Dr Patricks Voua Otomo is the Head of the Ecotoxicology Research Laboratory and Subject Head: Zoology and Entomology in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS).

The month of June is earmarked for the celebration of National Environment Month, with the South African government and captains of industry leading the way by stimulating awareness on environmental issues and challenging everyone to become agents for change. World Environment Day, the biggest annual event of the United Nations Environment Programme (UNEP), is commemorated on 5 June, with the aim of galvanising positive environmental action. The University of the Free State (UFS) – through researchers from the Afromontane Research Unit (ARU) housed on the Qwaqwa Campus of the UFS – is playing its part in the fight against pollution, and especially water pollution in the eastern Free State.

The ARU initiated a research project in 2021, focusing on the assessment of the quality of local natural water resources in order to foster sustainable development in Phuthaditjhaba, and because of the recurring challenges pertaining to water quality and quantity in the Maluti-a-Phofung (MAP) Local Municipality. For the first such project focusing exclusively on pollution issues in a select Afromontane region – led by Dr Patricks Voua Otomo, Head of the Ecotoxicology Research Laboratory and Subject Head: Zoology and Entomology in the Faculty of Natural and Agricultural Sciences – a vibrant team of ARU scientists and students set out to determine the ecotoxicological and bacteriological state of water resources in MAP. With the permission of MAP, ARU researchers and students were allowed access to municipal wastewater treatment plants in the towns of Phuthaditjhaba and Harrismith, and ethical clearance from the UFS permitted limited environmental sampling and laboratory testing using live organisms such as snails and earthworms.

Focusing on the quality of natural water bodies
In November 2016, Ms Portia Mosolloane (2016 honours student) presented the preliminary findings of the project at an ARU colloquium held in the Golden Gate Highlands National Park. Her work has drawn attention to potential localised incidents of terrestrial contamination linked to sewage sludge management in the region. Those early findings were published internationally, and in May 2018, Ms Mosolloane went on to present her research at the 28th Annual Meeting of the Society of Environmental Toxicology and Chemistry (SETAC) in Rome, Italy.

In an attempt to mitigate sewage sludge-induced soil pollution, Ms Nomasonto Dlamini (master’s student) conducted research from 2018 on the potential beneficial effects of biochar amendment on the sewage sludge as an alternative management strategy. The results revealed that mixing biochar with sewage sludge prior to open-air storage would significantly decrease the toxic effects on terrestrial organisms such as oligochaetes. This work is still ongoing, although in May 2019, Ms Dlamini presented some of her findings at the Fifth World Congress on Risk Development and Resilience in Cape Town.

From the start, an important focus of our research has been the quality of natural water bodies in our region and its ability to support life. In 2020, Ms Mosolloane graduated cum laude with a Master of Science, having successfully established that, particularly along polluted and degraded sections of our rivers, the diversity of riparian invertebrate was heavily skewed and reduced. Her work on water quality has suggested that our failing wastewater treatment plants (due to ageing, capacity overload, and poor management) are contributing to the release of pathogenic bacteria such as Escherichia coli in the local rivers.

Mr Mbuyiselwa Moloi (a 2020 Master of Science graduate from the project) found through his research that wastewater treatment plants only contribute partially to river pollution in the region. His work, focusing on metal pollution in the Elands River (Phuthaditjhaba) and the Wilge River (Harrismith), established that although there is evidence of metal enrichment after wastewater processing by the treatment plants, some of the metal in the rivers emanates from the communities that, due to the lack of adequate refuse removal services, often dispose of their household waste directly into the rivers. Mr Moloi’s research was presented at the 2019 International Mountain Conference in Innsbruck, Austria, and was subsequently published in the International Journal of Hygiene and Environmental Health in 2020.

Ms Matseleng Semase (a 2020 Master of Science graduate from the project) worked on establishing whether the quality of the effluent released from the local wastewater treatment plants was conducive to supporting aquatic life. Using a snail species in the laboratory, she found that although of substandard quality, the effluent released from the treatment plants did not hamper growth and reproduction in her test organism. This pointed to the fact that corrective measures could still be taken to reduce the harmful impact of wastewater management processes on river health in the eastern Free State. Ms Semase’s work was presented at the 9th SETAC Africa Biennial Conference held in Cape Town in 2019, and her findings were submitted for publication in Environmental Science and Pollution Research.

