Microbial Source Tracking DOEE Briefing (PRESENTATION)
A webinar presented for EPA Region 3 on Microbial source tracking overview.
Water Biosensor Challenge to Address Toxicity of Water (PRESENTATION)
An ongoing concern for water treatment systems and resource managers is the need to monitor for the presence of increasing number of pollutants from agricultural, municipal, and industrial outfalls that are present in U.S. source waters. The associated environmental compounds can...
Impact of Growth Conditions and Suspension Time on Toxin Release from M. aeruginosa Upon Exposure to Potassium Permanganate (PRESENTATION)
The objective of this work was to assess the effects of KMnO4 on pure cultures of cyanobacteria (Microcystis aeruginosa) in a jar test. Of particular interest was the impact this oxidant has on the release of intracellular toxin from cells as a function of growth conditions in cu...
Microbial pathogens in source and treated waters from drinking water treatment plants in the US (PRESENTATION)
An occurrence survey was conducted on selected pathogens in source and treated drinking water collected from 25 drinking water treatment plants (DWTPs) in the United States. Water samples were analyzed for the protozoa Giardia and Cryptosporidium (EPA Method 1623); the fungi Asp...
Addressing Toxicity of Water using the Challenge Process (PRESENTATION)
Exposure concerns from an increasing number of pollutants in US waters requires the need for better monitoring. The pollutants are diverse and can include pesticides, heavy metals, personal care products, natural toxins such as cyanobacterial toxins, and a host of other organic ...
Water Network Tool for Resilience (WNTR) User Manual - (PUBLISHED REPORT)
The Water Network Tool for Resilience (WNTR) is a new Python package designed to simulate and analyze resilience of water distribution networks to a variety of disaster scenarios. WNTR can help water utilities to explore the capacity of their systems to handle disasters and gui...
A Novel Coupling Pattern in Computational Science and Engineering Software (PAPER IN NON-EPA PROCEEDINGS)
Computational science and engineering (CSE) software is written by experts of certain area(s). Due to the specialization,existing CSE software may need to integrate other CSE software systems developed by different groups of experts. Thecoupling problem is one of the challenges f...

Correlation of Traditional Water Quality Parameters with Metal Concentrations in Permeable Pavement Infiltrate (PRESENTATION)
EPA constructed a 4,000-m2 parking lot for research and demonstration of three permeable pavements [permeable interlocking concrete pavers (PICP), pervious concrete (PC), and porous asphalt (PA)] at the Edison Environmental Center in Edison, NJ in 2009. Infiltrate samples from e...
Water System Adaptation to Hydrological Changes: Module 1, Introduction to Water System Adaptation (PRESENTATION)
Contemporary water management requires resilience, the ability to meet ever increasing water needs, and capacity to adapt to abrupt or transient changes in water quality and availability. For this purpose, effective adaptation to extreme hydrological events (e.g. intense storms, ...
Home Plumbing Simulator for the Study of Copper and Lead Corrosion and Release, Disinfectant Demand, Biofilm Activity and General Water Quality (PRESENTATION)
Presentation at the Ohio AWWA meeting, 2017 September.
Hospital visits for gastrointestinal Illness after a major water main break in 2010 (PRESENTATION)
Background/Aim Water main breaks can occur due to the stresses of an aging infrastructure and changing climate. Water main breaks are a public health concern because they can cause pressure transients (specifically, abrupt decreases in water pressure/flow in the pipeline), which ...
Nutrient Removal and Resource Recovery: Effect on Life Cycle Cost and Environmental Impacts of Small Scale Wastewater Treatment (PRESENTATION)
Many communities across the U.S. are required to upgrade wastewater treatment plants (WWTP) to meet increasingly stringent nutrient effluent standards. However, increased capital, energy and chemical requirements of upgrades create potential trade-offs between eutrophication pote...

Journal article
Tillamook Estuary Case Study: Local Drivers Influencing Coastal Acidification (PRESENTATION)
US EPA initiated a study in the Tillamook estuary and watershed focused on the impact of changes in watershed land use, ocean conditions, and weather on estuarine water quality and ecosystem goods and services production within the estuary. This project is a collaboration betwee...
Land Use. (BOOK CHAPTER)
Land use in the Narragansett Bay Watershed (NBW) is subject to conversion, and these changes influence the Watershed’s hydrologic functions. Changes of natural habitat such as wetlands and forests to urban lands have impacted how water is delivered to rivers and lakes, to g...
Population (BOOK CHAPTER)
Population growth influences many stressors on Narragansett Bay and its Watershed, including all landscape and chemical stressors discussed in other chapters of this report. In numerous ways, population growth affects the condition of the Bay ecosystem, Watershed ecosystem, and h...
