Full Description

The potential for contamination of water distributionsystems is a growing public health concern. Tomitigate potential contamination events, accurate predictionof solute transport through water distributionpipe networks is crucial. However, most models of flowand transport through pipe networks assume contaminantsmix instantaneously and completely at pipe junctions.In many cases, this leads to a poor representationof the actual mixing behavior, consequently leading topotentially inaccurate contaminant source detectionand vulnerability and risk assessments.This article presents data comparisons and newmodels for mixing in several different junction configurations: a new bulk-advective mixing (BAM) model;EPANET-BAM, an augmented version of the widelyused U.S. Environmental Protection Agency EPANETsoftware; and, an even newer BAM-WRAP model, notyet implemented in EPANET-BAM. These new modelsprovide more accurate assessments of solute/contaminantconcentrations throughout the water distributionnetwork, which will be useful for risk and exposureassessments to protect public health. Includes 15 references, tables, figures.
