In 2003 and 2004, Water System Master Plans were completed for the cities of Glendale,
Arizona and Mesa, Arizona. Extended period simulation (EPS) water age and source trace analyses were conducted and used in
conjunction with treated water quality curves of disinfection byproduct (DBP) formation
potential to evaluate the water quality impacts of various alternative improvements. This
paper presents the methods and results of detailed evaluations of distribution system
water quality as conducted for these two systems.
Both Glendale and Mesa receive treated water from two water treatment plants, with each
plant having different DBP formation potential. In addition, treated water from the plants
is supplemented by direct input of groundwater from wells located throughout the
distribution system. In addition to water age analyses, source tracing analyses were
required to evaluate the source of treated water throughout the distribution system.
Effective presentation of the modeling results, in a manner that can be interpreted and
readily understood, allows for effective quality control review and increased confidence
in the resulting recommendations. This paper presents details on the presentation of
the results of the EPS water age and source tracing analyses for Glendale and Mesa. Includes table, figures.
