WebA light, non-aqueous phase liquid (LNAPL) is a liquid such as gasoline, diesel, or other petroleum-based fuel, waste oil, and crude oil that is immiscible with water and that has a density less than that of water (<1 g/cm 3 ). Spills or releases of LNAPLs to the environment are common at petroleum manufacturing, storage, and handling facilities ... WebFree product recovery technologies apply to the recovery of an LNAPL source in the capillary fringe and saturated zones.

WebA light non-aqueous phase liquid (LNAPL) is a groundwater contaminant that is not soluble in water and has lower density than water, in contrast to a DNAPL which has higher density than water. Once a LNAPL infiltrates the ground, it will stop at the height of the water table because the LNAPL is less dense than water. Efforts to locate and remove … WebThe change in the LNAPL plume footprint (i.e., smear zone) is shown at time intervals 1½ years apart (gray versus bluish yellow areas). Key findings are that LNAPL migration did not follow the groundwater gradient, but rather had a radial LNAPL gradient caused by the release. Additionally, a portion of the plume apparently migrated upgradient WebMay 3, 2024 · In geothermal energy applications, we use FEFLOW most for low-temperature projects, such as thermal groundwater installations or in combination with geothermal heat exchangers and energy piles.
