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

Surface water bodies adjacent to sites with contaminated groundwater may receive impacts that impair otherwise functional ecosystems and create new exposure pathways, increasing human health risks. Optimizing site characterization protocols to improve the remedy design effort is best achieved by developing knowledge of the potential extent and magnitude of contaminated groundwater discharge into the surface water body...

This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees from University of Louisville, University of New Mexico, and University of Washington will describe their research projects, accomplishments, and next steps. The University of Louisville SRP Center studies the cardiometabolic effects of volatile organic chemicals (VOCs) that are of high relevance to human health...

The U.S. EPA Environmental Response Team's (ERT) Trace Atmospheric Gas Analyzer (TAGA) mobile laboratories have been utilized for numerous and varied monitoring and analysis operations. Over the years, the TAGA laboratories have been employed at traditional emergency responses, including chemical plant explosions, train derailments, pipeline breaks, oil spills, floods, hurricanes, etc...

Vapor intrusion has been a topic of intense interest in the United States for the recent past. The concern that the vapor intrusion pathway poses is whether an unacceptable risk exists for the occupants. To determine the risk associated with the vapor intrusion pathway, confounding factors due to the presence of these chemical from other sources need to be qualitatively and quantitatively identified so that the contributions from the vapor intrusion alone can be assessed...

This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees from Duke University and University of Arizona will describe their research projects, accomplishments, and next steps. The Duke University SRP Center focuses on early, low-dose exposures to toxicants and developmental impacts, which are usually evident only later in life...

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)...

Contractor performance metrics are measured by two blind seeding systems on Munitions Response (MR) projects - Quality Assurance and Quality Control. Quality Assurance (QA) seeding is the primary quality system used by the Government to independently check the Contractor's performance at MR sites. QA seeding consists of Government personnel (or a third-party QA Contractor) burying blind seeds at depths and in locations that allow for easy detection...

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...
