This book is proposed because it offers a comprehensive coverage of
most of the topics pertaining to drinking water microbiology. It
concerns the public health aspects of drinking water treatment and
distribution and describes the different water treatment processes
(pretreatment, coagulation, flocculation, sedimentation,
filtration, disinfection) and their impact on waterborne microbial
pathogens and parasites. The quality of the treated water may
however be degraded in the water distribution system (WDS).
Microorganisms attach to surfaces, namely water distribution pipes,
and form biofilms which allow their survival and growth, gene
exchange and resistance to disinfection. The biofilm environment
also allows the survival and potential growth of primary and
opportunistic pathogens. The water distribution system may also
harbor various organisms (e.g., algae, cyanobacteria, fungi,
actinomycetes, free living amoebas, invertebrates, iron and
manganese bacteria, nitrifying bacteria) which alter the quality of
treated water. The biostability of the treated water is an
important factor to consider if one wants to reduce bacterial
growth in WDS. Various approaches/methodologies have been proposed
to assess the bacterial growth potential in WDS. Due to
bioterrorism threats to drinking water safety, one needs to know
about the scope of this threat, the microbial agents involved and
the safeguards that are put in place to protect this precious
resource. The proposed book would not be complete if one fails to
discuss the research on drinking water quality in developing
countries which experience more the two million deaths resulting
from diarrheal diseases. Various simple and low-cost treatment
technologies are available for improving the quality of drinking
water in developing countries. Finally, due a surge in bottled
water sales around the world, there is a great need to know about
the microbiological water quality of this resource which is often
misunderstood by the public at large.
