Dense Non-Aqueous Phase Liquid DNAPL

Meaning, Term, and Glossary Definition - What is Dense Non-Aqueous Phase Liquid DNAPL?

Non-aqueous phase liquids such as chlorinated hydrocarbon solvents or petroleum fractions with a specific gravity greater than 1.0 that sink through the water column until they reach a confining layer. Because they are at the bottom of aquifers instead of floating on the water table, typical monitoring wells do not indicate their presence.
