Recent advancement in enhanced soil flushing for …
Remediation of persistent organic pollutants in soil especially total petroleum hydrocarbon (TPH) is of global concern due to its toxicity and health implications. Soil flushing has been considered a promising technique among in-situ technologies for treating non-volatile TPH-contaminated soils because it weakens the interaction between hydrocarbons and soil …

Soil Washing
Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone …
