The University of the Free State – Next Generation Sequencing (UFS-NGS) Unit hosted a pioneering scholarly engagement initiative for Grade 11 learners from nine secondary schools in Bloemfontein. The three-day event with the theme "Frontiers of Discovery: Illuminating the Impact of Genomics in Science outreach programme” marked the first comprehensive genomics science outreach initiative in the Faculty Health Sciences.

Coordinated by Prof Martin Nyaga, Head of the UFS-NGS Unit, the programme bridged the longstanding gap through practical NGS exposure and ignited a passion for Science, Technology, Engineering, and Mathematics (STEM) by inspiring the next generation of genomic innovators using combined interactive lectures, laboratory demonstrations, career talks, and hands-on workshops. This allowed learners to directly engage with cutting-edge scientific techniques and genomic technologies, especially the scientific and evolutionally impact of Polymerase Chain Reaction (PCR) and NGS.

The initiative engaged selected Grade 11 learners from the nine schools: Brebner, Ikaelelo and Vulamasango (day 1), Atlehang, Castle Bridge School and Kaelang (day 2) and Eunice, Navalsig, and Lekhulong (day 3).

“This outreach programme marks a significant milestone in community-based genomics education in South Africa by offering high school learners the opportunity to engage with modern genomic sciences before making career decisions. The initiative particularly aimed to nurture future scientists and diversify the country’s STEM talent pipeline.

“This historic programme bridged gaps in scientific literacy and diversity in the Free State and concluded each day with a genomics quiz competition, which tested the participant’s newly acquired knowledge/exposure and provided a fun competitive learning opportunity. Six quiz winners across the three days received special prizes, and all students were awarded certificates of participation,” says Prof Nyaga.

Hands-on exploration and NHLS virology laboratory tour

The training was held at the UFS-NGS Unit in the School of Biomedical Sciences and at the NHLS Virology laboratories, School of Pathology, Faculty of Health Sciences. Each attending secondary school was represented by five Grade 11 learners and a life science’s educator. Each day, 15 learners and three educators observed hands-on practicals, including DNA extraction, PCR, gel electrophoresis, and DNA library preparation for sequencing on platforms such as Illumina MiSeq and NextSeq 2000.

Guided by the UFS-NGS Unit’s team members; Dr Milton Mogotsi, Hlengiwe Sondlane, Mbali Ncube, Nkosazana Shange, Somila Nazo, Sesiyanda Maseko, Surprise Baloyi, Manyi Eyong and Mamello Maku, the learners were exposed to how DNA is extracted and visualised, how the PCR machine works and how DNA libraries are prepared and sequenced.

Furthermore, a guided laboratory tour of the Virology laboratories at the NHLS was provided by Khauhelo Mafa which offered the leaners the opportunity to observe, diagnostic and molecular workflows in action, resulting in a real-time glimpse into world-class medical research and diagnostics, fuelling curiosity about the role of advanced genomics science in disease control.

Inspiration through expert talks

The learners were also inspired by talks from Prof Chris Viljoen, Head of the School of Biomedical Sciences, Prof Zinhle Makatini, Associate Professor and Head of Division of Virology, School of Pathology, and Dr Claudia Ntsapi, Senior Lecturer and researcher in the Department of Basic Medical Sciences at the UFS. Prof Viljoen highlighted the role of science in transforming lives and improving life expectancy, while Prof Makatini gave candid reflections on her professional journey, particularly how she pursued Medical Virology through unwavering determination and excelled to become among the pioneer women specialists in the field in South Africa. Dr Ntsapi inspired the audience with her perseverance from her humble beginnings to earning a PhD in Neurophysiological Sciences against all odds.

The speakers also delivered compelling presentations on the applications of genomics in medicine (e.g.), personalised cancer treatments), public health (e.g.), tracking HIV and COVID-19), agriculture (e.g.), resilient crops), and environmental science (e.g.), ecosystem protection), which resonated well with the learners, educators and the UFS-NGS team. A presentation on diverse career options available at the UFS Faculty of Health Sciences was further provided by Angelique Carson-Porter, a UFS representative from the Department of Nutrition & Dietetics. Her talk on different career pathways in Health Sciences broaden the learners’ horizons, fostering future aspirations.

Dr Emmanuel Ogunbayo, Dr Mogotsi, Thabisa Mpaxa, Nkosazana Shange and Eyong Manyi shared their personal career journey to be at the UFS-NGS Unit, offering advice on academic experiences and opportunities within genomics, bioinformatics, and biotechnology, while answering scholarship queries.

“The career talk opened my eyes. I’m now aiming for a biotechnology degree!” said Neliswa Thwala, a learner from Navalsig CS/S.

Following the enthusiastic response and tangible outcomes of this programme, the UFS-NGS Unit is committed to expanding this initiative, with plans to introduce similar events to other schools and developing sustained mentorship opportunities for learners interested in pursuing genomics-related careers. The UFS-NGS Unit further invites interested partners, sponsors, and stakeholders to collaborate in future outreach and capacity-building programmes to continue bridging the genomics education gap in Africa.

