Introduction to Light Non-Aqueous Phase Liquids (LNAPL)
This online engineering PDH course presents LNAPL physical and chemical properties, transport and fate, and methods for site characterization and remediation.
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 3 PDH online course is applicable to engineers involved with the design, construction, operation, and monitoring phases of site remediation where LNAPLs are present.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding of LNAPL physical and chemical properties
- Understanding of LNAPL transport through porous media
- Understanding of the fate of LNAPLs in the subsurface
- Considerations and methods for LNAPL site characterization
- Considerations and methods for LNAPL remediation
In this professional engineering CEU course, you will need to review the EPA publication "Ground Water Issue - Light Nonaqueous Phase Liquids", EPA 540-S-95-500.
