Nonaqueous Phase Liquids (NAPLs)

Top Previous Next

Definition

Organic compounds that do not dissolve readily in water.

Description

NAPLs do not readily dissolve in water, but either float or sink in it depending on its density. A NAPL contamination plume usually has multiphase flow.

Why are nonaqueous phase liquids important?

It is a common contaminant found in groundwater in urban and industrial areas.  It is difficult to detect and quantify the occurrence or movement thereof, therefore making remediation difficult.
