Early-life Exposures - Long-term Health Consequences: Part 1 Brominated Flame Retardants - February 3, 2012, 1:00PM-3:00PM EST (18:00-20:00 GMT).
This series "Early-life Exposures - Long-term Health Consequences" features SRP research in revealing the vulnerability of a developing child by identifying how biological systems are disturbed in this early period of life. The series will showcase cutting edge research findings that illuminate the consequences of early life exposures to metals and organic contaminants of emerging concern. The first session "Early-life Exposures - Long-term Health Consequences: Part 1 Brominated Flame Retardants" features Dr. Linda Birnbaum (Director, National Institute of Environmental Health Sciences), Dr. Heather Stapleton (Duke University) and Dr. Prasada Kodavanti (US EPA). The seminar will feature work with brominated flame retardants, compounds that are frequently added to consumer products (such as furniture and electronics) to improve fire safety. Polybrominated flame retardants (PBDEs) can cross the placental barrier from mother to fetus and influence childhood development years later. PBDEs have been associated with alterations in thyroid hormone levels, reduced fertility, and neurodevelopmental deficits. Dr. Stapleton will present a recent study exploring the association between PBDEs exposure measured in serum levels and thyroid hormone levels among a cohort of pregnant women. Additionally, she will highlight new research insights into possible mechanisms of thyroid hormone dysregulation. Dr. Kodavanti will discuss a study evaluating the neurobehavioral, hormonal, and reproductive effects of perinatal exposure to a commercial PBDE mixture, DE-71, in a population of rats. PBDE was demonstrated to cross the blood-placenta and blood-brain barriers, resulting in subtle changes in some parameters of neurobehavior, dramatic changes in thyroid hormone levels, and alterations in both male and female reproductive endpoints. The seminar will be moderated by Dr. William A. Suk, Director of the Superfund Research Program at NIEHS. For more information and to register, see http://clu-in.org/live .

Decision Trees for Screening Potentially Contaminated or Underutilized Site for Solar and Wind Potential - February 7, 2012 1:00PM-2:30PM EST (18:00-19:30 GMT). This webinar will give an overview of two draft decision trees that the Environmental Protection Agency (EPA) and National Renewable Energy Laboratory (NREL) created to screen potentially contaminated and underutilized sites for solar and wind potential. These decision trees were created to guide state and local governments and other stakeholders through a process for screening sites for their suitability for solar photovoltaic (PV) and wind energy. Targeted sites include underutilized "greyfields", commercial/industrial rooftops, brownfields, Superfund sites, RCRA sites, publicly owned facilities, abandoned parcels, and landfills. EPA encourages the development of these targeted sites, instead of green space.

New CLU-IN Mass Flux Focus Area. Most decisions regarding contaminated groundwater sites are driven by contaminant concentrations. These decisions can be improved by also considering contaminant mass discharge and mass flux. Mass discharge and flux estimates quantify source or plume strength at a given time and location. Consideration of the strength of a source or solute plume (i.e., the contaminant mass moving in the groundwater per unit of time) improves evaluation of natural attenuation and assessment of risks posed by contamination to downgradient receptors, such as supply wells or surface water bodies.

Green Remediation Best Management Practices: Landfill Cover Systems & Energy Production (EPA 542-F-11-024). The U.S. Environmental Protection Agency (EPA) Principles for Greener Cleanups outline the Agency's policy for evaluating and minimizing the environmental footprint of activities undertaken when cleaning up a contaminated site. Use of the best management practices (BMPs) recommended in EPAs series of green remediation fact sheets can help project managers and other stakeholders apply the principles on a routine basis while maintaining the cleanup objectives, ensuring protectiveness of a remedy, and improving its environmental outcome. Remediation at thousands of sites across the United States involves hazardous waste from former industrial landfills or waste piles, aged municipal landfills, or illegal dumps. A cover system is commonly installed at these areas as part of proper closure to serve as a surface barrier that contains the source material, reduces contaminant exposure or migration, and manages associated risk. The environmental footprint of activities needed to install and maintain a cover system can be reduced by adhering to EPA's Principles for Greener Cleanups (December 2011, 6 pages).

Optimization Evaluation: Lee Chemical Superfund Site, City Of Liberty, Clay County, Missouri (EPA 542-R-11-013). The Lee Chemical Superfund Site (site) is located along Missouri Highway 210 in Liberty, Missouri, approximately 15 miles east of Kansas City, Missouri. Currently, the site is a vacant lot of approximately 2.5 acres in a flat alluvial plain. The City of Liberty (City) has a municipal well field located approximately 0.40 miles southeast of the site. There are nine municipal water wells situated in a north-south line in the alluvial aquifer at an approximately perpendicular angle to the site. Historically, the City leased the land to the Lee Chemical Company, but then filed suit against Lee Chemical Company in 1975 for nonpayment of rent. The City then found and removed approximately 300 abandoned 55-gallon drums containing chemicals and wastes. In 1979, low levels of trichloroethene (TCE) were detected in the public water supply wells. Subsequent EPA and State investigations revealed contaminated groundwater and soil, and in 1982 the City and State identified the site as a source of TCE contamination in the public water supply. The current remedy in place for the Lee Chemical Superfund Site consists of the operation of an in situ aqueous soil washing system, the extraction of groundwater from extraction wells (EX) EX-1 and PW-2, and the discharge of the extracted groundwater from both extraction wells to a single, permitted outfall to Town Branch Creek. This Remedial Action (RA) is continually monitored and reported on through monthly and quarterly progress reports. The site remedy was considered Operational and Functional (O&F) on March 26, 1994. Recommendations are provided to improve remedy effectiveness, provide technical improvement, and gain site closure (December 2011, 69 pages). View or download at http://clu-in.org/techpubs.htm .

Optimization Review: Palermo Wellfield Superfund Site, City of Tumwater, Thurston County, Washington (EPA 542-R-11-010). The Palermo Wellfield Superfund Site (Site) is located near Interstate Highway 5 and Trosper Road in Tumwater, Washington. The Site includes a City-operated water-supply wellfield and an adjacent residential neighborhood in the Deschutes River Valley (sometimes referenced in site documents as the Palermo Valley), as well as upland source areas including the current Washington State Department of Transportation (WSDOT) Materials Testing Laboratory (MTL), a former WSDOT MTL, and the Southgate Dry Cleaners business. Trichloroethene (TCE) was detected in the City water supply at the wellfield in 1993. Subsequent investigations identified a TCE groundwater plume over 3,000 feet (ft) long and 600 ft wide, and a smaller tetrachloroethene (PCE) plume near the Southgate Dry Cleaners site. USEPA Region 10 nominated the Site for an optimization review due an interest in updating the conceptual site model (CSM) and concerns regarding plume migration control and the potential for vapor intrusion (VI) (January 2012, 152 pages).

Draft Solar and Wind Decision Trees. As part of EPA's RE-Powering America's Land Initiative, EPA and DOE's National Renewable Energy Lab (NREL) have worked together to create a tool that could be used nationally to screen sites for solar and wind production. While the decision trees focus on potentially contaminated sites, this tool also provides information on rooftop and other applications in order to support complimentary evaluations. These decision trees can be used to screen individual sites for their solar or wind potential or for a community-scale evaluation of multiple sites. These trees are not intended to replace or substitute the need for a detailed site-specific assessment that would follow an initial screening based on criteria contained in the tree. Tips on how users can obtain information relevant to various parameters in the tree are provided. EPA is seeking your feedback on these draft decision trees by February 16, 2012.
