Adverse Outcome Pathways to Support the Assessment of Chemical Mixtures (BOOK CHAPTER)
Due to the ever-increasing number of chemicals coming to market, and the cost of performing traditional in vivo studies, there has been a shift towards the use of less costly alternative techniques. The adverse outcome pathway (AOP) concept has emerged as a scaffold for organisin...
Watershed-Scale approach to Understanding Fecal Source Input in an Estuarine Watershed (PRESENTATION)
Tillamook Bay, a National Estuary Program site, is one of Oregon’s leading producers of shellfish for human consumption. However, high levels of fecal indicator bacteria that exceed state water quality standards often result in shellfish harvesting area closures leading to...
Spying on benthic communities: Using sediment profile imaging (SPI) to evaluate soft-bottom habitats (PRESENTATION)
Sediment profile imaging (SPI) offers an in situ view of the sediment–water interface and subsurface features in sediments, yielding both quantitative and qualitative data on the biological, chemical, and physical character of the sediments. Since the development of the SP...
USA-scale patterns in wetland water quality as determined from the 2011 National Wetland Condition Assessment (JOURNAL)
Water quality data are a central to ecological condition assessments of lakes, streams, and coastal waters but are less often obtained in wetlands. The 2011 National Wetland Condition Assessment, which spanned natural wetlands across the conterminous USA, provided an unprecedente...
Effect of pH, Dissolved Inorganic Carbon and Orthophosphates on the Nature of Lead Particles and Associated Solubility in Water (PRESENTATION)
Lead exposure impacts the brain, kidneys, and cardiovascular system. Lead found in the blood can be correlated with the concentration of lead in drinking water. Orthophosphate is used to reduce lead at the consumer’s tap by forming relatively insoluble divalent lead orthoph...
Diagnostic Sampling Tools for Lead in Drinking Water (PRESENTATION)
This presentation will focus on practical details for how do conduct "profile" or "sequential" sampling for residences or buildings (such as schools or hospitals), and will critically discuss why most estimates of "exposure" from lead in drinking wat...
Watershed Management Optimization Support Tool (WMOST) Fact Sheet (COMMUNICATION PRODUCT)
WMOST is a software application designed to facilitate integrated water resources management across wet and dry climate regions. The tool allows water resources managers and planners to screen a wide range of practices, such as meeting projected water demand, maintaining minimum ...
Facilitating the valuation of aquatic ecosystem services: tool integration and multimetric indicators of water quality. (PRESENTATION)
The EPA is developing an integrated assessment approach that combines water quality modeling with valuation, to be widely available. In the valuation model, we consider replacing our single water quality index with two, one for human-based recreation and one for aquatic health, a...
Microbial Source Tracking (MST) with qPCR: Technology Transfer and Research (PRESENTATION)
Fecal pollution is the number one biological contaminant in U.S. surface waters with polluted sites in every state. When present, fecal waste can pose a serious public health risk and can lead to severe economic burdens, especially in communities that rely on clean and safe wate...
WMOST v3 (PRESENTATION)
Session 1: Generating initial hydrology and water quality time series using HAWQS (SWAT). Session 2: Using pre-processor with SWAT or HSPF model outputs to create WMOST input files and using SWMM to generate time series for WMOST. Session 3: Problem definition and the WMOST conce...
Detecting microplastics in marine sediments - a methods comparison of isolation and extraction procedures (PRESENTATION)
Despite frequent field observations of microplastics (i.e., plastic particles <5mm in size) there is a critical knowledge gap of their fate and effects in marine and estuarine environments. Many microplastics ultimately accumulate in marine sediments because of physicochemical...
Towards open accounting of water services in Chicago: following the water and the money (PRESENTATION)
Public water utilities provide a range of vital services—drinking water supply, wastewater treatment, stormwater management— to users. Users view these services from diverse perspectives: as rate-payers, workers, elected officials and others. The collective actions ...
Benefits of Solar Energy for Small Rural Water Systems in Puerto Rico (PRESENTATION)
EPA conducted a research demonstration project that looked at the efficacy of sustainable solar-powered water delivery and monitoring systems. A solar-powered water pump and water lines were installed to combine two remote water sources for treatment and distribution to one comm...
CyAN App User's Guide: Android Application Manual (PUBLISHED REPORT)
Cyanobacterial harmful algal blooms (cyanoHAB) cause human and ecological health problems in lakes worldwide. The Cyanobacteria Assessment Network (CyAN) mobile device application (app) uses data from the European Space Agency Copernicus Sentinel-3 satellite Ocean and LandColour ...
Increasing Chloride in Rivers of the Conterminous U.S. and Linkages to Potential Corrosivity and Lead Action Level Exceedances in Drinking Water (JOURNAL)
Corrosion in water-distribution systems is a costly problem and controlling corrosion is a primary focus of efforts to reduce lead (Pb) and copper (Cu) in tap water. High chloride concentrations can increase the tendency of water to cause corrosion in distribution systems. The ...
Per-and Polyfluoroalkyl Substances (PFAS): Source/Site Characterization and Treatment/Remediation.. (PRESENTATION)
The current state of the science regarding per- and polyfluoroalkyl substances (PFAS) analytical methods, sources and fate are provided in this presentation. Analytical methods are critical to properly characterize the temporal and spatial extent of sources of PFAS to the environ...
Preliminary results from the 2018 Niagara River National Coastal Condition Assessment pilot survey (PRESENTATION)
The first system-wide probabilistic survey of ecological conditions the Niagara River was completed during summer of 2018 as part of a pilot study to incorporate Great Lakes connecting channels (GLCC) into the National Costal Condition Assessment (NCCA). The Niagara River is par...
Understanding the drivers of Lake Ontario nearshore nuisance algae blooms: Can models get us any closer? (PRESENTATION)
As part of the 2018 CSMI, several sampling and research studies were undertaken to address ecological concerns in Lake Ontario. One such concern is persistent nuisance algae in the nearshore. Phosphorus is an important driver of algae growth such as for Cladophora, although the...
Variability in physical and biological exchange between coastal wetlands and adjacent Great Lakes (PRESENTATION)
Hydrology is a major governor of physically-driven exchange among coastal wetlands and the adjacent Great Lake, whereas fish movement is a major governor of biologically-driven exchange. We examine variability in the nature and strength of these exchanges using data from 10 Lake...
Releasing Scientific Software in GitHub: A Case Study on SWMM2PEST (PRESENTATION)
