Introduction to Light Non-Aqueous Phase Liquids (LNAPL)
In Introduction to Light Non-Aqueous Phase Liquids (LNAPL), you'll learn ...
- The chemical make-up of a Light Non-Aqueous Phase Liquid (LNAPL)
- Parameters that influence LNAPL transport
- The fate of LNAPLs in the subsurface
- LNAPL site characterization
Overview
LNAPLs are hydrocarbons that exist as a separate, immiscible phase when in contact with water, and by definition have densities less than that of water. LNAPLs affect groundwater quality at numerous sites across the country, where they must be addressed when performing site remediation.
In general, LNAPLs represent potential long term sources for continued groundwater contamination. The transport, fate, characterization, and remediation of light non-aqueous phase liquids (LNAPLs) in the environment are issues of concern. 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 is applicable to engineers involved with the design, construction, operation, and monitoring phases of site remediation where LNAPLs are present.
