Microbial water quality in distribution systems is influenced by a variety of parameters, many of
which are associated with biofilm growth. These include: physical parameters such as flow
characteristics, water age, pH, temperature and pipe material; and, chemical constituents like
the nature and concentration of natural organic matter, the type and concentration of
disinfectants, and the presence/absence of corrosion control chemicals. All of these combine to
create an environment that governs the growth and abundance of biofilms in distribution systems.
In addition, there are other sources of bacteria in distribution systems including breaches in the
physical integrity or breakthrough from treatment. This paper presents
an overview of the methods for assessing microbial water quality and the factors associated with
biofilm proliferation such as organic carbon, disinfection, and pipe materials. Includes 43 references.
