M.Sc. (Botany) / Eight sampling points were selected on the Jukskei River so that the impact of inflows from various localities on the quality of the river water could be determined. Samples were taken every two weeks from the 4th April 1983 to 19th March 1984. The temperature, conductivity, dissolved oxygen and pH of the water were determined on site. Determinations of total phosphorus (as p-po1-), nitrate (NO), chloride (C11 and chlorophyll a were done. After filtration the water of each sample was inoculated with Euglena gracilis and incubated for four days under controlled conditions after which the Euglena chlorophyll-content, primary productivity and biological growth potential were measured...
