Comprehensive Remediation Solutions
IET provides full-spectrum environmental remediation — from industrial brownfields to groundwater treatment, combined technology programs, and remedial design characterization.
Industrial Site Cleanup
IET specializes in remediation of complex industrial properties including manufacturing facilities, former gas stations, dry cleaners, chemical plants, and MGP sites. Our turn-key approach integrates site characterization, remedial design, technology selection, and full-scale implementation — managing the entire cleanup under one contract.
Brownfield Site Assessment & Cleanup
IET supports brownfield redevelopment by delivering cost-effective in-situ remediation that achieves regulatory closure and enables safe property reuse. Our engineers work alongside developers and environmental consultants to design targeted treatment programs that meet cleanup goals on schedule — from Phase II ESA through regulatory closure.
Groundwater Treatment Services
IET treats contaminated groundwater in situ — eliminating the need for pump-and-treat systems and their perpetual operating costs. In-situ approaches using ISCO, enhanced bioremediation, and ISCR destroy dissolved contaminants directly in the aquifer, reducing plume extent and achieving MCL-level cleanup goals in the saturated zone.
Soil Vapor Extraction & Air Sparge Systems
IET designs and supports the installation of soil vapor extraction (SVE) systems and air sparge (AS) systems for volatile organic compound (VOC) removal from the vadose zone and groundwater. SVE/AS can be combined with bioremediation enhancements or ISCO for a synergistic treatment approach on petroleum and chlorinated solvent sites.
Combined & Sequential Remediation Technologies
Maximizing cleanup efficiency often requires combining multiple technologies. IET designs integrated programs — e.g., ISCO source zone destruction followed by enhanced bioremediation plume polishing — leveraging synergies between chemical, biological, and physical processes. One team, one mobilization, multi-mechanism treatment.
Remedial Design Characterization
Effective remediation begins with detailed site characterization. IET conducts remedial design investigations including bedrock and overburden characterization, contaminant source delineation, DNAPL investigation, and hydrogeologic analysis to build treatment programs supported by site-specific data — not assumptions. We combine drilling, sampling, and advanced site assessment tools.
Need Site Investigation & Drilling?
IET operates 50+ specialized rigs — Geoprobe, CME, AMS & barge drilling for site characterization, monitoring wells, and amendment injection.
