Dr Nicholas Pearce, Head of the COVID-19 Task Team at the Universitas Academic Hospital, leads a dedicated team of professionals at the testing and vaccination site of the Universitas Academic Hospital, adjacent to our Bloemfontein Campus.

It is impossible to quantify the number of hours Dr Nicholas Pearce, Head of the COVID-19 Task Team for the Universitas Academic Hospital, spent working in response to this deadly virus since the first case was reported in South Africa last year. 

According to Dr Pearce, who is the Head of the Department of General Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), the initial preparation phase required many hours of brainstorming, planning, and physical hours working on site. He also spent countless hours awake at night trying to come up with solutions for the many challenges faced along the way. This is in addition to being available telephonically twenty-four-seven for any issues related to equipment, staffing, and facilities.

“I was attending a vascular surgery congress in Germany last year January (2020) when China just announced the outbreak of COVID-19. I noticed an increased number of travellers wearing surgical masks at an airport in the Middle East when I was travelling to South Africa. 

“Upon my return to work, I approached management to discuss procurement of PPEs, as it was just a matter of time before COVID-19 would hit South Africa and the rest of the world. When things escalated, I was asked to head the COVID-19 response team at Universitas Hospital,” explains Dr Pearce.

Kind human being with a soft heart

Dr Pearce, who was brought up to always strive to be better, is driven and motivated to succeed. He has a very analytical brain and loves challenges. In fact, he does not believe in problems and only sees challenges. This kind human being can sometimes seem quite tough on the outside, but actually has a very soft heart. 

“I think it is human nature to want to feel needed. I have an inherent urge to help my fellow human beings. This is also the reason why I became a health-care professional and why I am passionate about teaching,” says Dr Pearce. 

With South Africa lagging behind with its vaccination programme, the hard work is far from over for Dr Pearce and his team. Says Dr Pearce: “The initiation of a mass vaccination site posed a whole new set of challenges, which once again required many hours of planning. The initial stages of running the vaccination site required many hours of physical hard work a day. Then there is also the daily operations meeting at 18:00 every weekday to discuss the vaccine roll-out in the province.”

Frustrations and setbacks

For Dr Pearce, this pandemic highlighted the differences between individuals from different social classes in our country. Providing quarantine and self-isolation facilities for individuals who do not have access to such facilities at home is one such example. 

“We all have a right to clean water and good quality healthcare. This also includes a right to oxygen. This right to oxygen has proved to be one of our great challenges in managing this pandemic. Delivery of these large amounts of oxygen has been especially challenging. Some days we require in excess of five tons of oxygen,” says Dr Pearce.

There have been many frustrations and setbacks on this journey, some of which can be quite demoralising and demotivating, but knowing that he is doing something good for his fellow human beings gives this gentle and diligent healthcare worker a tremendous amount of energy. “Positive feedback from patients and colleagues far outshines all the frustrations and disappointments,” concludes Dr Pearce. 


Outside of work

After finishing online meetings at home, Dr Pearce relaxes with his partner by chatting about the day’s events and cooking supper together while enjoying a glass of wine. He also tries to connect with family who lives in Gauteng. Because of work pressures and the pandemic, he has not been able to see them as much.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
