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…
LNAPL Site Management Light Non-aqueous Phase Liquid (LNAPL) contaminated sites can be very challenging to assess, remediate, and ultimately close out due to both technical and regulatory issues. Therefore, it is essential to develop a strategic action plan early in the process to establish goals, specify a remedy, and chart a clear course to achieve…
Flint and Lead: The Water-Public Health Connection This On-Demand webinar discusses the current state of science related to the health risks posed by lead and the value of engaging the water systems sector. Reports of elevated blood lead levels in children in Flint, Michigan, placed a national spotlight on the role of drinking water in lead…
