Procedure and Key Optimization Strategies for an Automated CapillaryElectrophoretic-based Immunoassay Method (PUBLISHED REPORT)
New technologies that utilize capillary-based immunoassays promise faster and more quantitative protein assessment compared to traditional immunoassays. However, similar to other antibody-based protein assays, optimization of capillary-based immunoassay parameters, such as protei...
Petroleum Vapor Intrusion Modeling Assessment with PVIScreen (PUBLISHED REPORT)
Vapor intrusion of petroleum compounds differs from that of chlorinated solvents because of the dominant effect of aerobic biodegradation on the concentration and distribution of petroleum vapors. To better understand the behavior of petroleum compounds, a model called PVIScree...
Drinking Water Treatment Source Water Early Warning System State of the Science Review (PUBLISHED REPORT)
Report
An Approach that Uses the Concentrations of Hydrocarbon Compounds in Soil Gas at the Source of Contamination to Evaluate the Potential for Intrusion of Petroleum Vapors into Buildings (PVI) (PUBLISHED REPORT)
If motor fuels are spilled from underground storage tanks, petroleum hydrocarbons can vaporize from the spill and move as a vapor through the unsaturated zone. If a building is sited above or near the spill, the hydrocarbons may intrude into the air space of the building. This ...
NIEHS/EPA Children’s Environmental Health and Disease Prevention Research Centers: Protecting Children’s Health Where They Live, Learn, and Play (PUBLISHED REPORT)
In 1997, EPA and the National Institute of Environmental Health Sciences (NIEHS) partnered to form the Children's Environmental Health and Disease Prevention Research Centers. This impact report summarizes the history of the program, scientific findings since the program's incept...
Threat Ensemble Vulnerability Assessment – Sensor Placement Optimization Tool (TEVA-SPOT) Graphical User Interface User’s Manual (PUBLISHED REPORT)
This report provides an updated User’s Manual for the Threat Ensemble Vulnerability Assessment – Sensor Placement Optimization Tool (TEVA-SPOT), graphical user interface (GUI) software program. The TEVA-SPOT software tool quantifies consequences from an array of contaminant-rele...
Scientific and Technical Advisory Committee Peer Review of Revised James River Chlorophyll-a Criteria and Assessment (PUBLISHED REPORT)
The report addresses three charge questions that were proposed by the CB STAC. The panel noted that concerns outlined in a previous review (also published by STAC) had been earnestly considered in the new effort and that the VADEQ is on a path that will lead to scientifically de...
EPA-USDA-USGS Working Meeting on Management Strategies for Reactive Nitrogen and Co-Pollutants (PUBLISHED REPORT)
Scientists and managers from government, academia, NGOs and the private sector came together in June 2014 to review the science and management related to reactive nitrogen and co-pollutants (e.g., phosphorus, sulfur) across the U.S. Department of Agriculture (USDA), U.S. Geologic...
2012 Annual Report to Characterize the Ottawa River Using Physical, Biological, and Chemical Lines of Evidence (PUBLISHED REPORT)
International concern about contaminated sediments is increasing as sustainable practices are needed to maintain water resources and waterways as important economic, commercial, recreational, and community resources. Sediments often serve as long-term sinks for legacy pollutants,...
