Training & Technology Transfer Project Description May 18, 1994 - September 30, 1996 Engineering Scale-Up of In Situ Bioremediation Processes: A Process Guideline for Biotreatability A.B. Cunningham, B.K. Warwood, and N. Zelver, Montana State University Goals: The goal is to provide a protocol for comprehensive biotreatability site evaluation. Rationale: Bioremediation is the application of microbial processes to remove or degrade contaminating substances from soil, ground water, or bodies of water. While this method of remediation is often used, it seldom fulfills expectations. Lack of proper site evaluation is usually the basis for this deficiency. Approach: The biotreatability evaluation document will incorporate and describe successful methodologies for evaluating site biodegradation kinetics and mass transport parameters. It will also serve as a guideline for in situ biotreatability work plan development and evaluation and be the basis for a design protocol. This document will be developed during the first year and a workshop for industrial representatives will be developed and presented during the second year. Status: In the second year of this project, investigators worked to condense information previously published in the review paper into an effective workshop for practitioners needing to make decisions regarding in situ bioremediation. The project team presented a workshop to an audience of state regulators and consultants. The workshop was directed at presenting concepts and methodologies to facilitate improved decision making relative to bioremediation of ground water and soil. A similar workshop was also presented at the HSRC/WERC Joint Conference on the Environment in May 1996. Additional presentations were made in late 1996. This project has been completed. Clients/Users: Engineers, university faculty members, and members of industry will be interested in this project. Key words: bioremediation, engineering scale-up, biotreatability, in situ.
