What is in-situ chemical oxidation (ISCO)?

In-situ chemical oxidation (ISCO) is an environmental remediation technique where chemical oxidants such as persulfate, permanganate, or hydrogen peroxide are injected into contaminated soil and groundwater to destroy organic contaminants like TCE, PCE, and petroleum hydrocarbons in place — without excavation.

What contaminants can IET remediate?

IET specializes in TCE remediation, chlorinated remediation, and comprehensive environmental treatment. We remediate chlorinated solvents (TCE/trichloroethylene, PCE/perchloroethylene, DCE, vinyl chloride), petroleum hydrocarbons (BTEX, gasoline, diesel, MTBE), heavy metals (chromium, lead), NAPL, DNAPL, PAHs, creosote, and mixed contamination using ISCO, ISCR, bioremediation, EZVI, and ISGS technologies.

How long does environmental remediation take?

Remediation timelines vary by technology and site conditions. ISCO can achieve significant contaminant reduction in weeks to months. Enhanced bioremediation typically requires 2–5 years of active treatment. IET's patented ferric iron-activated persulfate provides sustained treatment lasting over 2 years to prevent contaminant rebound.

What states does IET provide environmental drilling services?

IET provides environmental and geotechnical drilling services nationwide including Pennsylvania, Ohio, North Carolina, South Carolina, Texas, Florida, New Jersey, New York, Virginia, Georgia, Tennessee, Indiana, Illinois, and more. IET operates 50+ specialized rigs including CME, Geoprobe, AMS, and barge drilling equipment.

Multi-Area Injection Program

Large-Scale Multi-Phase Remediation

Grand Rapids, MichiganJuly-September 2020

Project Overview

IET executed a massive multi-phase injection program for AECOM in Grand Rapids, MI, completing treatment across ten distinct areas (SF, AB, HI, GH, FG, EF, BC, CD, DE, BG) with 315 total injection points. This multi-month project demonstrates IET's capability to manage complex, phased remediation programs with extensive site coverage and precise injection protocols.

Treatment Phases

Phase 1 (July 8-31, 2020)

Areas SF (24 pts), AB (48 pts), HI (54 pts), GH (5 pts), FG (24 pts) = 155 injection points

Phase 2 (August 4-14, 2020)

Areas EF (62 pts), FG additional (51 pts), GH additional (59 pts), DE (14 pts), BG (3 pts) = 189 points

Phase 3 (September 1-17, 2020)

Areas BC (31 pts), CD (40 pts), DE additional (45 pts), EF additional (10 pts) = 126 points
