The most difficult and persistent obstacle to successful subsurface remediation is access to residual contaminants. The distribution of residual contamination is heterogeneous by nature and accurate mapping is generally limited by the technological capability of tools and available funding for characterization. In addition, contamination is often found in a mixed zone of unsaturated, partially saturated, and saturated sediments. As a result, technology wish lists include treatment that can address contamination at the cubic centimeter scale with sufficient speed to treat hundreds of cubic meters per day - and in a cost-effective manner.  The soil blending process can homogenize the target area sufficiently to allow significantly improved contact of treatment with contaminants. Over the last decade, Redox Tech has completed numerous soil blending projects treating a variety of contaminants in a diverse suite of geologic environments. Many projects have dealt with recalcitrant contaminants in difficult settings. Soil blending has become a favorable alternative to dig-and-haul because it is viewed as more “green” and not a relocation of waste. 

There are currently two main types of soil mixing equipment: large diameter augers and rotary drum blenders. Large diameter augers (ranging to 8-10 feet in diameter) are typically mounted and operated in a similar manner to conventional drilling rigs. Their strength lies in the ability to mix to great depths, but are not efficient at covering large areas. Rotary drum blenders are typically mounted at the end of excavators and can rapidly address large areas, but are often limited in their depth. A key component of all soil blending equipment is the ability to effectively deliver power to the mixing head. Most commercially available rotary drum systems are not able to provide the power necessary to thoroughly mix cohesive materials like silts and clays. 

We will present excerpts from case studies where we have used combinations of soil blending and chemical reagents to remediate contaminated soil and groundwater. Examples will include direct chemical oxidation, enhanced aerobic and anaerobic biological oxidation, chemical and biological enhanced reduction, and stabilization techniques for both treatment and soil improvement. 

John Haselow received his PhD in Chemical Engineering from Purdue University in 1988. He has 29 years experience in the environmental field. From 1988 to 1995, Dr. Haselow was a research engineer/manager at the Savannah River National Laboratory (SRNL) in Aiken, South Carolina. In 1995, Dr. Haselow founded Redox Tech, a specialty environmental remediation company, which is headquartered in Cary, North Carolina. Dr. Haselow has been involved in over 2,000 environmental remediation projects involving chemical oxidation, bioremediation, metals stabilization, and soil blending.
