Source water quality impacts on drinking water treatment plant performance and disinfection byproduct formation during a storm event - 3/18/18 (PRESENTATION)
Future climate variability and land use changes can significantly impact organic matter (OM) contents of drinking water sources, thus affecting both the efficacy of water treatment unit processes and the formation potential for disinfection byproducts such as trihalomethanes (THM...
Predicting patterns of vulnerability to climate change in near coastal species using an algorithm-based risk assessment framework (PUBLISHED REPORT)
Near-coastal (0-200 depth) ecosystems and species are under threat from increasing temperatures, ocean acidification, and sea level rise. However, species vary in their vulnerability to specific climatic changes and climate impacts will vary geographically. For management to resp...
Evaluating Relationships Between Total Dissolved Solids (TDS) and Total Suspended Solids (TSS) in a Mining-Influenced Watershed (JOURNAL)
Measurement of total suspended solids (TSS) and total dissolved solids (TDS) loadings in streams is often used to assess potential impacts from mining on surface water quality within a drainage basin. It has been suggested that TSS could be used as an indicator to estimate TDS l...
Understanding the Impact of Mesh on Tank Overflow System Capacity (PRESENTATION)
This product is an abstract, to be submitted for consideration at the AWWA ACE conference for 2018. The abstract outlines the planned scope of a presentation that would be given at ACE 2018 if accepted.
Green Infrastructure at the Edison Environmental Center - Permeable Pavement (PRESENTATION)
The project involves green infrastructure research at the Edison Environmental Center (EEC). In 2009, EPA constructed a parking lot at the EEC comprised of permeable interlocking concrete pavers, pervious concrete and porous asphalt. Rain gardens adjacent to the parking lot infi...
Overview of EPA/WED Research on Water Quality and Coastal Ecosystems in Tillamook Basin and Coastal Recreational Ecosystem Goods and Services (EGS) in Tillamook Bay (PRESENTATION)
This is a briefing to the new director of Tillamook Estuaries Partnership to 1) summarize recent research on nutrients, fecal bacteria, acidification, watershed modeling, and shellfish habitats, and 2) introduce a new project to assess people's recreational use of estuarine ecosy...
Historical Trends of Benthic Invertebrate Biodiversity Spanning 182 Years in a Southern New England Estuary (JOURNAL)
Benthic invertebrates support numerous ecosystem functions and services including shellfish production, energy flow to fishes, and biogeochemical cycles. The decline of marine biodiversity worldwide has raised concerns about effects on ecosystems. To examine biodiversity trends o...
Identifying Clean and Sustainable Water Solutions Through Modeling, Mesocosms, and Muddy Boots (PRESENTATION)
Land use and environmental stressors, such as drought and deteriorating water infrastructure, can accelerate the depletion of freshwater resources that support humans and ecosystem services. As global demand for water and environmental stressors increase, the quality and availab...
Assessing estuary condition using Chiu’s Latent Health Factor Index (PRESENTATION)
Effective management of estuaries requires a comprehensive assessment of estuary condition. However, data available for such an assessment is often comprised of limited and disparate measures collected at point locations. A traditional approach is that specific metrics, such as...
Stream mesocosm phosphorus dose-response validation study (PRESENTATION)
Validating stream nutrient targets for water quality management with experiments that can demonstrate causal effects on biota lends confidence to the users and stakeholders of such targets. Numeric nutrient thresholds are based on correlation-type analyses using data from multipl...
Projecting Regional Climate Change for Air Quality and Water Quality Applications (PRESENTATION)
A presentation summarizing US EPA's dynamical downscaling research, its purpose and potential applications.
Overview of HABs Research Program (PRESENTATION)
This presentation is an overview of the cyanobacteria/harmful algal blooms research currently being performed within the Office of Research and Development's Safe and Sustainable Water Resources research program. The presentation highlights results in the following areas: lake m...
EPA’S EnviroAtlas: Indicators for Working Watersheds (PRESENTATION)
Over recent decades the government has made a wealth of information publicly available as part of the Federal Open Data Policy. The EnviroAtlas provides a wealth of geospatial data and other resources to decision makers, educators, and researchers. EnviroAtlas resources are organ...
Joint Agency Opportunities in the Science and Management of 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...
Efficacy of Inactivation of Pseudomonas aeruginosa by Multiple-Wavelength UV LEDs (PRESENTATION)
Pseudomonas aeruginosa is one of three major opportunistic premise plumbing pathogens (OPPPs). It is responsible for causing many types of infections including pneumonia and blood, tissue, and bone infections. In the United States, the most common disinfection practice for treatm...
Solar Energy Powers Remote Water Systems (JOURNAL)
Solar power is a viable renewable energy source for Puerto Rico due to the consistent sunshine and the high cost associated with importing other energy sources. U.S. EPA (EPA) and the InterAmerican University of Puerto Rico (IUPR) collaborated on a one-year project to design and...
Life Cycle Assessment and Cost Analysis of Membrane Bioreactor Systems: Influence of Scale, Population Density, Climate, and Methane Recovery (PRESENTATION)
Within the context of an urban case study, a life cycle assessment (LCA) and cost analysis were constructed to understand impacts associated with scenarios for mixed wastewater and greywater recycling. The technology of focus was an aerobic membrane bioreactor (MBR) of varying sc...
Disinfection of Wastewater with Peracetic Acid and UV Combined Treatment: A Pilot Study (PRESENTATION)
UV irradiation is one of the most commonly used wastewater disinfection methods for muncipal waste water disinfection. Significant advantages of using the UV-based disinfection are that it leaves no residual and does not form any disinfection by products (DBPs) in the treated was...
Nitrogen uptake and allocation estimates for Spartina alterniflora and Distichlis spicata (JOURNAL)
