Relationships between Private Domestic Wells and Underground Storage Tanks: Evaluation of Mapping and Plume Transport Tool Implementations (PUBLISHED REPORT)
Well water from private domestic wells (hereafter private wells) is often not tested as private owners are exempt from sampling requirements of the Safe Drinking Water Act. Numerous incidents of contamination of water in private wells have been reported, however. Potential cont...
Water Use Patterns in a Small Southern Oklahoma City During Drought and Implications for Leaking Underground Storage Tanks (PRESENTATION)
The City of Ada Oklahoma obtains water from the Simpson-Arbuckle aquifer located 19 km south of town. During winter the typical water demand is approximately 15,000 m3 per day, while during the drought of 2011 demand more than doubled. In order to understand water use patterns,...
Arsenic Concentrations in Drinking Water and Associations with Bladder Cancer Incidence, Accounting for Population Served (PRESENTATION)
Drinking water concentrations from community water systems (CWS) have been used to estimate county-level exposure to contaminants, such as arsenic. Many studies neglect to account for how exposure may differ within counties based on population served (PS) by a CWS. Accounting for...
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...
Hydrologic Performance of Retrofit Rain Gardens in a Residential Neighborhood (Cleveland Ohio USA) with a Focus on Monitoring Methods (PUBLISHED REPORT)
Green infrastructure refers to a range of urban stormwater management tools that can be flexibly implemented. These practices can aid in mitigating the negative impacts of runoff by increasing catchment detention capacity. We studied two engineered rain gardens (Cleveland OH) tha...
Tracking flows of water through a complex urban system: Chicago (PRESENTATION)
Urban water systems are complex and tightly coupled. In Chicago, the third largest US city, wastewater treatment plant (WWTP) effluent comprises up to 70% of streamflow, more than half of which is withdrawn for thermoelectric power generation (PG). Despite the interdependence o...
Aggregation of reduced graphene oxide and its nanohybrids with magnetite and elemental silver under environmentally relevant conditions (JOURNAL)
The aggregation and long-term (25 d) sedimentation behaviors of reduced graphene oxide (RGO) and its three successively self-assembled nanohybrids with magnetite (Fe3O4) and zerovalent silver (Ag0) nanoparticles were investigated. The aggregation behaviors of the nanomaterials in...
