Creosote and other non-aqueous phase liquids (NAPLs) are responsible for high pump-and-treat costs in groundwater remediation because, due to their molecular size, they tend to clog activated-carbon pores quickly. The result is frequent change outs, which renders the pump-and-treat method too expensive.
NAPLs are a class of hydrophobic-phase organic liquids that can form discrete layers in the aquifer. NAPLs are divided into two classes depending on their specific gravity.
