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 ...
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 ...
Applying Environmental Release Inventories and Indicators to the Evaluation of Chemical Manufacturing Processes in Early Stage Development (JOURNAL)
As manufacturing processes are developed through the early stages of technology readiness, various assessments can be used to evaluate their performance. Performance indicators describe processes by transforming attributes into scores that represent desirable objectives. One type...
Watershed Management Optimization Support Tool (WMOST): Cost-effective integrated water management (PRESENTATION)
The purpose of the workshop is to introduce participants to the concept of integrated water resource management (IWRM) and to train federal, state, tribal, municipal/utility, nongovernmental organizations, and consultants in the use and applications of EPA's Watershed Management ...
Social Acceptance of Alternative Nutrient-Reduction Technologies in Estuaries (PRESENTATION)
Implementation of nutrient-reduction technologies to reduce loading to estuaries requires agreement by local communities to site, permit, fund, install, maintain, and monitor those technologies. This means federal, state, and local decision makers must trust the technologies to e...
Managing Naturally Occurring Ammonia in Ground Water Systems (PRESENTATION)
Effects of Elevated Ammonia Levels in Source Water and Drinking Water • Biological fouling of filters • Wastewater discharge limits • Oxidant/chlorine demand • Difficulty complying with on C∙t requirements • Interferes with As(III) oxidation • Iron/manganese removal (?) ...
Survey of US wastewater for carbapenem-resistant Enterobacteriaceae (JOURNAL)
A survey for the presence of antibiotic-resistant E. coli was undertaken by collecting samples from seven geographically dispersed US wastewater treatment plants (WWTPs). Samples were collected at each WWTP in cool and summer months and cultured using selective media. The resulti...
Draft Genome Sequences of Antibiotic-Resistant Escherichia coli Isolates from U.S. Wastewater Treatment Plants (JOURNAL)
The spread of antibiotic resistance is a major public health concern. We report the draft genome sequences of three Escherichia coli isolates from primary effluent collected from geographically dispersed US wastewater treatment plants (WWTPs). Genomic analysis confirms the pres...
Requirements for Class A, AA, B Sludge Treatment Processes and the Associated Reporting Requirements (PRESENTATION)
The Clean Water Act requires that EPA regulate the residuals that are left after wastewater treatment. These residuals can be treated and land applied, or they can be incinerated or surface disposed. The regulations that govern these parameters are known as the 503 regulations....
Nooksack-Fraser Transboundary Nitrogen Project: Goals, Results & Links to PSNSRP (PRESENTATION)
Spanning the border of U.S. and Canada, the Nooksack-Fraser transboundary area (2639 km2) is home to the communities of Lynden, Washington, and Abbotsford, British Columbia, with a strong base in farming, fisheries and outdoor recreation. Balancing these uses is a key issue in t...
Adsorption and degradation in the removal of nonylphenol from water by cells immobilized on biochar (JOURNAL)
To investigate the role of adsorption by biochar and biodegradation by bacteria in the wastewater treatment system of microorganisms immobilized on biochar, Nonylphenol (NP) removal (adsorption + degradation) rates and degradation rates from water by NP degrading bacteria immobil...
Aligning Scales in Social and Environmental Elements of Urban Green Infrastructure (PRESENTATION)
A common intended function of green infrastructure is management of urban ecosystem water cycles. The shape of land, specifically its hillslopes, within watersheds regulates the movement of water from uplands to streams. Thus, managing water cycling within watersheds requires wor...
Street-level emissions of methane and nitrous oxide from the wastewater collection system in Cincinnati, Ohio (JOURNAL)
Recent studies have indicated that urban streets can be hotspots for emissions of methane (CH4) from leaky natural gas lines, particularly in cities with older natural gas distribution systems. We assessed the source of CH4 emissions from 104 manholes and sewer grates in Cincinna...
Global Distribution of Human-Associated Fecal Genetic Markers in Reference Samples from Six Continents (JOURNAL)
Numerous bacterial genetic markers are available for the molecular detection of human sources of fecal pollution in environmental waters. However, widespread application is hindered by a lack of knowledge regarding geographical stability, limiting implementation to a small number...
USEPA Regional Applied Research Effort (RARE): Evaluating effects of bioactive contaminants related to municipal wastewater discharges on the South Platte and Colorado River watersheds (PRESENTATION)
Previous chemical and biological monitoring on both the South Platte and Colorado Rivers identified several contaminants and bioactivities of interest. In 2018, a USEPA Regionally Applied Research Effort (RARE) was awarded to better characterize the occurrence of both chemical co...
Exposure Pathways to High-Consequence Pathogens in the Wastewater Collection and Treatment Systems (PUBLISHED REPORT)
Report--Provides information and a screening tool to perform an exposure assessment for emerging pathogens in wastewater systems
Rendering hydrologic ecosystem services from urban soils: a combined field and simulation study (PRESENTATION)
The process of urbanization alters soil properties under pervious surfaces (e.g., right-of-way, parks, lawns, vacant land), yet the subsequent effects on hydrologic ecosystem services such as runoff regulation and supporting plant health are not known. Drawing on a unique urban s...
Life Cycle Assessment and Cost Analysis of Anaerobic Co-Digestion of Food Waste at a Medium-Scale Water Resource Recovery Facility - Portland (PRESENTATION)
This study presents results of a life cycle assessment (LCA) and life cycle cost assessment (LCCA) of a case-study wastewater treatment facility (WWTF) in Massachusetts, the Greater Lawrence Sanitary District (GLSD). The GLSD WWTF is a medium-sized facility that treats an average...
Life Cycle Assessment and Cost Analysis of Anaerobic Co-Digestion of Food Waste at a Medium-Scale Water Resource Recovery Facility - Tucson (PRESENTATION)
This study presents results of a life cycle assessment (LCA) and life cycle cost assessment (LCCA) of a case-study wastewater treatment facility (WWTF) in Massachusetts, the Greater Lawrence Sanitary District (GLSD). The GLSD WWTF is a medium-sized facility that treats an average...
Life Cycle Assessment and Cost Analysis of Mixed Wastewater and Graywater Distributed Treatment for Water Reuse in San Francisco (PRESENTATION)
Communities such as San Francisco, CA are promoting decentralized wastewater treatment coupled with on-site, non-potable reuse (NPR) as a strategy for alleviating water scarcity. This research uses life cycle assessment (LCA) and life cycle cost analysis (LCCA) to evaluate severa...
Innovative Biological Treatment Process for the Removal of Ammonia, Arsenic, Iron and Manganese from a Small Drinking Water System in Gilbert, Iowa (Phase 1: Pilot Evaluation) (PUBLISHED REPORT)
Many regions in the United States have excessive levels of ammonia in their drinking water sources (e.g., ground and surface waters) as a result of naturally occurring processes, agricultural and urban runoff, concentrated animal feeding operations, municipal wastewater treatment...
