Estimation of the fate of microbial water-quality contaminants in a South-African river.

A one dimensional steady state stream water quality model, assuming first order decay of microbial water quality variables, was employed in an attempt to describe and predict microbial water quality in the chosen catchment Based on the faecal coliform counts the results indicated that the processes of decay and dilution were inadequate to yield water quality which complied with South African and international guidelines for the domestic and recreational use of water. It was also found that a first order decay model can, with fairly limited data allow a manager to investigate different microbial water quality scenarios in a cost-effective manner.171958 bytesapplication/pdfenCopyright: 1995 Pergamon-Elsevier Science LtdWater quality modellingMicrobial water qualityEscherichia coliFecal coliform countsEngineeringArticleHohls, D., Du Plessis, G., Venter, S., Steynberg, M., De Wet, C., Rodda, N., & Kfir, R.
