Soil blending is an aggressive remedial technique that requires a focus of resources (equipment, personnel, and usually amendment) on a particular contaminated volume. It is often performed under time critical remediation drivers like property transfer and rapid construction, which will limit subsequent access to a site for additional cleanup or polishing. As a result, the remediation strategy must be reliable, fast, and comprehensive. The effective rate of reaction (kinetics) of the applied amendment is vital to the success of the cleanup. In addition to successful resolution of contamination, recovery of the site for future use (e.g., commercial/residential buildings, sports fields, etc.) after soil blending can be as important as the cleanup. There are several ways to recover the original or even improve soil strength and other site properties to rapidly enable the future use goals for the site. Concepts and case studies are presented.
