Dense non-aqueous phase liquid (DNAPL)

Dense non-aqueous phase liquid (DNAPL)

Definition

DNAPLs are denser-than-water liquids, such as CHCs, that may exist in the ground as discrete or interconnected droplets or shallow pools on low-permeability layers. These substances are not very soluble in groundwater, so may exist for a long time, slowly dissolving and contaminating passing groundwater.
