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.

Project Overview

IET conducted a rapid environmental site assessment in Gaffney, South Carolina using direct push probe rig technology. The investigation involved multi-depth soil sampling to characterize shallow and deeper subsurface conditions for an environmental consultant's Phase II assessment.

Scope of Work

10 shallow soil samples collected to 5 feet below ground surface
3 deeper samples advanced to 15 feet for vertical profiling
19 sample liners provided for continuous sample preservation
Probe point abandonment with bentonite/cement grout materials
Single-day project completion for cost-effective rapid assessment

Technical Approach

Direct Push Probe Rig

IET's probe rigs efficiently advance sampling tools to target depths without drill cuttings generation. This method provides rapid, cost-effective site characterization ideal for Phase II environmental assessments.

Multi-Depth Sampling

The investigation design incorporated both shallow (5 feet) and deeper (15 feet) samples to assess vertical contaminant distribution and define the extent of any potential impacts.

Sample Preservation

Soil samples were collected in dedicated sample liners to maintain sample integrity and prevent cross-contamination during transport to the analytical laboratory.

Proper Abandonment

All probe points were properly abandoned with bentonite/cement grout mix to prevent any vertical migration pathways and ensure regulatory compliance with SC DHEC requirements.
