HAZARDOUS SOIL & GROUNDWATER TREATMENT
As part of our pledge to be “more than a contractor,” HEPACO strives to provide innovative approaches to meeting cleanup goals by the most economical means and methods possible. HEPACO has specialized expertise with several in-situ remediation technologies with an emphasis on safety, cost reduction, performance, and ease of use.
In-situ treatment of contaminated soil and groundwater can be achieved by various means and methods. Injection is a viable and effective process on many sites, especially for groundwater. The soil treatment method preferred by HEPACO involves in-situ mixing with excavation equipment and specialty mixing attachments. Because the contamination is treated directly within the impacted area (“in-situ”) prior to generation of a waste, this method is especially beneficial when addressing contamination levels in excess of hazardous waste standards.
When comparing in-situ mixing and treatment of soil to more traditional “hog and haul” methods of hazardous waste remediation, in-situ treatment achieves three simultaneous key objectives:
- It significantly reduces overall project costs.
- It is fast-acting.
- It prevents the generation of hazardous waste.
HEPACO utilizes various in-situ remediation technologies when addressing soil and groundwater contamination, including the following:
- In-situ chemical oxidation (ISCO)
- Metals stabilization/fixation
- Enhanced aerobic biodegradation
- Enhanced reductive dechlorination
