  • Use of Microbial Source Tracking Tools in Waterborne Disease Outbreak Response (June 27, 2018)

    This was a joint webinar with the Centers for Disease Control and Prevention (CDC)

    Fecal pollution in recreational and drinking source waters can result in outbreaks leading to the transmission of disease. Information on the sources of fecal pollution is important because the level of human health risk can change from one pollution source to another. Understanding the source of disease causing enteric pathogens (e.g., norovirus) in outbreak environments is vital for determining and prioritizing remediation strategies. General fecal indicators, such as E. coli and enterococci, are typically used to assess fecal pollution; however, these methodologies do not discriminate between pollution sources. Recent advancements in the field of molecular biology have led to the development of microbial source tracking (MST) tools that can characterize fecal pollution from different animal groups.

    The Centers for Disease Control and Prevention (CDC) is utilizing MST tools developed by U.S. Environmental Protection Agency (EPA) scientists for environmental investigations of waterborne outbreaks. For this webinar, Dr. Orin Shanks (EPA) provided an overview on EPA's MST method development activities, and Dr. Mia Mattioli (CDC) highlighted a CDC response to a recent waterborne outbreak where an EPA developed human-associated MST procedure was employed to help confirm a source of norovirus. This case scenario demonstrated how EPA and CDC interagency collaborations provide invaluable assistance to state environmental investigations of waterborne outbreaks.

  • Tools for Assessing Lakes and Streams: Lake-Catchment (LakeCat) and Stream-Catchment (StreamCat) Datasets (May 30, 2018)
    StreamCat and LakeCat Map

    Freshwater ecosystems reflect, in part, the characteristics of watersheds that feed them. It is critical to understand the natural and human-related features of watersheds to effectively manage and conserve their associated streams or lakes. However, the generation of watershed boundaries and the derivation of watershed information is a time-consuming process that requires specialized expertise. To facilitate the acquisition of these types of information, EPA developed the Stream-Catchment (StreamCat) and Lake-Catchment (LakeCat) Datasets. These tools are extensive collections of landscape metrics for about 2.6 million stream segments, and 378 thousand lakes and their associated catchments within the conterminous United States; both include natural and human-related landscape features. The data are summarized for both individual stream-segment and lake local catchments, and for cumulative upslope watersheds. StreamCat and LakeCat were developed to support the National Rivers and Streams Assessment and the National Lakes Assessment, and will be useful to states conducting similar assessments for lotic and lentic waters, respectively. Both tools are available to the public for download and provide an important resource for understanding and characterizing the Nation’s freshwaters.

    This presentation will introduce the generation, structure, and types of data that are available from StreamCat and LakeCat. In addition, we will provide examples of how these data have been used by the US EPA to model instream and in-lake conditions, including the probable biological condition of 1.1 million stream segments and the probability of lake eutrophication (chlorophyll a > 7µg/L) at 297 thousand lakes.

  • Village Blue Project: Real-Time Water Quality Monitoring in the Baltimore Harbor (February 28, 2018)

    Webinar recording coming soon.
    Village Blue sensors on the Jones Falls River

    EPA and the U.S. Geological Survey (USGS) initiated the Village Blue project to increase public awareness about local water quality in the Baltimore Harbor and the Chesapeake Bay. Village Blue is a demonstration project providing real-time sensor-based water quality monitoring data to the Baltimore community and complements work already being done toward the Waterfront Partnership of Baltimore's goal of making Baltimore Harbor swimmable and fishable by 2020.

    The water quality monitoring data are displayed on EPA’s Village Blue monitoring application, which shows the data in a mobile- friendly, easy-to-understand format.  Several local and state organizations have partnered with EPA and USGS to use the Village Blue demonstration project to help raise public awareness of water quality in the Baltimore Inner Harbor. Village Blue’s monitoring data will help close water quality information gaps and give citizens and professional scientists more data to inform communities, policies, and environmental restoration efforts.

    This webinar presented the Village Blue research project and demonstrated how to access the application and explore the real-time water quality data.

  • National Stormwater Calculator for Managing Runoff Using Green Infrastructure: Addition of a Cost Module and a Mobile Web Application Version (January 31, 2018)

    Image of a screenshot of the mobile web application and desktop versions of the SWC.

