A simple, dynamic, hydrological model of a mesotidal salt marsh (PRESENTATION)
Salt marsh hydrology presents many difficulties from a modeling standpoint: the bi-directional flows of tidal waters, variable water densities due to mixing of fresh and salt water, significant influences from vegetation, and complex stream morphologies. Because of these difficu...
CMAQ modeling in the nitrogen inventory study in the Nooksack-Abbotsford-Sumas Transboundary Region (PRESENTATION)
Optimizing nitrogen (N) use for food production while minimizing the release of N and co-pollutants to the environment is an important challenge. The Nooksack-Abbotsford-Sumas Transboundary (NAS) Region, spanning a portion of the western interface of British Columbia, Washington...
Water recovery from brines and salt-saturated solutions: operability and thermodynamic efficiency considerations for desalination technologies (JOURNAL)
This review provides an overview of desalination technologies and discusses the thermodynamic efficiencies and operational issues associated with the various technologies particularly with regard to high salinity streams. When water is recovered from a saline source, a brine conc...

Peer Review for EPA’s Proposed Approaches to Inform the Derivation of a Maximum Contaminant Level Goal for Perchlorate in Drinking Water (CRITERIA DOCUMENT)
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...
Peer Review for EPA’s Biologically Based Dose-Response (BBDR) Model for Perchlorate (CRITERIA DOCUMENT)
EPA is developing a regulation for perchlorate in drinking water. As part the regulatory process EPA must develop a Maximum Contaminant Level Goal (MCLG). FDA and EPA scientists developed a biologically based dose-response (BBDR) model to assist in deriving the MCLG. This mode...
Holistic blue water use and life cycle cost savings of domestic and agricultural rainwater harvesting at the watershed scale in the Southeast US (PRESENTATION)
According to the U.S. Global Change Research Program, from 1970 to 2007 most of the Southeast U.S. received heavy downpours in recent autumns while moderate-to-severe drought increased in spring and summer (12% and 14%). Rainwater harvesting (RWH) is getting attention due to rece...
Sustainability analysis and life-cycle ecological impacts of rainwater harvesting systems using holistic analysis and a modified eco-efficiency framework (PRESENTATION)
Background/Question/Methods A sustainability paradigm is being recognized globally as a path forward for human prosperity and ecological health in the face of climate change and meeting challenges of the water-energy-food nexus. Rainfall shortages for drinking water and crop pro...
Removal of Strontium by Ion Exchange and Lime Softening (PRESENTATION)

An Ultra-Sensitive Method for the Analysis of Perfluorinated Alkyl Acids in Drinking Water using a Column Switching High-Performance Liquid Chromatography Tandem Mass Spectrometry (JOURNAL)
In epidemiological research, it has become increasingly important to assess subjects' exposure to different classes of chemicals in multiple environmental media. It is a common practice to aliquot limited volumes of samples into smaller quantities for specific trace level chemi...
Efforts to estimate pesticide degradation rates in subsurface vadose and aquifer materials (PRESENTATION)
When pesticides are used in real-world settings, the objective is to be effective in pest eradication at the site of application, but also it is desired that the pesticide have minimal persistence and mobility as it migrates away from the application site. At the site of applicat...
