An Introduction to In-Situ Treatment of Hazardous Soil

COURSE NO: C02-059
An Introduction to In-Situ Treatment of Hazardous Soil
Course Highlights

This online engineering PDH course presents methods and technologies for treatment of contaminated soil in situ without substantive excavation of the soil.


Various in-situ technologies are applied for the treatment of contaminated soil in both the vadose zone and saturated and unsaturated source zones. These technologies involve applying chemical, biological, or physical processes to the subsurface to degrade, remove, or immobilize contaminants without removing the bulk soil. Compared to excavation and ex situ treatment, the use of these technologies offers several benefits, such as addressing deep contamination and costing less in general.


This 2 PDH course is intended for civil and environmental engineers as well as other design and construction professionals interested in learning about the principles of in-situ hazardous soil treatment.
