Abstract:

The aim of the study was to analyses and evaluate the current water pollution caused by asbestos and gold mining and point out the main pollutants and their impacts. The other objective of the study proposed an advanced water purification unit to reduce water pollution load with consideration of specific local conditions and international standards. Data on pollution levels were collected from abandoned asbestos and gold mines. A total of fifty water samples were collected from the gold and asbestos mine dumps. To determine water quality, fifteen drinking water samples were collected from residential areas in the Mashaba mining area. Results of the study indicated that except for manganese, iron, and arsenic the level of Hg, Cu and Zn were within the limits which are set out by SAZS 560:1997. Results from the abandoned gold and asbestos dumps indicate that manganese and iron were very high in asbestos than in gold mines. Copper levels were significantly lower in both asbestos and gold abandoned mines in the study area. The results of the study showed that there were high arsenic and manganese levels and as such the study proposes the adoption of the SORAS, ionization, and reverse osmosis technologies. Based on the findings, the study recommends that there is the adoption of the above-stated technologies such that contaminated water can be used for agricultural purposes and also have little damage to the environment.
