The historical approach for microbial protection has been
embodied in the multiple barrier concept, process control
(turbidity, disinfection, etc.) and monitoring. The information for
assessing this approach has been principally based on bacterial
indicators. This paper discusses how the assurance of the microbial safety of water in the
21st century is moving to incorporate data obtained by the direct
detection of pathogens (typically using molecular methods),
targeting pathogens that are hard to treat (viruses and protozoa),
and application of microbial risk assessment techniques that push
even lower the acceptable levels of potable water risk. The paper ends with a short discussion of improvement in treatment barriers. Includes 8 references, figures.
