  1. The effects of supplied water quality on human health in an urban development with limited basic subsistence facilities.

    Article - En anglais

    Domestic unavailability of water supply in South Africa often leads to improper use of supplied or other unsafe sources of water.

    The relationship between water quality, water availability, water accessibility, water use and incidence of diarrhoea due to these factors, was investigated in this study.

    The study was conducted in a large low socio-economic developing urban settlement.

    Reported diarrhoea cases were followed up to establish the water usage pattern of consumers in these particular households.

    Water was generally obtained from supply at public standpipes and stored in various forms of containers in households.

    Microbiological indicators were used to assess possible contamination of the water supply.

    Tests indicated limited instances of faecal and other forms of microbiological contamination in sections of the water-supply network.

    Indications were also found that the network in this area could intermittently be subjected to pollution from unknown sources although incidences were limited and not prolonged.

    Tests on the bulk water supply from the utility to the consumer water network indicated no faecal contamination in the bulk supply.

    In general the supply quality tested indicated no risk to consumers.

    However, the insanitary condition of containers as well as the manner of storing and handling of the containerised water led to contamination of water supplies. (...)