    Stormwater discharges continue to cause impairment of our Nation’s waterbodies. Conventional stormwater infrastructure, or gray infrastructure, is largely designed to move stormwater away from urban areas through pipes and conduit. Runoff from these surfaces can overwhelm sewer systems and end up contaminating local waterways. When stormwater runs off impervious streets, parking lots, sidewalks, and rooftops, it can carry pollutants to streams, rivers, and lakes. Runoff flows can also cause erosion and flooding that can damage property, infrastructure, and wildlife habitat. In addition to runoff problems, impervious surfaces also prevent water from penetrating the soil and recharging groundwater supplies.

    Green infrastructure, such as rain gardens, and porous pavement, is becoming an increasingly attractive way to reduce the amount of stormwater runoff that flows into wastewater treatment plants or into waterbodies untreated, and to recharge aquifers. It provides many environmental, social, and economic benefits that promote urban livability, such as improved surface water quality, water conservation, and improved aesthetic and property value. EPA researchers have been studying green infrastructure practices and developing models and tools to help communities manage their stormwater runoff and address nutrient impairment.

    EPA developed the National Stormwater Calculator (SWC) to help support local, state, and national stormwater management objectives and regulatory efforts to reduce runoff through infiltration and retention using green infrastructure practices as low impact development controls. It is designed to be used by anyone interested in reducing runoff from a property, including site developers, landscape architects, urban planners, and homeowners. It can be used for any location within the United States, including Puerto Rico. This webinar provided potential and example applications, and presented the new cost module and mobile web application version that can be used on desktops and on mobile devices, such as smartphones and tablets.

2017 Webinars

  • Integrated Decision Support Tool (i-DST) for Life Cycle Cost Assessment of Grey and Green Stormwater Management Infrastructure (October 25, 2017)

    Green infrastructure practices for urban stormwater managementPlanning stormwater infrastructure is difficult because proposed projects often have multiple objectives, including managing hydrology and water quality, providing communities with co-benefits, and minimizing life cycle costs that account for operation and maintenance. Traditional grey infrastructure and more natural green infrastructure are two distinct pathways of meeting these diverse objectives. Grey infrastructure typically involves greater capital investments, while green infrastructure may have more annual costs per volume of water managed. Green infrastructure can also provide societal co-benefits, such as additional urban green spaces, and improved water and air quality and public wellness. This makes deciding between implementation of grey, green, or hybrid (combination of grey and green) approaches challenging.

    This presentation highlighted National Priorities grantee work on the development of a planning-level, integrated decision support tool, i-DST, which contains modules that simulate continuous runoff and water quality, using historical climate data and under different climate scenarios. The developed i-DST will also use a multiple-criteria decision analysis to optimize stormwater infrastructure based on user-defined institutional barriers, and economic, environmental, and societal objectives. Central to the estimation of economic costs is the valuation of operation and maintenance costs. An overview of the synthesis of regional green infrastructure cost and performance parameters that allow for application of the tool across the different climatic regions of the United States was also provided.

  • Land Use, Environmental Stressors, and Water Resources:  Degradation to Restoration (August 30, 2017)

    Mansonry DamLand 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 availability of freshwater will be impacted on local to global scales. Global water security must consider the interaction between land use, environmental stressors, and global water demand.

    Using representative studies from around the world, plus our own body of research in human-dominated ecosystems, environmental stressors and management practices impacting global water quantity and quality were discussed. A conceptual framework for understanding and predicting global patterns of water use and water quality degradation, characterized by the increasing interaction between land use and environmental stressors was then discussed. Finally, the role of ecosystem restoration and management in securing and improving water resources and related ecosystem services was presented.

  • Nonpotable Water Reuse in Urban Environments (June 21, 2017)
    Water reuse water cycle from source to use.

    Introduction (Presented by Dr. Matthew Small, EPA's Region 9). Prior to the presentations, a regional perspective on the collaborative efforts between EPA and City of San Francisco will be provided.

    Presentation 1—San Francisco’s Nonpotable Water Program (Presented by Paula Kehoe, San Francisco Public Utilities Commission). Onsite reuse is one solution to help communities diversify water supplies as traditional supplies face challenges from issues such as drought and flooding. In 2012, the San Francisco Public Utilities Commission (SFPUC) launched their Nonpotable Water Program, which streamlined the regulatory process for buildings to install onsite nonpotable water systems to produce nonpotable water for toilet flushing and irrigation. Since 2014, SFPUC has been leading a national effort, in partnership with public health regulators, water and wastewater utilities, and research foundations, to address appropriate public health standards and consistent regulatory approaches for onsite water nonpotable systems.

