The present study incorporated the Webler and Brown algorithm into the open source code of EPANET, water distribution modeling software which characterizes water flow throughout a distribution system.
The present study incorporated the Webler and Brown algorithm into the publically available source code of EPANET water distribution modeling software which characterizes water flow throughout a town's entire public distribution system [ 18].

The current analysis used PCE exposure estimates generated with the addition of water distribution modeling software (EPANET 2.0) to test model assumptions, compare exposure distributions to prior methods, and re-examine the risk of breast cancer.
Because historical exposure measurements were unavailable, we estimated PCE exposure during the study period using EPANET water distribution modeling software that was modified to incorporate a leaching and transport model [ 21, 23].
Because historical exposure measurements were unavailable, we estimated the mass of PCE delivered to each subject's residence using EPANET water distribution modeling software that incorporated a leaching and transport model [ 13, 15].
We used GIS software in conjunction with a modification of the open source water distribution modeling software, EPANET, to create a more detailed exposure model that could easily be manipulated for sensitivity analyses and other improvements.
The authors would like to acknowledge the study research staff and graduate students for their assistance in creating the water distribution models, compiling PCE measurement data, and programming to incorporate the PCE leaching algorithm into the EPANET program's source code.
The components of the algorithm included the initial amount of PCE in the liner, the age of the pipe, the leaching rate of PCE from the liner into the water, and estimates of the direction and rate of flow of water derived from EPANET, water distribution modeling software developed by the U.S. EPA (Rossman 1994), which accounts for the pipe configuration and number of users in a water system.
Because we were concerned that these simplifying assumptions might entail exposure misclassifications, we modified the original method by using EPANET, a public domain water distribution system model developed by the U.S. Environmental Protection Agency, to model each town's entire water distribution system and more rigorously assess the pattern of PCE contamination.
