Light non-aqueous phase liquid - Wikipedia
WEBA light non-aqueous phase liquid (LNAPL) is a groundwater contaminant that is not soluble in water and has lower density than water, in contrast to a DNAPL which has higher density than water.
WEBSep 14, 2004 · DNAPL refers to Dense Non-Aqueous Phase Liquids (those that are denser than water). DNAPL (chlorinated compounds and PAHs) will not be dealt with in this training program.
