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.

Owensboro Six-Area Bioaugmentation Program

Owensboro, KY

September 2017

Six Areas

DHC & SRS Bioaugmentation

An environmental consulting firm contracted IET for a comprehensive bioaugmentation program across six distinct treatment areas. The program featured Dehalococcoides (DHC) and SRS bacterial cultures for reductive dechlorination, with extensive concrete coring (77 total cores) for interior access and full site restoration.

Treatment Areas

Area 3 (Largest — 6 days)

DHC and SRS bacterial cultures, 37 concrete cores for interior access

Area 1 (5 days)

DHC and SRS bacterial cultures, 30 concrete cores for interior access

Area 6

DHC and SRS bioaugmentation injection

Area 5

DHC and SRS bioaugmentation injection

Area 2

DHC and SRS injection, 5 concrete cores

Area 4

DHC and SRS injection, 5 concrete cores
