Well Injection Depth Extraction (WIDE) Soil Flushing. Industry Programs.

DE2001781472

Publication Date	2001
Page Count	30
Abstract	Contamination in low-permeability, high-clay-fraction soils poses a significant technical challenge to in situ remediation efforts. Conventional technologies such as pump and treat groundwater remediation, and vapor extraction using conventional well fields, are typically ineffective when applied to sites with low permeability soils. This report describes an innovative subsurface remediation technology, termed Well Injection Depth Extraction (WIDE), has been developed by researchers from North Carolina State University (NCSU). The WIDE system is a hybrid soil flushing/soil gas extraction system that uses Prefabricated Vertical Wells (PVWs) for the in situ remediation of contaminated fine-grained soils.
