“…The maximum value reported in Figure 3 refers to a rural area characterized by the presence of mining activities [29]. With regard to polycyclic aromatic hydrocarbons (PAHs), [33,50] report that they are associated with the presence of industrial activities in rural and peri-urban areas; improper waste disposal in the facility area, which could cause the release of organic chemicals, including PAHs; and fumes from fossil fuel combustion being deposited back on the land. As to pollutants in MZ surface water ( Figure 4), it was found that based on the modest number of collected data (176 data), concentrations are generally lower than the corresponding ones found in South African rivers.…”

According to a recent report by the World Health Organization (WHO), the countries which still have limited access to water for drinking purposes are mainly those in the Sub-Saharan region. In this context, the current study provides an overview of the quality of surface water and groundwater in rural and peri-urban areas of the Republic of South Africa (RSA) and Mozambique (MZ) in terms of concentrations of conventional pollutants, inorganic chemicals, microorganisms, and micropollutants. Their values were compared with the drinking water standards available for the two countries. Regarding surface water, it was found that microorganisms occur at high concentrations; nickel (RSA) and boron (MZ) are other critical parameters. Regarding groundwater, arsenic and lead (RSA) and boron, sodium, and chloride (MZ) are the main critical substances. With regard to micropollutants, their surface water concentrations are much higher than those in European rivers. The highest values were for ibuprofen, acetylsalicylic acid, clozapine, and estriol. Suitable treatment is necessary to produce safe water depending on the main critical pollutants but, at the same time, action should be taken to improve wastewater treatment in rural areas to improve and safeguard surface water bodies and groundwater which are sources for drinking needs.

“…In an unpublished conference paper, Van Wyk, Roychoudhury, Maherry, and Genthe (2012) reported that all village boreholes tested returned salinity levels higher than national and international guidelines for drinking water; six towns were “at risk” of microbial contamination of drinking water; and five had natural fluoride drinking water concentrations above safe limits. Abiye and Leshomo (2013) and Abiye and Bhattacharya (2019) show that several boreholes in the Kamiesberg draw up groundwater with nickel, uranium (U), and arsenic levels—derived from interactions with naturally occurring rocks—higher than WHO recommendations. Winde, Erasmus, and Geipel (2017) connect elevated Leukemia rates in the fairly close‐by town of Pofadder to human‐borehole‐livestock interactions that act to concentrate U ingested by humans (Winde et al, 2017).…”

Water, justice, and wellbeing in the Kamiesberg, Namaqualand: Reflecting on local histories in the context of the Anthropocene

This paper explores relationships between water and well-being in the Leliefontein Pastoral Area, Namaqualand, South Africa. Despite its geographical focus, it nonetheless articulates with broader regional and national debates around water in the Anthropocene. As a positive response to calls for water justice in South Africa, the paper argues for the need for water justice that is attuned to the particularities of South Africa's complex social-ecologies. In order to make this case, the paper explores a regional literature rich in works in the disciplines of environmental history, anthropology and ecology that demonstrates deep entanglements between water, dispossession of land, and oppressive power in the Leliefontein Pastoral Area, and Namaqualand more generally. Because of the histories and ways of life it describes, the literature underscores the need to consider wellbeing as it relates to water in varying forms-as that which flows through pipes and taps, but also that which cycles through the air, falls on the ground, is taken up by plants, and eaten by stock animals. A consideration of Leliefontein's water history also surfaces the historically delimited nature of water that is primarily known as a natural resource, measured in liters and assessed in terms of its microbial and chemical contents. Other kinds of waters exist and persist in the area and are also vital to how many people experience and think about their own wellbeing. This becomes especially significant in the face of expected effects of climate change in the region.

According to a recent report by WHO, the countries which still have a limited access to water for drinking purposes are mainly those in the Sub-Saharan region. (Potential) water sources for drinking needs may contain different contaminants. In this context, the current study consists in an overview of the quality of surface water and groundwater in the Republic of South Africa (RSA) and Mozambique (MZ) and provides the variability ranges of the concentrations of the main pollutants in the two countries. Chemical and physical characteristics, concentrations of macropollutants, inorganic compounds (metals) and selected microorganisms were collected for surface water and groundwater and compared with the standards for drinking water set in the two countries. It was found that in surface water, microorganisms were always at very high concentrations. In addition, nickel (in RSA) and boron and chlorine (in MZ) were the most critical compounds. It emerged that in groundwater, arsenic, lead and chlorine (in RSA) and boron, sodium and chlorine (in MZ) were the main critical pollutants. Adequate treatments in the construction of new drinking water plants in rural areas should be selected on the basis of these most critical compounds and their observed variability over time.
