Improper disposal, accidental spills and leaks of non-aqueousphase liquids (NAPL) such as gasoline, fuel oil and creosote result in long-term persistent sources of groundwater …
Leaking from underground storage and surface spills of hydrocarbon sources can cause serious nonaqueous phase liquid (NAPL) contamination in subsurface environments. The …
The ability of food grade aqueous surfactant solutions to remove toluene or 1, 2, 4- trichlorobenzene entrapped in sand and two Iowa soils was evaluated in batch and column …
