The LNAPLs (Light Non-Aqueous Phase Liquids) training courses help users set appropriate LNAPL remedial objectives in the context of a site-specific LNAPL conceptual site model, provide tools to screen 17 LNAPL remedial technologies to identify an optimal LNAPL remedial technology to achieve the objectives, and provide example performance metrics that would be set to gauge remedial effectiveness and demonstrate achievement of the objectives. Natural source zone depletion (NSZD) for LNAPLs is also summarized, including the processes involved, their rates, and potential for long-term progress.
The Biofuels training course addresses the causes and prevention of post-manufacture biofuel releases, impacts to environmental media, characterization methods, remedial responses, and stakeholder concerns.
The training course helps dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. These differences are the focus of this training.
The Mass Flux training course summarizes the concepts underlying mass flux and discharge, their potential applications, and case studies of the uses of these metrics.
Petroleum Vapor Intrusion (PVI) is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light non-aqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. This training course provides a comprehensive methodology for screening, investigating, and managing potential PVI sites.
This training course provides a holistic process for management of challenging sites, termed “adaptive site management.” This process is a comprehensive, flexible, and iterative process that is well-suited for sites where there is significant uncertainty in remedy performance predictions.
