The Deep Remediation Injection System (DEW is a method utilizing the in-situ placement of remedial agents and air for on-site subsurface cleanup operations. It injects agents such as oxidizing chemicals, microbes, and nutrients into contaminated soils and groundwater to depths of 30 feet. High-pressure, low-volume injection is done with portable equipment. Air simultaneously injected through a lance into the impacted media increases the effectiveness of the remediation method.
