  1. Waterborne diseases : Update on water quality assessment and control.

    Article - En anglais

    Water-borne diseases are the most important concern about the quality of water.

    The pathogens involved include a wide variety of viruses, bacteria and protozoan parasites.

    Due to differences in size, structure, composition and excretion by humans and animals, their incidence and behaviour in water environments differ.

    This constitutes difficult challenges for testing the safety of water and the efficiency of treatment processes.

    Further complications are that many water-borne pathogens, notably the great majority of viruses as well as protozoan cysts and oocysts, are not readily detectable.

    In addition, the prevalence of various water-borne pathogens changes as selective pressures change.

    In view of the diverse and variable goalposts, new epidemiological data, and progress in technology and expertise, the methods and strategies for quality monitoring and control of water-borne diseases are continually being revised and updated.

    This paper reviews the latest approaches to water quality monitoring using indicators of human and animal faecal pollution, and new methods for the detection of viruses.

    The importance of simple, economic and rapid methods for high frequency basic monitoring of water quality and the efficiency of treatment systems is emphasised Reference is made to the fundamental need for microbiological quality data in the management of national and regional water resources and supplies.
