Rand Water has allayed fears of ARV-contaminated drinking water in Gauteng.
Recent research by North-West University found a significant concentration of ARVs in SA water sources. A high number of South Africans are currently on HIV/ Aids treatment, leading to traces of the chemical entering sewage systems.
Water and sanitation department spokesperson Wisane Mavasa said this week that 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.
Rand Water on ARVs
Rand Water said it had been monitoring ARVs since 2015 and confirmed that it had located the chemicals in natural waters located downstream of wastewater treatment plants. However, the utility takes water from the Vaal Dam, which is upstream of these plants.
'Rand Water has not detected ARVs at the point of abstraction in the Vaal Dam and not in any of its treated final drinking water.'
It assured the public that its drinking water is safe for human consumption and complies with water standards.
'Rand Water remains committed to ongoing research around emerging contaminants in source waters. This is achieved through active participation in national research projects and funding of university chairs in water utilisation, organic chemistry, and public health.'

Government to address contamination if needed
Speaking in Parliament on Tuesday, the water department said it would develop strategies to address contamination, if necessary. This would include working with researchers and the Water Research Commission.
'Most wastewater treatment works were designed some time ago, and they weren't designed with this high level of antiretroviral chemicals being in sewage in mind,' the department's director-general Sean Phillips explained.

'No health risk': Government assures after ARVs were found in water sources
The Department of Water and Sanitation (DWS) has assured the public that the presence of anti-retroviral (ARV) residues in drinking water poses no health risk and cannot result in HIV transmission. This comes as a study conducted by the North West University (NWU) found measurable levels of ARV residues in some of the country's water sources. The report by the NWU's Unit for Environmental Sciences and Management and the Africa Unit for Transdisciplinary Health Research, titled 'Quantification, Fate, and Hazard Assessment of HIV-ARVs in Water Resources', revealed that ARVs are entering the water supply primarily through municipal wastewater treatment systems. As per the study, the most detected ARVs included lopinavir and efavirenz, with concentrations at some sites far exceeding global norms. The study found that concentrations of ARVs in some water sources exceeded acceptable thresholds, posing potential long-term health risks to humans, and the team emphasised that the current wastewater treatment processes are inadequate for removing these bioactive compounds, highlighting the need for technological advancements. 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 contaminants of emerging concern (CECs), the Department of Water and Sanitation, together with the Water Research Commission, said in a joint statement. 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. Following concerns, the Department of Water and Sanitation and the Water Research Commission have clarified that the presence of ARV residues in drinking water is harmless, 'although 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.' According to DWS, the issue of contaminants of emerging concern in water not only affects South Africa but 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. This is partly due to their presence often being below water 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. 'Traces of pharmaceuticals, microplastics, and other such CECs that have been found in water resources in South Africa are tiny quantities, 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 department added.

Health expert warns of increasing chronic illnesses among young adults
The global observance of World Chronic Disease Day on July 10th raises awareness about the impact of chronic diseases such as diabetes, heart conditions, and high cholesterol. Medical advisor Dr Lee Moses from Advisory Risk and Quality Management says for a long time, these conditions were most common among the elderly. But recently they are becoming common among younger, working-aged South Africans. 'In fact, 20% of deaths between the ages of 35 and 64 are attributed to chronic diseases, with hypertension being the most prevalent chronic health condition. 'Although preventable, these diseases are lifestyle-related and, in most cases, lifelong. However, they don't have to be debilitating. With the right lifestyle choices, many people can live long, fulfilling lives despite a diagnosis,' Moses said. The impact of chronic diseases: Living with a chronic condition includes managing symptoms daily. Moses said, 'Individuals living with hypertension (high blood pressure) must be careful to control stress and diet to avoid rising blood pressure. For those living with diabetes, this involves regularly checking blood sugar levels and monitoring their diet. Symptoms of cardiovascular or heart disease may include fatigue, shortness of breath and an increased risk of serious complications such as heart attacks or strokes. 'These illnesses not only affect physical health but also how individuals perform at work, their mental state and, ultimately, .and, ultimately, their ability to engage socially. 'The strain of managing a chronic condition can impact one's emotional health as well, often leading to anxiety and depression,' he said. Lifestyle changes that can make a difference: While medication and regular health check-ups are important, lifestyle habits serve as the foundation for long-term health. Moses shared the following tips on making small changes for big results. Eat right: Avoid consuming processed foods with added sugar, salt and saturated fats, which can increase blood pressure, cholesterol and blood sugar. Instead, consume more unprocessed foods such as fresh fruits and vegetables, lean proteins, whole grains and healthy fats. Move more: Make time for physical movement like walking, swimming or cycling for a minimum of 30 minutes a day. Exercising improves your heart health, controls blood sugar, and reduces blood pressure. Exercise also increases energy levels and supports mental health. Manage stress levels: Try to minimise stress as much as possible. Regular stress leads to increased blood pressure, poor sleep, and unhealthy eating habits. Activities such as deep breathing, meditation, yoga or keeping busy with hobbies are also effective ways of reducing stress. Sleep well: Prioritising rest and relaxation is as important as diet and exercise. Seven to nine hours of sleep helps to regulate the body, as well as manage hormones, blood sugar levels and blood pressure. Insufficient sleep increases the risk of developing chronic illnesses or complicating existing conditions. Stay connected: Support from family and friends is powerful in reducing emotional burdens. Stay in touch regularly, join a support group or consult a therapist to keep your emotions regulated, decrease feelings of loneliness and improve overall well-being. The power of support and prevention: According to Moses, access to comprehensive healthcare and skilled professionals makes living with a chronic condition more manageable. 'Most medical schemes offer support for lifestyle changes, including dietitian consultations, exercise programmes, mental health helplines and chronic disease management services, making it easier to stay on track,' he said. If you have not been diagnosed with a chronic condition, you can help prevent it by taking precautionary measures. This includes regular health screenings and keeping track of your blood pressure, cholesterol and glucose levels. 'Remember the importance of a healthy diet, exercise, rest and connection. Through such consistent changes, we can take back control and lead healthier, more empowered lives,' he concluded. At Caxton, we employ humans to generate daily fresh news, not AI intervention.

