The potential for contamination of water distribution
systems is a growing public health concern. To
mitigate potential contamination events, accurate prediction
of solute transport through water distribution
pipe networks is crucial. However, most models of flow
and transport through pipe networks assume contaminants
mix instantaneously and completely at pipe junctions.
In many cases, this leads to a poor representation
of the actual mixing behavior, consequently leading to
potentially inaccurate contaminant source detection
and vulnerability and risk assessments.
This article presents data comparisons and new
models for mixing in several different junction configurations:
a new bulk-advective mixing (BAM) model;
EPANET-BAM, an augmented version of the widely
used U.S. Environmental Protection Agency EPANET
software; and, an even newer BAM-WRAP model, not
yet implemented in EPANET-BAM. These new models
provide more accurate assessments of solute/contaminant
concentrations throughout the water distribution
network, which will be useful for risk and exposure
assessments to protect public health. Includes 15 references, tables, figures.
