Government to act after traces of HIV meds found in SA water sources
The Department of Water and Sanitation (DWS) has confirmed it will engage North West University (NWU) on a groundbreaking study that detected traces of anti-retroviral (ARV) medication in several local water sources.
The report, titled 'Quantification, fate and hazard assessment of HIV-ARVs in water resources', was submitted to the Water Research Commission and compiled by NWU's Unit for Environmental Sciences and Management and the Africa Unit for Transdisciplinary Health Research.
Key concerns raised:
• High levels of HIV drugs, especially lopinavir and efavirenz, were found downstream of wastewater treatment plants;
• These concentrations exceed global safety norms;
• The drugs likely originate from SA's large-scale HIV treatment programme, the world's largest.

The study attributes the contamination to municipal wastewater systems, which were not designed to remove pharmaceutical compounds like ARVs. This failure results in untreated traces entering rivers and water bodies.
The environmental risks highlighted the presence of ARVs in natural water sources, which pose hidden health and ecological risks, particularly to aquatic life and water treatment processes.
The findings included:
• Developmental damage in freshwater snails exposed to ARVs;
• Disruption of bacteriophages, viruses that help regulate bacteria during wastewater treatment;
• Increased risk of bacterial blooms, which reduce overall water quality.
'The consumption of any exogenous drug by an organism in sufficient quantity might interfere with metabolic regulation,' the report warns.
The DWS reiterated it will engage NWU, the Water Research Commission, and the Department of Health to assess the implications and recommend interventions.

DWS to probe presence of ARVs in water after university study
DWS to probe presence of ARVs in water after university study The Department of Water and Sanitation (DWS) says it will engage the North West University (NWU) on the study findings of traces of anti-retroviral (ARV) medicines in water resources. The research was conducted by the NWU's Unit for Environmental Sciences and Management and the Africa Unit for Transdisciplinary Health Research. It found that ARVs appear to be entering water resources through municipal wastewater treatment systems, which were usually not designed to remove such chemicals. The report titled, 'Quantification, fate, and hazard assessment of HIV-ARVs in water resources', revealed significant concentrations of ARVs in water sources, particularly downstream of wastewater treatment plants. The drugs most frequently detected were lopinavir and efavirenz, with concentrations at some sites far exceeding global norms. According to the study, this is attributed to South Africa's large-scale HIV treatment programme, the most extensive of its kind worldwide. The research highlighted alarming effects on aquatic ecosystems and wastewater management systems. Freshwater snails exposed to ARVs exhibited altered embryonic development, while bacteriophages – viruses critical to controlling bacteria in wastewater treatment – were significantly impacted. 'Such disruptions could lead to bacterial bloom and reduced water quality. The consumption of any type of exogenous drug by any organism in sufficient quantities may intervene with the regulation of metabolic systems and bring about adverse effects. The presence of antiretrovirals in water can be considered a hidden or latent risk,' the report noted. The report was submitted to the Water Research Commission (WRC). The DWS said it will engage the university on its findings and potential impacts. 'This will be done in conjunction with the Water Research Commission and the Department of Health,' the department said in a statement on Wednesday. – At Caxton, we employ humans to generate daily fresh news, not AI intervention.

SA's water contaminated with microplastics, chemicals and ARVs
The grim details were revealed in several studies commissioned since the year 2000. South Africa's water resources and drinking water have been contaminated with microplastics, chemicals, pharmaceuticals and anti-retrovirals (ARVs) that could pose risks to human health and the environment. The grim details were revealed in several studies commissioned since the year 2000 by the Water Research Commission (WRC), an entity of the department of water and sanitation (DWS), along with local and international research organisations. Studies The studies were commissioned to probe the presence of contaminants of emerging concern (CEC) in water resources and drinking water. One of the studies related to anti-retrovirals (ARVs) was undertaken by the University of North West. ARVs The study found traces of ARVs in samples taken from rivers and potable water sources. South Africa has rolled out a massive programme to curb HIV and Aids, including access to ARVs to reduce the risk of the onset of Aids. In a statement, water and sanitation department spokesperson Wisane Mavasa said that traces of ARVs are entering municipal sewage systems and passing through these systems into rivers. 'This can be attributed to the pharmacological process where the active part of the medication is absorbed by the body, leaving the residual to be discharged from the body, subsequently finding its way into the sewage system. 'These traces of ARVs can then also be present in water that has been extracted from rivers by municipalities to be treated and supplied as potable water,' Mavasa said.

'The traces of pharmaceuticals, microplastics and other such CECs that have been found in water resources in South Africa are very small, measured in nanograms (one billionth of a gram). Conventional water and wastewater treatment technologies are designed to remove much larger contaminants such as particles of faeces and bacteria.' The study, commissioned by the WRC and carried out by North West University, found that: Almost all the concentrations in drinking water samples at the test sites were below limits of quantification. The most frequently detected compound was fluconazole (28 detections from 72 samples), with concentrations ranging between 0.06-1.8 μg/L (nanograms per litre) Nevirapine and efavirenz were the second most detected compounds, both with 22 detections out of 72 samples However, on average, lopinavir and efavirenz had the highest concentrations of the compounds analysed, while Didanosine and zidovudine were the least detected compounds (2 and 6 detections out of 72 samples). Waste Mavasa added that higher concentrations of traces of ARVs were found downstream of wastewater treatment plants. 'This means that the municipal wastewater treatment works are not removing them, because most existing wastewater treatment works have not been designed to remove CECs. Low concentrations of ARVs were found in some of the drinking water samples. 'There is a possibility that high concentrations of ARVs in sewage or municipal wastewater might reduce the effectiveness of the wastewater treatment works in removing bacteria from the wastewater. Further research is required in this regard,' Mavasa said. ALSO READ: Joburg Water warns Phumlamqashi it will not reconnect illegal connections Drinking water Mavasa said that while the presence of ARV residues in drinking water is harmless, prolonged exposure to the broader population may lead to antimicrobial resistance, a subject of ongoing research. 'Pharmaceuticals such as ARVs are drugs used to treat diseases – they do not cause diseases. Therefore, the presence of traces of ARVs in the water will not result in people contracting HIV. 'At present, there is limited knowledge of environmental toxicity, potential adverse effects on ecosystems and viral resistance of these compounds. The study did not find any ARVs in fish,' Mavasa said. No regulation Mavasa said while CECs is a growing global problem and area of attention around the world, globally the level of CEC compounds in water is generally not yet regulated which is partly due to their presence often being below quality detection limits. 'However, due to their continuous production, lack of appropriate disposal, constant input into the environment and presence in water resources, albeit in small concentrations, there is now increasing global research into the issue.' Mavasa said development of methods and techniques to accurately trace these elements in water is one of the key focus areas of global research, adding that research is also being done on effective methods of treatment of the problem, including advanced membrane systems.
