Evaluating the Progress of Natural Attenuation in Groundwater This course presents a simple, statistically based approach for evaluating the progress of natural attenuation from the data collected during site characterization and long term monitoring. The course also provides an approach to establish the time that should be required to attain the cleanup goals, and an…
Protocol for In-Situ Bioremediation of Chlorinated Solvents Using Edible Oil This course was developed to presents a technical protocol for designing and implementing in-situ bioremediation cleanup strategies at chlorinated solvent sites using edible oil. Management of groundwater contaminated with chlorinated solvents is one of the Department of Defense’s (DoD’s) greatest environmental challenges. Because of their…
Introduction to In Situ Bioremediation of Groundwater This course is an introduction to in situ bioremediation of groundwater and is intended to provide a reference on in situ groundwater bioremediation to designers and practitioners. In situ bioremediation (ISB) of groundwater involves the encouragement of indigenous bacterial populations to metabolize target contaminants through the addition of…
LNAPL Transport and Fate in the Subsurface This course presents best-practice guidance for the assessment and remediation of light non-aqueous phase liquids (LNAPLs) in the subsurface. LNAPLs notably include fuels and oils, and are amongst the most commonly encountered organic contaminants in the subsurface environment due to their ubiquitous use, accidental release and, poor management….
Design Considerations for Enhanced Reductive Dechlorination Chlorinated solvents in groundwater remain a key issue at contaminated sites, and enhanced reductive dechlorination (ERD) is a frequently selected remedy for treatment of these solvents. This course provides a framework for preparing design submittals for ERD systems, including a summary of best practices for bioremediation design, tips for…
Design Considerations for In Situ Chemical Oxidation Most in situ remediation systems including in situ chemical oxidation (ISCO) are less mature than ex situ remediation systems (e.g., pump and treat) and other conventional environmental systems (e.g., wastewater treatment systems); therefore, design information, formats, and standards for in situ remediation systems are generally not as readily…
