Document Type: Monograph
This report describes a national survey completed with sampling of the rivers and borehole sources. Full quality assurance of the analysis has been completed and parallel epidemiological studies have proceeded under the direction of CDSC with funding from DoE. The period has again shown low levels of oocysts in the river sources and no positive results in the boreholes. No second stage investigations have therefore been carried out on the river sites to identify the sources of oocysts. Overall in the survey oocysts have been low or absent in all sources. No outbreaks of cryptosporidiosis have been detected in the areas served by the sources surveyed as shown by the questionnaire returns to CDSC. The final report on the survey will be prepared with more detailed examination of the positive results.
