When DNAPL from coal tar, creosote, or chlorinated solvents resists removal, In Situ Geochemical Stabilization (ISGS) coats the NAPL blobs with thick mineral crusts — reducing contaminant flux while the ISGS Reagent simultaneously destroys dissolved-phase PAHs in the groundwater. IET's exclusively licensed, field-proven approach to source-zone stabilization.

Chlorinated solvents like TCE and PCE remain among the most persistent groundwater contaminants in the U.S. — but with the right chemistry, rapid and lasting destruction is achievable. Here's why IET's ferric iron-activated persulfate ISCO approach works.

Contaminated site with a stubborn DNAPL source zone? Excavation isn't always the answer — and with IET's patented EZVI technology, it doesn't have to be. 99%+ reductions in source zone concentrations without dig-and-haul.

When environmental consultants are selecting an in-situ remediation contractor, the stakes are high — site closure timelines, client budgets, and regulatory outcomes all depend on execution. Here's why so many consultants come back to IET, project after project.

From environmental site characterization to geotechnical investigation, the right drilling method makes all the difference. IET's multi-platform fleet — Direct Push, Hollow-Stem Auger, Mud Rotary, Air Rotary, and Rock Coring — matches the right tool to both environmental and geotechnical objectives.

Enhanced bioremediation is one of the most effective — and environmentally responsible — strategies for treating chlorinated solvents and petroleum hydrocarbons in groundwater. A self-sustaining remediation system that keeps working even when we're not on-site.
