Soil Flushing Description

Overview
General injection or infiltration of a solution into a zone of contaminated soil/groundwater, followed by down gradient extraction of groundwater and elutriate(flushing solution mixed with the contaminants)and above ground treatment and/orre-injection. This remediation technology will focus on the use of surfactants with U.S. Food and Drug Administration (FDA) direct food additive status.Surfactants offer the potential for increasing the solubility of environmental contaminants in water, making them more available to microorganisms involved in biodegradation. This method depends upon local site hydrogeology, site microbiology. And chemistry. Therefore, multiple combination technologies were used at many sites.

Characteristics
- Excellent efficiency for NAPLs(Non-Aqueous Phase Liquids)
- On-site Remediation Technology
- Economic and Safety
- Convenient in Metropolitan Area
