Environmental Remediation Case Studies
Featured Project: Chlorinated Solvent & Chromium Remediation
Cleveland Development Project
The remediation site is located in Cleveland, Ohio. The site contained soil and groundwater impacted by trichloroethene (TCE), cis-1,2-dichloroethene, vinyl chloride, and hexavalent chromium. IET's in-situ injection program targeted these compounds through compressed nitrogen and a solution of EHC-M, calcium propionate, and an oxygen scavenger.

Key Takeaways
- In situ remediation treats contaminated soil and groundwater in place without excavation, using patented technologies including ISCO, ISCR, enhanced bioremediation, EZVI, and ISGS.
- IET has completed over 3,500 projects nationwide since 1998, serving all 50 US states, Puerto Rico, and Canada from six regional offices.
- 14 patented technologies provide turn-key design and implementation for chlorinated solvents, petroleum hydrocarbons, metals, NAPL, and MGP waste.
- 50+ specialized drilling rigs support environmental, geotechnical, direct push, and barge-mounted marine drilling operations.
- Free AI-powered tools are available for site assessment, project analysis, and environmental data evaluation — no login required and files are never saved.
Key Terms & Definitions
- ISCO (In Situ Chemical Oxidation)
- A remediation technology that injects oxidants — such as activated persulfate, permanganate, or hydrogen peroxide — directly into contaminated soil and groundwater to chemically destroy organic pollutants in place.
- ISCR (In Situ Chemical Reduction)
- A remediation approach that uses reducing agents, primarily zero valent iron (ZVI), to chemically reduce contaminants such as chlorinated solvents and hexavalent chromium into non-toxic forms.
- Enhanced Bioremediation
- A biological treatment method that injects organic substrates and sometimes specialized microbes into the subsurface to stimulate the natural degradation of contaminants like chlorinated solvents and petroleum hydrocarbons.
- EZVI (Emulsified Zero Valent Iron)
- A patented nanoparticle technology that destroys chlorinated solvent DNAPL in situ through abiotic reductive dechlorination, combining food-grade surfactant, vegetable oil, and zero valent iron.
- ISGS (In Situ Geochemical Stabilization)
- A patented technology that stabilizes NAPL, coal tar, and creosote in place using permanganate-based oxidative polymerization, preventing contaminant migration without extraction.
- DNAPL (Dense Non-Aqueous Phase Liquid)
- A liquid contaminant that is denser than water and sinks through the groundwater column, creating persistent source zones — typical of chlorinated solvents like TCE and PCE.
- Direct Push Drilling
- A drilling method that pushes hollow steel rods into the ground using hydraulic percussion, enabling rapid soil sampling, groundwater screening, and injection point installation without generating drill cuttings.
