Despite years of research, the mechanisms by which
microorganisms survive in distribution systems and how
various water quality parameters affect their survival are
still not fully understood. Several factors affect bacterial
regrowth in drinking water supplies. Although biodegradable
organic materials, the "food" for bacteria, have often been
thought to be a main culprit, this study shows that may not be
the case. By evaluating the biological quality in a full-scale
chloraminated distribution system, this study examined the
various factors that affect bacterial regrowth. The conclusions of
this study are likely to help utility managers gain a better understanding
of the factors controlling bacterial regrowth and help
them make well-informed decisions on treatment process
improvement or distribution system maintenance. For example,
rather than merely reducing the concentration of biodegradable
organic matter, utilities may need to take multiple approaches to
maintain good biological quality or to solve existing problems in
their distribution systems. Includes 34 references, tables, figures.