Inspire the next generation

Prof. Nyaga’s closing remarks highlighted the learners’ potential to shape the ‘omics’ workforce and stated the intention of the organising committee to expand the mentorship programmes, fostering a vibrant STEM pipeline. “This initiative represents our vision to make genomics accessible and inspire the next generation of African scientists.”

The success of this programme was driven by the UFS-NGS Unit team and was supported by Distribution Platform in Omics (DIPLOMICS).

Bloemfontein's quality of tap water compares very favourably with bottled water

2009-08-04

The quality of the drinking water of five suburbs in Bloemfontein is at least as good as or better than bottled water. This is the result of a standard and chemical bacterial analysis done by the University of the Free State’s (UFS) Centre for Environmental Management in collaboration with the Institute for Groundwater Studies (IGS).

Five samples were taken from tap water sources in the suburbs of Universitas, Brandwag, Bain’s Vlei, Langenhoven Park and Bayswater and 15 samples were taken of different brands of still and unflavoured bottled water. The samples were analysed at the laboratory of the IGS, while the interpretation of the analysis was done by the Centre for Environmental Management.

“We wanted to evaluate the difference in quality for human consumption between tap water and that of the different brands of bottled water,” said Prof. Maitland Seaman, Head of the Centre for Environmental Management.

“With the exception of two samples produced by multinational companies at their plants in South Africa, the different brands of bottled water used for the study were produced by South African companies, including a local small-scale Bloemfontein producer,” said Prof. Seaman.

According to the labels, the sources of the water vary from pure spring water, to partial reverse osmosis (as an aid to standardise salt, i.e. mineral, content), to only reverse osmosis (to remove salts). (Reverse osmosis is a process in which water is forced under pressure through a pipe with minute pores through which water passes but no – or very low concentrations of – salts pass.)

According to Prof. Seaman, the analysis revealed some interesting findings, such as:

• It is generally accepted that drinking water should have an acceptable level of salt content, as the body needs salts. Most mineral contents were relatively higher in the tap water samples than the bottled water samples and were very much within the acceptable range of drinkable water quality. One of the bottled samples, however, had a very low mineral content, as the water was produced by reverse osmosis, as stated on the bottle. While reverse osmosis is used by various producers, most producers use it as an aid, not as a single method to remove nearly all the salts. Drinking only such water over a prolonged period may probably have a negative effect on the human physiology.

• The pH values of the tap water samples (8,12–8,40) were found to be slightly higher (slightly alkaline), like in all south-eastern Free State rivers (from where the water is sourced) than the pH of most of the bottled water samples, most of which are sourced and/or treated in other areas. Two brands of bottled water were found to have relatively low pH levels (both 4,5, i.e. acidic) as indicated on their bottles and as confirmed by the IGS analysis. The health implication of this range of pH is not significant.

• The analysis showed differences in the mineral content given on the labels of most of the water bottles compared to that found by IGS analysis. The possibility of seasonal fluctuation in content, depending on various factors, is expected and most of the bottling companies also indicate this on their labels. What was a rather interesting finding was that two pairs of bottled water brands claimed exactly the same mineral content but appeared under different brand names and were also priced differently. In each case, one of the pair was a well-known house brand, and the other obviously the original producer. In one of these paired cases, the house brand stated that the water was spring water, while the other (identical) “original” brand stated that it was spring water treated by reverse osmosis and oxygen-enriched.

• Nitrate (NO3) levels were uniformly low except in one bottled sample, suggesting a low (non-threatening) level of organic pollution in the source water. Otherwise, none of the water showed any sign of pollution.

• The bacterial analysis confirmed the absence of any traces of coliforms or E.coli in any of the samples, as was also indicated by the bottling companies. This is very reassuring. What is not known is how all these waters were sterilised, which could be anything from irradiation to chlorine or ozone treatment.

• The price of the different brands of bottled water, each containing 500 ml of still water, ranged between R3,99 and R8,99, with R5,03 being the average price. A comparison between the least expensive and the most expensive bottles of water indicated no significant difference in quality. In fact, discrepancies were observed in the most expensive bottle in that the amount of Calcium (Ca) claimed to be present in it was found to be significantly different from what the analysis indicated (29,6 mg/l versus 0,92 mg/l). The alkalinity (CaCO3 mg/l) indicated on the bottle was also found to differ considerably (83 mg/l versus 9,4 mg/l). The concentration of Total Dissolved Salts (TDS) was not given on the product.

“The preference for bottled water as compared to Bloemfontein’s tap water from a qualitative perspective as well as the price discrepancy is unjustifiable. The environmental footprint of bottled water is also large. Sourcing, treating, bottling, packaging and transporting, to mention but a few of the steps involved in the processing of bottled water, entail a huge carbon footprint, as well as a large water footprint, because it also requires water for treating and rinsing to process bottled water,” said Prof. Seaman.
