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.

Environmental Remediation in California — Frequently Asked Questions

Answers to common questions about IET's in-situ remediation and environmental drilling services across California.

What environmental remediation services does IET provide in California?

IET delivers in-situ chemical oxidation (ISCO), enhanced bioremediation, in-situ chemical reduction (ISCR), and environmental drilling across California — serving Los Angeles, San Francisco, San Diego, Sacramento, and communities statewide.

What contaminants does IET treat at California sites?

IET treats chlorinated solvents, petroleum hydrocarbons, and source-zone contamination using permanganate ISCO, activated persulfate, and bioremediation — including a source-area and permeable reactive barrier (PRB) permanganate program in Brea.

Can IET install permeable reactive barriers in California?

Yes. IET designs and installs permeable reactive barriers (PRBs) using variable-concentration permanganate and other reactive media, demonstrated at the Brea, CA source-area treatment program.

Does IET perform environmental drilling in California?

Yes. IET provides monitoring well installation, direct push sampling, and injection point installation across California for Phase II ESAs, groundwater monitoring, and remediation delivery.
