In Situ Bioremediation Training Courses

ITRC Documents Associated with this Topic

The In Situ Bioremediation (ISB) training courses address the systematic characterization, evaluation, and appropriate design and testing of ISB for biotreatable contaminants.

Enhanced In Situ Bioremediation of Solvents in Groundwater

Enhanced In Situ Bioremediation (EISB) systems designed to remediate chlorinated solvents in groundwater involve input of an organic source, nutrients, electron acceptors, and/or microbial cultures to stimulate degradation. EISB systems may be used to remediate high concentration areas within plumes or source areas, to help provide containment of a chlorinated solvent plume, or as part of a treatment train down gradient from a primary cleanup or containment system.

This training is designed to introduce state regulators, environmental consultants, site owners, and community stakeholders to the document created by the ITRC's In Situ Bioremediation Technical Team and the Remediation Technologies Development Forum (RTDF) Bioremediation Consortium titled, Technical & Regulatory Guidance for Enhanced In Situ Bioremediation of Chlorinated Solvents in Groundwater (ISB-6, 1998). The training focuses on a variety of amendments, which may be added to in situ bioremediation systems, the mechanism of delivery, and regulatory issues associated with approving or permitting EISB systems. This training includes discussion of common problems encountered during operation of a system.

Systematic Approach to In Situ Bioremediation in Groundwater: Nitrates, Carbon Tetrachloride & Perchlorate

Several aspects of in situ bioremediation (ISB) are characteristic of all sites, no matter what contaminant is being scrutinized. Many site characteristics used to determine the efficacy of ISB are also similar, even though contaminants and breakdown products differ. Once a site has been characterized for ISB efficacy and the contaminants of concern and degradation products have been defined, engineered approaches can be designed, pilot-tested, and possibly deployed.

This training presents a decision tree for reviewing, planning, evaluating, and approving in situ bioremediation (ISB) systems in the saturated subsurface. It defines site parameters and appropriate ranges of criteria necessary for characterization, testing, design, and monitoring of ISB technologies. The course is based on ITRC's Systematic Approach to In Situ Bioremediation: Nitrates, Carbon Tetrachloride, and Perchlorate (ISB-8, 2002), which describes information needed for any ISB evaluation, provides a flow diagram defining primary decision points, and discusses characteristics used to evaluate monitored natural attenuation or enhanced ISB application as remediation options. It includes examples of how to apply the document, with additional decision trees for nitrate, carbon tetrachloride, and perchlorate.