First such project focusing exclusively on pollution issues
Some of our findings infused new life into the project, steering our work in unexpected directions. Early in the project we came to realise that there was a paucity of research focusing on pollution in mountain areas in South Africa and in Africa at large. Mr Hendrik Stander joined the project in 2019 as a master’s student. His task was to work on the development of fast and reliable behavioural testing protocols that could be used in the project. His preliminary findings were presented at the 40th annual meeting of SETAC North America in Toronto, Canada, and were subsequently published in the Bulletin of Environmental Contamination and Toxicology. Ms Sanele Mnkandla, who joined the project as a PhD candidate in 2020, is working on proposing water remediation strategies that could help improve the state of the rivers in the region. She recently submitted a review article on the topic for publication in Environmental Evidence. Another review article in the making and focusing on literature evidence of mountain pollution in Africa, is the brainchild of Dr Ozekeke Ogbeide, a collaborator from the University of Benin (Nigeria), who co-supervised several students and co-authored some of the scientific publications from the project.

This ongoing research, under the auspices of the ARU, is the first such project focusing exclusively on pollution issues in a select Afromontane region. With Ms Dlamini, Mr Stander, and Ms Mnkandla still actively involved in the project, we look forward to finding more answers to the environmental challenges of the eastern Free State and to working together with MAP towards environmental sustainability in the region.

With the recent procurement of SAB by Anheuser-Busch InBev SA/NV (AB InBev), a Belgian transnational beverage and brewing company, the 500L educational brewery located at the SAB Cyril Ramaphosa World of Learning, became available for donation. After an initial shortlisting of three universities, the SAB World of Learning Brewery was awarded to the University of the Free State (UFS) to be managed by Kovsie Brewing.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, approved the application for a micro-manufacturing liquor licence right in the middle of campus, which effectively put the UFS bid in a class of its own. It is part of her vision that entrepreneurial activities must be visible on campus”

Sixteen universities were approached to obtain the brewery for their respective campuses.

Kovsie Brewing is an initiative started by postgraduate students at the UFS Department of Microbial, Biochemical and Food Biotechnology in 2012. The main objective of this initiative was to expose BSc students to brewing as a practical application of the scientific fields presented at the department.

Label mock-ups made by
Dr Jan-G Vermeulen from
Kovsie Brewery entered into
the yearly  SAB Intervarsity
Brewing Competition. Kovsie
Brewing has won the best label
competition in 2013, 2014 and 2015
and was placed in the top three in
2016 and 2017.


First brewing and fermentation school
Dr Errol Cason, project leader at Kovsie Brewery, said: “Over the past five years the small-scale experimental brewery has steadily grown to the point where we obtained institutional support to establish the first Brewing and Fermentation School at the university.

Dr Cason explains that the primary role of Kovsie Brewing is to establish an accredited fermentation-based curriculum at the UFS to educate undergraduate and postgraduate students in the scientific process involved in the production of beer. “In addition, the donation enables Kovsie Brewing to provide practical job-related training and skills development on industrial grade equipment,” he said.

Emphasis on entrepreneurship
The secondary role is for Kovsie Brewing to function as a multi-disciplinary platform to stimulate the interaction between students from various fields of study. Currently Kovsie Brewing has well-established cooperative projects with both Marketing and Entrepreneurship programmes.

“In the future, Kovsie Brewing will expand on these multi-disciplinary interactions by incorporating other departments of the UFS with the focus on product development, logistics, as well as the legal aspects concerned with brewing,” Dr Jan-G Vermeulen from the Kovsie Brewery team said.

Corporate social investment representatives from AB InBev recently visited the university. Among others they met Drs Vermeulen and Cason. During their visit they also looked at other university projects, including the Department of Paediatric and Child Health and the Universitas Hospital, the Engineering Sciences Department and the Naval Hill Planetarium.

Khosi Mogotsi from AB InBev said: “It was wonderful to experience the passion with which UFS staff do their work.”
