Press Release: New method offers rapid monitoring of contamination in drinking water

Published

on

12th October 2021: Scientists have developed a reliable new method to monitor the risk of contamination in drinking water which gives immediate results, enabling global communities to respond rapidly and help reduce their exposure to waterborne diseases.

Drinking water contaminated with human and animal faeces is consumed by at least two billion people worldwide. This pollution is responsible for outbreaks of waterborne diseases that remain common, even in high-income countries.

For decades, standard approaches to test water supplies have used bacteriological indicators of faecal contamination, most commonly thermotolerant coliform bacteria known as TTCs. Analysis of these indicators requires use of sterile equipment and culturing techniques, which practically limit the frequency of water sampling so that contamination events can be missed. Time lags of 1 or 2 days before results are returned mean that people can already have been exposed to the faecal contamination.

A new study, published this week in Water Research by a collaborative team from Makerere University, the British Geological Survey, and University College London, shows how a technique exploiting the fluorescent properties of microbiological materials in water provides an easy-to-use method to test for faecal contamination.

Co-author Jacintha Nayebare, PhD student at Makerere University said, “In-situ fluorescence spectroscopy provides an instantaneous assessment of faecal contamination allowing rapid feedback to consumers that could reduce exposure of consumers to faecally contaminated drinking water.”

The team examined changes in water quality over a 14-month period from 40 sources supplied by groundwater in Lukaya Town of south-central Uganda. The results show not only that in-situ fluorescence provides an instantaneous measure of faecal contamination but also that it is a more reliable measure of the risk of faecal contamination than TTCs.

Co-author, Dr. Robinah Kulabako from Makerere University’s Department of Civil and Environmental Engineering said, “this rapid, robust method of monitoring the risk posed by faecal contamination has enormous implications in Uganda not only for untreated water sources such as wells and springs thereby, enabling communities to respond rapidly to contamination events but also for low-cost, continuous monitoring of piped water supplies.”  

This research builds upon field studies conducted by the team in a network of urban observatories in Senegal, Kenya and Uganda under the AfriWatSan project, supported by The Royal Society and DFID, as well as research in the UK, India, and Zambia funded by Natural Environment Research Council.

Lead-author, James Sorensen from the BGS and UCL said: “the ability to test in-situ fluorescence as an indicator of faecal contamination risk in a wide range of environments and conditions has greatly improved both the evidence base for this method of water quality monitoring and our understanding of what fluorescence observed in water means.”

A selection of the newly installed micro studio equipment on display during the official handover ceremony held at CEDAT on Wednesday, 25th June 2025.

The College of Engineering, Design, Art and Technology (CEDAT) at Makerere University has signed a Memorandum of Understanding (MOU) with the Project Management Committee of the “Enhancing the Distance Education Environment at Makerere University” initiative. This agreement formalizes the operational and managerial framework for the newly installed micro studio at CEDAT, aimed at strengthening the university’s digital learning infrastructure.

Assoc. Prof. Kizito Maria Kasule, Deputy Principal of CEDAT, signed on behalf of the college, while Dr. Shon JinGon, Project Manager at the Korea Institute for Development Strategy (KDS), represented the implementing partner during an event held on Wednesday, 25th June 2025.

Uganda Urged to Strengthen OSHE Enforcement Amid Rising Workplace Injuries

Published

on

Dr. Abubaker Waswa Matovu (R) Head of the Department of Computer and Electronics Engineering at Makerere University, emphasized the importance of the training in promoting workplace safety.

In response to Uganda’s growing workplace safety concerns, staff at the College of Engineering, Design, Art, and Technology (CEDAT) participated in an Occupational Safety, Health, and Environment (OSHE) training session aimed at increasing awareness and improving adherence to safety standards in professional and academic environments.

The workshop, organized by the School of Engineering, was part of a larger effort led by the OSHE Centers of Excellence, an initiative launched at Makerere, Kyambogo, and Busitema Universities on May 4, 2023. This program seeks to enhance workplace safety education, with a focus on hazard prevention, PPE usage, risk mitigation, and integrating OSHE principles into engineering curricula and industrial practices.

Speaking at the training, Dr. Abubaker Waswa Matovu, Head of the Department of Computer and Electronics Engineering at Makerere University, emphasized the importance of the training which was aimed at creating awareness about the need for the College, the university and the industry to proactively plan for safety at the place of work. It was indicated that Uganda was faced by alarming workplace injury rates, with over 25,000 workers suffering from job-related injuries annually, yet fatality statistics remain largely unreported.

Dr. Matovu highlighted the urgent need for OSHE integration in higher education, pointing out that 99% of engineering and science graduates enter the workforce without formal safety training. This lack of preparedness has led industries to withdraw internship placements, fearing liability if trainees suffer injuries or fatalities while on the job, he noted.

The NBD team and their hosts led by Dr. Robinah Kulabako pose for a picture at the CEDAT Block

Makerere University’s Department of Civil and Environmental Engineering, has partnered with the Nile Basin Discourse (NBD) to collaborate on a World Bank-funded, two-year project aimed at improving transboundary water resource management in East Africa.

During a meeting held on 5th June 2025 at CEDAT, Eng. Sylvesta Matemu, head of NBD, engaged with Makerere University representatives, including Dr. Philip Nyenje and Dr. Seith Mugume, to discuss strategies for effective implementation. The project seeks to employ citizen science approaches to involve local communities in water governance, data collection, and policy formulation.

The team also met with Prof. Dorothy Okello, Dean of the School of Engineering, and Dr. Robinah Kulabako, Chair of the Department of Civil and Environmental Engineering, to explore key areas of collaboration. Experts stressed the importance of regional cooperation in water management, citing growing concerns over resource sustainability and environmental challenges.
