This term is unique to ground water contaminant hydrology. The common examples are fuels, chlorinated solvents, creosote and coal tar. A NAPL may be less dense than water--a Light Nonaqueous Phase Liquid (LNAPL), or it may be denser than water--a Dense Nonaqueous Phase Liquid (DNAPL).
