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

EPA?s Office of Superfund Remediation and Technology Innovation (OSRTI) and the Environmental Response Training Program (ERTP) in conjunction with the Superfund Task Force will host this webinar on high resolution site characterization using direct-sensing and data visualization tools to rapidly build the conceptual site model in an adaptive process...

An innovative remedy at the Henry's Knob Superfund Alternative site is protecting public health and the environment while also serving as vital native habitat for pollinators and other species. The remedy was designed by Amec Foster Wheeler Environment and Infrastructure (Amec Foster Wheeler) for a Confidential Client who was one of the site?s responsible parties...

This webinar is part of a series featuring presentations delivered at the November 2017 FRTR Meeting. This meeting focused on remediation technologies for radionuclides and heavy metals in soil, ground water and sediments.

From cleanup to final settlement or leasing agreements, EPA plays a central role in facilitating the cleanup and redevelopment of contaminated sites by bringing together key parties. EPA works with stakeholders to negotiate settlement agreements, resolve competing liens and ensure future reuse is compatible with the cleanup...

Characterization and remediation of contaminated groundwater in fractured rock has not been conducted or studied as broadly as groundwater at unconsolidated porous media sites. This unfamiliarity and lack of experience can make fractured rock sites perplexing. This situation is especially true in portions of the U.S. where bedrock aquifers are a primary source of drinking and process water, and demands on water are increasing...

Successful remediation decisions at contaminated sites depend on the quality of the collected data, accuracy of data analysis, and interpretation of that data during site assessment and characterization. This webinar presents various case studies, which demonstrate how to apply HRSC strategies using direct sensing tools advanced using direct push technologies (DPT) and interpretive techniques to support and improve remediation decisions at sites...

Risk-based cleanup goals are often calculated assuming that chemicals present in soil are absorbed by humans as efficiently as the chemicals dosed during the toxicity tests used to determine regulatory toxicity values (such as the Reference Dose or Cancer Slope Factor)...

At some sites, complex site-specific conditions make it difficult to fully remediate environmental contamination. Both technical and nontechnical challenges can impede remediation and may prevent a site from achieving federal- and state-mandated regulatory cleanup goals within a reasonable time frame. For example, technical challenges may include geologic, hydrogeologic, geochemical, and contaminant-related conditions as well as large-scale or surface conditions...

Many state and local regulatory agencies responsible for the cleanup of chemicals released to the environment have adopted regulations, guidance and policies that define default approaches, scenarios, and parameters as a starting point for risk assessment and the development of risk-based screening values...
