Course examines how to determine best bioremediation approach for chlorinated solvents (May 2, 2011)

(WESTERVILLE, OH — April 29, 2011) A course on bioremediation approaches for chlorinated solvents will take place May 5-6 in Baltimore, Maryland, concurrent with the end of the National Ground Water Association’s 2011 Ground Water Summit.

A number of different bioremediation approaches are available to treat sites contaminated with chlorinated solvents. They include intrinsic bioremediation, biostimulation, and bioaugmentation. In addition, biologically mediated abiotic degradation has emerged as a viable remediation approach.

The efficacy of each approach is highly dependent on site conditions including types of contaminants, hydrogeology, geochemistry, and biology. It can therefore be difficult to accurately determine the best approach for a given site.

In this course, attendees will learn:

General microbiological concepts
How to screen sites for the applicability of enhanced bioremediation remedies
How to select the best bioremediation approach from a myriad of choices with respect to protection of human health, the environment, and cost (cost-benefit analysis)
The use of the most up-to-date analytical techniques coupled with a quantitative decision matrix to select the most effective bioremediation technology
Utilization and interpretation of analytical data including geochemical data, molecular biological analyses such as quantitative real-time polymerase chain reactions (qPCR), compound-specific isotope analyses, and VOC data
How to use recent advances in biogeochemical site characterization to select the most cost-effective and efficient bioremediation approach, thus avoiding the expenditure of unnecessary resources.

This course is best suited to regulators, hydrogeologists, environmental engineers, microbiologists, project managers, and graduate students.

The course instructors are:

Todd H. Wiedemeier, PG, president of T.H. Wiedemeier & Associates LLC, who has more than 14 years of experience in remediation. He's conducted natural attenuation and bioremediation feasibility studies at more than 100 sites contaminated with fuel hydrocarbons.
W. Zachary Dickson, who has more than 20 years of professional experience related to defining and understanding geologic and hydrogeologic systems, and defining and remediating environmental impacts.