    Presentation 2EPA's Research to Support Decentralized Nonpotable Water Systems (Presented by Dr. Jay Garland, EPA's Office of Research and Development). As the reuse of alternative water sources continues to gain popularity, public utilities and other stakeholders are seeking guidance on pathogen treatment requirements and monitoring approaches for nonpotable use of onsite collected water (e.g., combined wastewater, graywater, stormwater, and roof runoff). This talk presented risk-based pathogen log reduction requirements for various types of onsite collected wastewaters used for a range of nonpotable uses. In addition, approaches for monitoring treatment performance for pathogen were discussed, emphasizing the limitation of traditional fecal indicators and the potential use of more commonly occurring and abundant microorganisms as process indicators.

    4. Yesterday’s Demand, Tomorrow’s Water Systems: Adjusting to NormalsAs water fixtures, appliances, and water-use practices have become more efficient, aggregate and per-capita usage has declined. Systems serving legacy cities have seen further declines in the wake of lost economic activity and populations. Due to these and other factors, existing water utility and premise plumbing systems may be oversized relative to needs and pose potential health risks associated with stagnant water. Dr. Beecher eviewed the planned approach to analyzing and summarizing these trends for the purposes of this study.

    5. Water Microbiology Associated with Plumbing and Health RisksWater conservation can lead to low flows and increased water age in distribution systems and premise plumbing. The reduced chlorine residual over time can subsequently allow for microbial growth in drinking water and biofilms along the piping materials. Additionally, organic carbon from certain types of pipes may provide nutrients for increased growth. Dr. Mitchell reviewed how the synergy among these events contribute to microbial risks, especially those produced by opportunistic pathogens.

  • Rapid Benefit Indicators Approach: A Process for Assessing the Social Benefits of Ecological Restoration (February 22, 2017)
    All photos by Rick McKinney Image 1 is of the Woonasquatucket River, image 2 is a person kayaking down the Woonasquatucket River, image 3 is the Woonasquatucket River.

    Ecological restoration can reestablish ecosystem services that provide important social benefits. Also, managers with limited funds and resources often need to prioritize potential restoration sites for implementation. Prioritizing restoration sites based on ecological functioning and expected ecosystem services production alone neglects vital information for evaluating tradeoffs—for example, determining who benefits from the resulting ecosystem services and by how much. The EPA developed Rapid Benefit Indicators (RBI) approach is an easy-to-use process for assessing restoration sites using non-monetary benefit indicators. The RBI approach uses readily-available data to estimate and quantify benefits to people around an ecological restoration site using ecosystem service benefit indicators based on economic principles. The framework uses five questions to guide the process of indicator selection and measurement:

    1. Can people benefit from an ecosystem service?
    2. How many people benefit?
    3. How much are people likely to benefit?

  • Systems View of Nutrient Management: Nutrient Recovery from Human Urine (December 14, 2016)

    Urine is the primary source of phosphorus and nitrogen in municipal wastewater. Accordingly, it is important to consider for nutrient management. This webinar covered new science on recovering nutrients from human urine. This included issues of source separation in buildings, use at the farm, review of health issues, and factors influencing the environmental sustainability of nutrient management strategies. This webinar is an output of preliminary scientific research and demonstrations achieved from the Centers for Water Research on National Priorities Related to a Systems View of Nutrient Management, which were funded by EPA's Science to Achieve Results (STAR) grants.

    Agenda and Presenters

    2. BuildingWaterless urinals can serve a two-fold benefit of water conservation and implementation of urine source separation system. However, due to urine’s composition and the presence of the urease enzyme that hydrolyzes urea, valuable nutrients readily precipitate in the urinal fixtures and pipes. This hinders both water conservation and nutrient recovery efforts because of maintenance problems. This presentation reviewed controlled laboratory experiments and a demonstration study that increases our understanding of the urea hydrolysis process in waterless urinals by mimicking and inhibiting urea hydrolysis so as to benefit water conservation and nutrient recovery.

  • Toolkit of Available EPA Green Infrastructure Modeling Software (October 26, 2016)

    Stormwater discharges continue to cause impairment of our Nation’s waterbodies. Conventional stormwater infrastructure, or gray infrastructure, is largely designed to move stormwater away from urban areas through pipes and conduit. Runoff from these surfaces can overwhelm sewer systems and end up contaminating local waterways. When stormwater runs off impervious streets, parking lots, sidewalks, and rooftops, it carries pollutants, such as motor oil, lawn chemicals, sediments, and pet waste to streams, rivers, and lakes. Runoff flows can also cause erosion and flooding that can damage property, infrastructure, and wildlife habitat. In addition to runoff problems, impervious surfaces also prevent water from penetrating the soil and recharging groundwater supplies.

