Light non-aqueous phase liquid
A Light Non-Aqueous Phase Liquid (LNAPL) is a groundwater contaminant that is not soluble and has a lower density than water, which is the opposite of DNAPL. Once LNAPL infiltrates through the soil, it will stop at the height of the water table since LNAPL is less dense than water. The effort to locate and remove LNAPL is relatively cheaper and easier than DNAPL because LNAPL will float on top of the water in the underground water table.
