“…Most investigations noted that higher concentrations were found in winter than in summer depending on the typical consumption pattern. The highest values refer to over-the-counter drugs which can be administered without any prescription and thus their use is very frequent and concentrations are found in all the investigated rivers [24]. A comparison with observed values in some European countries [4] shows that concentrations in African surface water are, with a few exceptions, 2-185 times higher than concentrations found in European surface water bodies.…”

“…The collected data are reported in Figures 8 and 9, grouped according to their class. [20,[24][25][26]40,43,45,46,48,49,55,59,60]. It emerges that the most frequently monitored classes were antibiotics (372 values), analgesics and anti-inflammatories (347 values), psychiatric drugs (155 values), and antivirals (154 values).…”

“…It was found that the antivirals nevirapine, efavirenz, and the psychiatric drug carbamazepine, always occurred around 2-13 ng/L in different samples withdrawn from the Dam Hartbeespoort, Gauteng province, over the year It emerges that the most frequently monitored classes were antibiotics (372 values), analgesics and anti-inflammatories (347 values), psychiatric drugs (155 values), and antivirals (154 values). It was found that concentrations of pharmaceuticals may be very high in surface water: this occurs for acetylsalicylic acid (159,900 ng/L, [48]), ibuprofen (84,600 ng/L, [49]), clozapine (78,300 ng/L, [48]), phenacetin (68,300 ng/L, [40]), estriol (46,200 ng/L, [54]), caffeine (33,200 ng/L, [49]) and atenolol (30,000 ng/L, [24]).

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.

“…As to microorganisms, surface water contains high concentrations of all the investigated species. This consideration is not surprising as surface water bodies may receive land runoff from areas characterized by the presence of grazing animals and where manure may be applied, untreated rural and zootechnic wastewater which contribute in terms of microorganisms [27].…”

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.

The growing production and use of chemicals and the resultant increase in environmental exposure is of particular concern in developing countries where there is rapid industrialization and population growth but limited information on the occurrence of emerging contaminants. Advances in analytical techniques now allow for the monitoring of emerging contaminants at very low concentrations with the potential to cause harmful ecotoxicological effects. Therefore, we provide the first critical assessment of the current state of knowledge about chemical exposure in waters of the Southern African Developmental Community (SADC). We achieved this through a comprehensive literature review and the creation of a database of chemical monitoring data. Of the 59 articles reviewed, most (n = 36; 61.0%) were from South Africa, and the rest were from Botswana (n = 6; 10.2%), Zimbabwe (n = 6; 10.2%), Malawi (n = 3; 5.1%), Mozambique (n = 3; 5.1%), Zambia (n = 2; 3.4%), Angola (n = 1; 1.7%), Madagascar (n = 1; 1.7%), and Tanzania (n = 1; 1.7%). No publications were found from the remaining seven SADC countries. Emerging contaminants have only been studied in South Africa and Botswana. The antiretroviral drug ritonavir (64.52 µg/L) was detected at the highest average concentration, and ibuprofen (17 times) was detected most frequently. Despite being the primary water source in the region, groundwater was understudied (only 13 studies). High emerging contaminant concentrations in surface waters indicate the presence of secondary sources of pollution such as sewage leakage. We identify research gaps and propose actions to assess and reduce chemical pollution to enable the SADC to address the Sustainable Development Goals, particularly Goal 3.9, to reduce the deaths and illnesses from hazardous chemicals and contamination.
