Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Video Archives

Sites contaminated by chlorinated solvents present a daunting environmental challenge, especially at sites with dense nonaqueous phase liquid (DNAPL) still present. Restoring sites contaminated by chlorinated solvents to typical regulatory criteria (low parts-per-billion concentrations) within a generation (~20 years) has proven exceptionally difficult, although there have been successes...

The sediments underlying many of our nation?s major waterways are contaminated with toxic pollutants from past industrial activities. Cleaning up contaminated sediments is expensive and technically-challenging. Sediment sites are unique, complex, and require a multidisciplinary approach and often project managers lack sediments experience...

The Office of Superfund Remediation and Technology Innovation (OSRTI) is offering a training webinar on the recent "Pre-CERCLA Screening Guidance" issued by the U.S. Environmental Protection Agency (EPA) in December 2016. This guidance is used by EPA, State, and Tribal Superfund site assessment staff and support contractors when deciding if a new site should be added to the Superfund "active site inventory" for more thorough pre-remedial site evaluation...

Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur...

This webinar is part of a series featuring presentations delivered at the May 2017 Federal Remediation Technologies Roundtable Meeting. This meeting focused on the characterization and treatment of heavy metals at mining sites. More information about the meeting can be found at https://frtr.gov/meetings1.htm. This webinar will focus on techniques that can be implemented for site characterization and modelling...

This webinar will focus on different techniques that can be implemented for site characterization and bioremediation. Aqueous Geochemical Modeling can be used to evaluate the cost effectiveness and feasibility of treatment strategies for metal-laden discharges from coal and metal mines. Best practices for monitoring and modeling Anaerobic biochemical reactors (BCR) will be described as it relates to bioremediation of mining sites...

Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation...
