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...
Developing Sediment Remediation Goals at Superfund Sites Based on Pore Water for the Protection of Benthic Organisms from Direct Toxicity to Non-ionic 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...
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...
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.
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...
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, ...
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...
Multi-media assessment of lead for USA children with SHEDS-multimedia (PRESENTATION)
This effort stemmed out of OW’s request to ORD to provide technical assistance for revising the LCR
Quantitative Microbial Risk Assessment Tutorial - Primer (PUBLISHED REPORT)
This document provides a Quantitative Microbial Risk Assessment (QMRA) primer that organizes QMRA tutorials. The tutorials describe functionality of a QMRA infrastructure, guide the user through software use and assessment options, provide step-by-step instructions for implementi...
