Development of effective dispersion coefficients for premise plumbing systems
(PRESENTATION) [Presented : Apr 19, 2023]
Improve concentration modeling within premise plumbing systems to understand fate and transport/ Also related to improved premise plumbing model.
EPANET-MSX 2.0
(DATA/SOFTWARE) [Published : Jul 12, 2023]
Upgrade of the tool to work with EPANET2.2
EPANET-MSX 2.0 User Manual
(PUBLISHED REPORT) [Published : Jul 01, 2023]
EPANET-MSX enables the advanced water quality modeling of reactions that involve multiple reacting species. It will help researchers and practitioners better understand and analyze the water quality problems within drinking water distribution system. This manual documents the met...
Modeling Nicotine Induced Chlorine Loss with EPANET-MSX
(PRESENTATION) [Presented : May 24, 2023]
Many reactions that occur in water distribution systems cannot be completely described by the single species reactions available within EPANET, such as disinfectant byproduct (DBP) formation and associated disinfectant loss. To address this limitation, EPANET-MSX (Multi Species e...
Modeling Nicotine-Induced Chlorine Loss in Drinking Water Using Updated EPANET-MSX
(JOURNAL) [Published : Dec 01, 2023]
This study illustrates the usage of multi-species modeling tool to analyze water quality and evaluate water safety within drinking water distribution system.
US EPA's Water Quality Modeling Tools and Sensor Research
(PRESENTATION) [Presented : Sep 29, 2023]
This presentation provides a general overview of EPA's modeling tools and associated water quality sensor research. Tool functionality is described and how they interact or are informed by sensor research will be discussed during the presentation. Tools include EPANET, EPANET-MSX...

EPANET Multispecies Extension to Model Advection-Dispersion-Reaction within Water Distribution System
(PRESENTATION) [Presented : Jun 08, 2022]
EPANET has been used widely to model hydraulics and water quality changes within drinking water distribution systems. One limitation of the EPANET water quality analysis was that it tracks the transport of only one soluble substance. A decade ago, EPA released an extension of EPA...

Modeling Drinking Water Lead Exposure from Premise Plumbing
(PRESENTATION) [Presented : Jun 05, 2018]
Exposure to drinking water contaminants, specifically lead, remains an important health concern. Modeling lead release within home plumbing systems includes quantifying the dissolution of lead into the water from all lead sources, and the transport of that lead through the pipes/...

Cometabolism of Monochloramine by Distribution System Relevant Mixed Culture Nitrifiers
(PRESENTATION) [Presented : Nov 18, 2014]
Monochloramine (NH2Cl) is increasingly used as a residual disinfectant. A major problem related to NH2Cl is nitrification in distribution systems, leading to rapid NH2Cl residual loss. Ammonia-oxidizing bacteria (AOB), which oxidize ammonia (NH3) to nitrite, can cometabolize chem...
Monochloramine Cometabolism by Ammonia-Oxidizing Bacteria. Report #4341
(EXTRAMURAL DOCUMENT) [Published : Oct 01, 2014]
Chloramine use is widespread in United States (US) drinking water distribution systems as a secondary disinfectant. In a recent survey of water utilities, 30% of the respondents used chloramines to maintain distribution system residual (AWWA Water Quality and Technology Division...