Addressing the shortcomings of traditional models in caregiving
Traditional work models, where facilities directly recruit and employ caregivers, often struggle with operational logistics in continuity of care and training. Image: Supplied The demands placed on South African frail care and retirement villages are tougher than ever. These establishments must consistently provide high-quality care while addressing persistent staffing issues and adapting to an increasingly complex regulatory environment. The limitations of traditional care models heavily reliant on individually employed caregivers can no longer be ignored. In response, a strategic shift towards collaborating with experienced healthcare professional service agencies is gaining momentum, providing a welcome pathway for facilities to greatly enhance care provision, optimise operational workflows, and mitigate potential liabilities. Addressing the shortcomings of traditional models Modern senior care facilities face growing challenges that necessitate efficient resource management. Rising operating costs, stricter regulatory demands, and persistent staffing shortages (particularly for specialised roles) create significant operational burdens. To maintain high standards of care and ensure resident well-being, facilities must adopt innovative solutions that address both operational and care-related needs. Video Player is loading.

Advertisement Next Stay Close ✕ Ad loading Exceptional care can only be built on personalised attention, and outsourcing allows facilities to raise their care standards by accessing a pool of highly trained and compliant caregivers in collaboration with a reputable healthcare professional staffing services provider. The right agency partner makes it possible for facilities to prioritise personalised care, ensuring each resident receives the attention required for the best outcomes. Putting personalised care at the top of the quality scaleCaregiving agencies have an important role to play in implementing robust care plans in collaboration with doctors. By placing caregivers who work under the instructions of the facility's matron or registered nurse, agencies assume responsibility for ensuring care plans are followed diligently, while clinical facilitators provide continuous training that ensures caregivers are competent and confident in their roles. Such a collaborative approach greatly enhances resident well-being and safety. With the expertise of such specialist agencies, retirement villages and frail care facilities can be assured that consistent, high-quality care will be delivered, a critical factor in building trust with residents and their families. Ensuring competency, continuity of care and flexibility Traditional work models, where facilities directly recruit and employ caregivers, often struggle with operational logistics in continuity of care and training. Here, staffing shortages due to unforeseen absences can greatly disrupt daily routines. In contrast, partnering with a staffing solutions organisation provides access to a reliable pool of caregivers on demand. A professional agency partner handles all scheduling requirements while ensuring extra caregivers are oriented to the facility. This enables quick replacements (often within two hours) to minimise disruptions and maintain consistent care, while such flexibility also gives the facility the room to scale up or down on caregiving resources in direct response to the changing needs of residents without significant cost. Critically, a key benefit of partnering with a staffing provider is the comprehensive administrative relief they offer. Agencies manage the entire recruitment process, onboarding, payroll, and continuous training, freeing facilities from these burdens. Here, the agency steps in to simplify processes and mitigate risk by handling everything from start to finish, with thorough criminal and reference checks to minimise security risks and comprehensive recruitment processes that ensure caregivers are proficient in English and possess the necessary skills and attributes for the job. Outsourcing to continually enhance personalised care standards One of the most compelling advantages to partnering with a staffing services agency is the fact that the facility has guaranteed access to pre-screened, trained, and compliant caregivers who have been through a rigorous upskilling course to ensure they are well-prepared for the frail care environment. The right staffing partner takes time to understand each facility's unique needs and matches caregivers accordingly, with business unit managers actively participating in the selection process to ensure the perfect fit. Equipped with comprehensive training on essential skills, including dementia care, palliative care and rehabilitation, these caregivers can address the specific needs of residents with confidence and compassion. Their specialised training relieves pressure on facilities and ensures residents receive appropriate care, which enhances family satisfaction. The right partner also employs clinical facilitators designated to provide on-site training and support, so that the facility is assured that caregivers are up to date with the latest care practices and technologies to continuously enhance the overall quality of care. Facilities benefit from collaborative training opportunities, further upskilling their staff at no additional cost. Significantly, these specialised care services can supplement the core offerings of the facility to better meet the diverse needs of residents, attract a broader clientele and strengthen their market position. An essential shift towards high-quality care For the future of senior care, strategic partnerships with healthcare staffing providers are no longer optional, but essential. These collaborations ensure the long-term success of retirement villages and frail care facilities by optimising staffing, enhancing care, and mitigating risks. They are the foundation for delivering exceptional resident experiences and building a culture of safety and trust. These partnerships will allow facilities to meet the demands of today, while building a forward-thinking model for the dignified and compassionate senior care of tomorrow.
