The U.S. Environmental Protection Agency (USEPA) is committed to the identification and resolution of groundwater issues affecting the remediation of contaminated sites. The USEPA has identified the transport, fate, characterization, and remediation of light non-aqueous phase liquids (LNAPLs) in the environment as an issue of concern.
Light non-aqueous phase liquids (LNAPLs) are hydrocarbons that exist as a separate, immiscible phase when in contact with water, that affect groundwater quality at numerous sites across the country. In general, LNAPLs represent potential long term sources for continued groundwater contamination. LNAPLs have the ability to transport through porous media depending on parameters such as density, viscosity, interfacial tension, capillary pressure, saturation and residual saturation, and relative permeability. Challenges include the prediction of LNAPL transport, distribution, and migration; the fate of LNAPL in the subsurface; LNAPL site characterization; and LNAPL recovery and/or remediation.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
