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.
Non-Aqueous Phase Liquid (NAPL): Contaminants that remain undiluted as the original bulk liquid in the subsurface, e.g., spilled oil. (see Fee Product

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.
Dense Non-Aqueous Phase Liquid (DNAPL)
A liquid that does not dissolve in water, and so forms a separate phase from water, which is also denser than water and therefore sinks. Many chlorinated solvents are DNAPLs.

Non-aqueous phase liquids 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.

Dense Non-Aqueous Phase Liquid (DNAPL): A non-aqueous phase liquid (NAPL) with a specific gravity greater than 1.0. Because the specific gravity of water is equal to 1.0, DNAPLs sink through the water column until they encounter a confining layer.
free product A petroleum hydrocarbon in the liquid ("free" or non-aqueous) phase (see also non-aqueous phase liquid, NAPL).