    The names of five of EPA's green infrastructure models and tools written inside of rain drops: GiWIZ, WMOST, VELMA, SWMM, SWC.

    Green infrastructure (e.g., rain gardens, green roofs, porous pavement, cisterns) is becoming an increasingly attractive way to reduce the amount of stormwater runoff that flows into wastewater treatment plants or into waterbodies untreated, and to recharge aquifers. It provides many environmental, social, and economic benefits that promote urban livability, such as improved surface water quality, water conservation, and improved aesthetic and property value. Green infrastructure is also incorporated into municipal separate storm sewer system (MS4) and National Pollutant Discharge Elimination System (NPDES) stormwater permits for retention requirements for various states across the Nation. EPA researchers in the Office of Research and Development (ORD) have been studying green infrastructure practices and developing models and tools to help communities manage their stormwater runoff and address nutrient impairment. This webinar presented a toolkit consisting of five EPA green infrastructure models and tools, along with communication material, that can be used as a teaching tool and as a quick reference resource for use by planners and developers when making green infrastructure implementation decisions, and can also be used for low impact development design competitions. The models and tools included are the Green Infrastructure Wizard (GIWiz), Watershed Management Optimization Support Tool (WMOST), the Visualizing Ecosystem Land Management Assessments (VELMA) Model, the Storm Water Management Model (SWMM), and the National Stormwater Calculator (SWC).

  • Valuing Ecosystem Services Generated by Nutrient Reductions - A Spatial Approach (August 31, 2016)
    stream flowing over rocks

    Agricultural Best Management Practices (BMPs) aimed at reducing nutrient and sediment loads play an important role in meeting goals to restore ecosystem function in the Chesapeake Bay. However, those BMPs also affect water quality in contributing rivers. As part of the Penn State Center for Nutrient Solutions, we have developed a spatial model of ecosystem services generated by the water quality improvements in rivers and streams contributing to the Chesapeake Bay that result from BMPs applied to agricultural lands. This model accounts for where the BMPs are situated, the impact they have on the immediate watershed, and the impact reduced loadings have on downstream rivers and the Chesapeake Bay. The model also accounts for where people are located relative to the improved water bodies, and the resulting ecosystem services they enjoy. The model can serve as a prototype for a BENMAP-type tool applied to surface water.

  • Contaminants of Emerging Concern (CECs) in Source and Treated Drinking Water (June 29, 2016)

    Contaminants of emerging concern (CECs) is a term which encompasses a vast array of chemicals such as pharmaceuticals, perfluoroalkyl substances, and surfactants, as well as microorganisms such as Mycobacteria and Legionella. These contaminants end up entering the water cycle, either through municipal or household use (entering the grey water), or excretion (entering the black water). CECs can survive wastewater treatment, and end up in surface waters, along with other contaminants which may run off of the land into the watershed. This water can be the drinking water source for a downstream community. Scientists from EPA and the U.S. Geological Survey have collaborated on a study examining the occurrence of CECs both in source water and treated drinking water from drinking water treatment plants from across the United States. This presentation discussed the occurrences of the chemical and microbial contaminants measured in the study, and examined the implications for aquatic life and human health.

  • Assessment of Major Ion Effects on Aquatic Organisms (April 27, 2016)
    EPA aquatic effects research

    Natural geochemical weathering introduces several inorganic ions to natural waters, primarily Na+, K+, Ca2+, Mg2+, Cl-, SO42-, and HCO3-/CO32-. These ions not only define the basic chemistry of surface waters, but they also have physiological roles and are actively regulated by aquatic organisms. However, several land uses, including energy and mineral extraction, can increase concentrations of these geochemical ions to concentrations that pose ecological risks, either through direct discharge of process or waste waters, of by accelerating geochemical weathering. The ecological effects of increased ion concentrations are being explored through several inter-related research efforts that span levels of biological organization from physiological through field community levels. Research to date demonstrates that these effects are dependent on both the specific ions that are elevated, and on the background composition of the receiving water. This webinar provided an overview of EPA’s research in this area, and some of the implications for predicting ecological risks and informing management decisions.
