An assessment of the contribution of agricultural non-point source pollution on the water quality of the Vaal River within the Grootdraai Dam catchmentNcube, Scott 26 January 2015 (has links)
This study assesses the contribution of agricultural non-point source pollution, to poor water
quality of the Vaal River within the Grootdraai dam catchment area. The study evaluates
agricultural pollutants affecting the quality of water within the study area. The impact of
agricultural non-point source pollution on the water quality of the Vaal River was evaluated
by establishing a correlation between the quantity of polluted runoff reaching the River and
the quantity of measured nitrates and phosphates in its waters. A questionnaire using random
sampling was used to capture data from 15 commercial farmers 35 local residents and the
Department of Water Affairs management. The results of the study show that agricultural
nutrients are heavily impacting and compromising the water quality of the Grootdraai Dam.
The mean concentrations of Nitrogen and Phosphorus were found to be well above the water
quality guidelines there by promoting eutrophication. / Environmental Sciences / M. Sc. (Environmental Management)
