Working with Tribes to Assess, Manage, and Improve Ecosystem Function through EPA’s Science to Achieve Results (STAR) Grants Program and Collaborative Research Projects (SUMMARY)
The summary demonstrates how tribes use traditional knowledge/Traditional Ecological knowledge and technical tools and support from EPA in addressing environmental concerns. We highlighted two projects where EPA worked directly with tribes to conduct Riparian Proper Functioning C...
Application of Climate Assessment Tool (CAT) to Estimate Climate Variability Impacts on Nutrient Loading from Local Watersheds (JOURNAL)
Many future climate scenario datasets, created by climate models such as general circulation models (GCMs), have been used in conjunction with watershed models to project future climate variability impact on hydrological processes and water quality. However, these low spatial-tem...
Groundwater Co-Contaminant Behavior of Arsenic and Selenium at a Lead and Zinc Smelting Facility (JOURNAL)
Co-contaminant behavior of arsenic (As) and selenium (Se) in groundwater is examined in this study at a former lead and zinc smelting facility. We collected water quality data, including concentrations of trace metals, major ions, and metalloid speciation, over a 15-year period t...
EPA Research on Estuarine Water Quality and Ecosystems for the Benefit of Pacific Coastal Communities (PRESENTATION)
This presentation describes EPA Research for a staff visit for Congressional Rep. Suzanne Bonamici (OR 1st District). It provides an overview of water quality and ecosystem services research by the EPA at the Western Ecology Division. This presentation is given in conjunction wit...
EPA Research To Support Sustainable Green Infrastructure Solutions In The Lick Run Watershed (PRESENTATION)
The EPA is collaborating with the Metropolitan Sewer District of Greater Cincinnati and its partners in Project Groundwork, on research for effective ways to use green infrastructure (GI) to achieve sustainable solutions to combined sewer overflows in the Lick Run Watershed. GI ...
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...
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...
Depressional wetlands affect watershed hydrological, biogeochemical, and ecological functions (JOURNAL)
Depressional wetlands of the extensive U.S. and Canadian Prairie Pothole Region afford numerous ecosystem processes that maintain healthy watershed functioning. However, these wetlands have been lost at a prodigious rate over past decades due to drainage for development, climate ...
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...
Individual-Based Modelling Approach to Thermal Refuge Use by Migrating Adult Salmon and Steelhead (PRESENTATION)
Diadromous fish populations in the Pacific Northwest face challenges along their migratory routes from declining habitat quality, harvest, and barriers to longitudinal connectivity. Changes in river temperature regimes are producing an additional challenge for upstream migrating ...
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...
