Characterizing Ohio River NOM Variability and Reconstituted-Lyophilized NOM as a Source Surrogate
(JOURNAL) [Published : Jan 01, 2017]
Surface water contains natural organic matter (NOM) that reacts with disinfectants creating disinfection byproducts (DBPs), some of which are USEPA regulated contaminants. Characterizing NOM can provide insight with respect to DBP formation and water treatment process adaptation...

Characterizing the impact of projected changes in climate and air quality on human exposures to ozone
(JOURNAL) [Published : Jun 01, 2017]
The impact of climate change on human and environmental health is of critical concern. Population exposures to air pollutants both indoors and outdoors are influenced by a wide range of air quality, meteorological, behavioral, and housing-related factors, many of which are also i...
Chemical transport model simulations of organic aerosol in southern California: model evaluation and gasoline and diesel source contributions
(JOURNAL) [Published : Mar 30, 2017]
Gasoline- and diesel-fueled engines are ubiquitous sources of air pollution in urban environments. They emit both primary particulate matter and precursor gases that react to form secondary particulate matter in the atmosphere. In this work, we updated the organic aerosol module ...
Climate change impacts on projections of excess mortality at 2030 using spatially varying ozone-temperature
(JOURNAL) [Published : Jan 18, 2017]
We project the change in ozone-related mortality burden attributable to changes in climate between a historical (1995-2005) and near-future (2025-2035) time period while incorporating a non-linear and synergistic effect of ozone and temperature on mortality. We simulate air quali...
Climate impacts on connectivity of snowmelt to flow in the Willamette River using water stable isotopes
(PRESENTATION) [Presented : May 03, 2017]
Much of the water that people in Western Oregon rely on comes from snowpack in the Cascade Range, and this snowpack is expected to decrease in coming years with climate change. In fact, the past 6 years have shown dramatic variation in snowpack, from a high of 174% of normal in ...
Community vulnerability to health impacts of wildland fire smoke exposure
(JOURNAL) [Published : Jun 20, 2017]
Identifying communities vulnerable to adverse health effects from exposure to wildfire smoke may help prepare responses, increase the resilience to smoke and improve public health outcomes during smoke days. We developed a Community Health-Vulnerability Index (CHVI) based on fact...
Considerations in linking energy scenario modeling and Life Cycle Analysis
(PRESENTATION) [Presented : Aug 18, 2017]
The U.S. EPA Office of Research and Development (ORD) has been exploring approaches for estimating U.S. anthropogenic air pollutant emissions through the mid-21st century. As a result, we have developed the Emission Scenario Projection methodology, or ESP. In this document, we pr...
Contrasting Decadal-Scale Changes in Elevation and Vegetation in Two Long Island Sound Salt Marshes
(JOURNAL) [Published : May 01, 2017]
Northeastern US salt marshes face multiple co-stressors, including accelerating rates of relative sea level rise (RSLR), elevated nutrient inputs, and low sediment supplies. In order to evaluate how marsh surface elevations respond to such factors, we used surface elevation table...
Coupling Computer-Aided Process Simulation and Estimations of Emissions and Land Use for Rapid Life Cycle Inventory Modeling
(JOURNAL) [Published : Mar 20, 2017]
A methodology is described for developing a gate-to-gate life cycle inventory (LCI) of a chemical manufacturing process to support the application of life cycle assessment in the design and regulation of sustainable chemicals. The inventories were derived by first applying proces...
Cross-scale interactions affect tree growth and intrinsic water use efficiency and highlight the importance of spatial context in managing forests under global change
(JOURNAL) [Published : Sep 01, 2017]
1. We investigated the potential of cross-scale interactions to affect the outcome of density reduction in a large-scale silvicultural experiment. 2. We measured tree growth and intrinsic water-use efficiency (iWUE) based on stable carbon isotopes (13C) to investigate the...
Decision Support System for Aquifer Recharge (AR) and Aquifer Storage and Recovery (ASR) Planning, Design, and Evaluation - Principles and Technical Basis
(PUBLISHED REPORT) [Published : Feb 20, 2017]
Aquifer recharge (AR) is a technical method being utilized to enhance groundwater resources through man-made replenishment means, such as infiltration basins and injections wells. Aquifer storage and recovery (ASR) furthers the AR techniques by withdrawal of stored groundwater at...
Detecting spatial regimes in ecosystems
(JOURNAL) [Published : Jan 01, 2017]
Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological ...
