An innovative symbiotic microalgae-IFAS process for nutrient removal and photo-oxygenation: Multi-scale investigations using microelectrodes and next-generation molecular tools (PRESENTATION)
A consortium of algae and bacteria is known to be effective in removing nitrogen (N) and phosphorus (P) from wastewater; however, the concept has largely been limited to suspended processes and fixed filmed (biofilm) processes have not fully been explored. Here we demonstrate the...
Developing Sediment Remediation Goals at Superfund Sites Based on Pore Water for the Protection of Benthic Organisms from Direct Toxicity to Non-ionic Organic Contaminants (PUBLISHED REPORT)
This document contains a methodology for developing interstitial water remediation goals (IWRGs) for nonionic organic pollutants (toxicants) in sediments for the protection of benthic organisms. The document provides the basis for using the final chronic values (FCVs) from EPA’s...
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...
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 ...
Defining the relationship between individuals’ aggregate and maximum source-specific exposures (PRESENTATION)
The concepts of aggregate and source-specific exposures play an important role in chemical risk management. The concepts of aggregate and source-specific exposures play an important role in chemical risk management. Aggregate exposure to a chemical refers to combined exposures fr...

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...
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...
