Dense Non-Aqueous Phase Liquids

Superfund Basic Research Program

Dense non-aqueous phase liquids (DNAPLs) are liquids that are heavier than water and have a low aqueous solubility. DNAPLs can cause kidney and liver damage and may affect the central nervous system causing headaches, dizziness, nausea and even unconsciousness. The remediation of DNAPL-contaminated sites has proven to be one of the most difficult problems facing the EPA Superfund program. SBRP-funded research has focused on novel clean-up approaches that would provide a more economical means of DNAPL remediation, thus resulting in reduced risk to humans and ecosystems.
