Peer Review for EPA’s Proposed Approaches to Inform the Derivation of a Maximum Contaminant Level Goal for Perchlorate in Drinking Water (PUBLISHED REPORT)
EPA is developing approaches to inform the derivation of a Maximum Contaminant Level Goal (MCLG) for perchlorate in drinking water under the Safe Drinking Water Act. EPA previously conducted an independent, external, scientific peer review of the draft biologically-based dose-res...
User's Manual: Co-Digestion Economic Analysis Tool (PUBLISHED REPORT)
Many WRRFs have anaerobic digestion (AD) systems that have excess capacity, sometimes significant excess capacity. This is often a result of changes in service area population not rising to match design expectations. Having AD capacity could be an opportunity to create or enhan...
PCB transport and fate modeling at New Bedford Harbor, MA (PUBLISHED REPORT)
The post-remediation scenario selected by USEPA was constructed in the LTFATE modeling system that was used to perform this modeling study as follows: a) The bathymetry in the NBH portion of the model domain was updated using the latest bathymetric survey provided by EPA; b) In t...
Post-Closure Performance of liner Systems at RCRA Subtitle C Landfills (PUBLISHED REPORT)
In general, field data showed a decline in leachate flow from the LCRS and LDS. In all cases, placement of cover led to a reduction in the LCRS flow rate, including where only 12 inches of intermediate cover soil had been placed. Rainfall has an effect on leachate generation, wit...
Key Earth System Science Objectives Related to Land Surface Phenomena (PUBLISHED REPORT)
This paper addresses United States Environmental Protection Agency (EPA) operational and research challenges for the next decade in the utilization of space-based observations for the assessment of terrestrial properties affecting land, water, and air resources, and human health....
Key Earth System Science Water Quality Objectives (PUBLISHED REPORT)
Water quality is essential for the survival of life, population health and well-being. No current or planned earth orbiting mission is optimized for water quality measures of inland waters (lakes and reservoirs) or estuaries. A combined science- and application- driven, long-term...
Monitoring Coastal and Wetland Biodiversity From Space (PUBLISHED REPORT)
The grand challenge of our time, in the face of the increasing impact of humans on the environment and climate, is to derive actionable knowledge to ensure sustainable use of marine and coastal resources and a healthy global society.This grand challenge requires a focus on these ...

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...
