A pilot-scale pipe distribution study was conducted to determine the effect of blending different
source waters on distribution system water quality as a part of AWWARF and Tampa Bay Water
tailored collaboration project. In this study, finished waters from seven different processes were
blended in varying ratios before distributing to eighteen pilot distribution systems (PDS) and
various chemical and biological water quality parameters were monitored for a total of 12
months. This paper addresses copper release under various source water blending based on
equilibrium modeling, surface characterization, and pilot observations. Includes 14 references, tables, figures.
