Water quality complaints related to particulate matter and discolored water can be
troublesome for water utilities in terms of follow-up investigations and implementation of appropriate
actions because particulate matter can enter from a variety of sources; moreover, physicochemical
processes can affect the water quality during the purification and transportation processes. The origin
of particulates can be attributed to sources such as background organic/inorganic materials from
water sources, water treatment plants, water distribution pipelines that have deteriorated, and
rehabilitation activities in the water distribution systems. In this study, a practical method is proposed
for tracing particulate sources. The method entails collecting information related to hydraulic, water
quality, and structural conditions, employing a network flow-path model, and establishing a database
of physicochemical properties for tubercles and slimes. The proposed method was implemented
within two city water distribution systems that were located in Korea. These applications were
conducted to demonstrate the practical applicability of the method for providing solutions to customer
complaints. The results of the field studies indicated that the proposed method would be feasible for
investigating the sources of particulates and for preparing appropriate action plans for complaints
related to particulate matter.
