Whereas River Nyamwamba in Western Uganda is well known for the destruction of property and loss of life whenever it overflows, the environmental effects are less known and could be more lethal
The mining and processing of copper in Kilembe, Western Uganda, from 1956 to 1982 left over 15Metric Tonnes of tailings containing cupriferous and cobaltiferous pyrite dumped within a mountain river valley. In addition, underground Kilembe mine water is pumped to the land surface or allowed to flow by gravity into surrounding agricultural soils and water bodies. The study was conducted in Kilembe mine, Kasese district to assess the impact of Kilembe mine and the wastes (tailings) on soil quality, water quality, foods frown, forage and local people exposure. The samples collected included soil, water, foods, forage, sediments and toe nails from local volunteers.
Sample analysis was conducted from the school of biosciences, Nottingham University, UK. The study found high levels of metal concentration especially copper, cobalt, nickel, zinc, arsenic and lead in agricultural soils, public water sources, house dusts and sediments in water. Aluminium and Iron metals were more abundant in public water sources. The metals were not only originating from mine tailings but also underground Kilembe mine water. The leachate water at Kilembe mine also contain large amounts of metals especially copper, iron and aluminium.
The foods and forage grown contained significantly higher concentrations of copper, cobalt, zinc, possibly taken up during growth and accumulated in the foods which could lead to consumption of the same elements by local people. Indeed, tests on human toe nails from Kilembe area volunteers confirmed that local people were more exposed to the mine metals especially copper, cobalt and nickel. Children were more exposed than adults.
It is on this note that the following policy recommendations are made;
1. There is need for enforcement of proper waste storage and disposal protocols 2. Local people living in contaminated environments should be sensitized on the dangers so that they make informed decisions 3. There is need for construction of a containment all around Kilembe tailing sites and land filling with soil so as to prevent erosion of tailings into agricultural soils and water 4. There is urgent need to treat Kilembe mine underground water before it is discharged into River Nyamwamba 5. There is need to implement remediation activities for soils along River Nyamwamba and below tailings
Summary of findings
Water quality Over 25 % of domestic water samples collected and 40% of River Nyamwamba waters along the mine area and downstream exhibited Cobalt concentrations exceeding the Wisconsin (USA) drinking water thresholds of 40 μgL-1. Almost all water samples upstream of River Nyamwamba exceeded UK recommended Iron and Aluminium concentrations in drinking water. Most domestic water samples (67%) exceeded recommended drinking water thresholds for Aluminium, Iron and Cobalt.
Forage Elevated concentrations of Iron, Cobalt, Copper, Zinc and Lead were found in forage grasses collected along the mine area and downstream. The high levels of metal in forage could affect the health of animals and will also be reflected in the milk and beef produced in Kilembe area exposing consumers to metals.
Human exposure Trace elements concentrations (mg kg-1 dw) were found in toe nails of 15 adults and 12 children from the Kilembe copper mining district in Western Uganda. Control samples were from 5 children aged 9-14 years and 5 adults aged 20-60years. The toe nails clearly confirmed exposure of the local people with children being more exposed and affected than adults.
Today, Monday 18th May 2026, most students will begin their End of Semester Two Examinations, and they have been encouraged to remain confident and calm during the examination season.
Data from the University Counselling and Guidance Centre shows that even the best-prepared students experience anxiety, pressure, fear of failure, sleep difficulties and emotional exhaustion during examinations.
Addressing students during a pre-examination mental health workshop organised by the Mastercard Foundation Scholars Program at Makerere University on 15th May 2026, Prof. Buyinza Mukadasi, Academic Registrar, reminded students that their mental health is far more important than any grade.
“This workshop comes at the right time. I encourage all students to understand that your worth is not defined by a single examination or grade. Examinations are only one part of your educational journey. What matters equally is your ability to remain healthy, focused, ethical and hopeful throughout the process,” Prof Buyinza, said.
Prof. Buyinza shared practical tips to help students avoid fatigue and excessive stress during this period.

“Prepare a realistic reading timetable and avoid last-minute cramming. Take short breaks while studying to allow your mind to recover and improve concentration. Get adequate sleep and avoid excessive consumption of caffeine and energy drinks,” he noted.
During the session, he also encouraged students to engage in light physical activity, stretching or short walks to refresh their minds and reduce tension.
“Maintain a positive mindset and avoid comparing yourself excessively with others. Stay connected with supportive friends, family members, mentors or counsellors whenever you feel overwhelmed,” Prof. Buyinza advised.
He reaffirmed the University’s commitment to supporting students not only academically, but also in their mental and psychosocial wellbeing, encouraging learners to seek help from counsellors, lecturers, mentors, peers, family members and available support systems whenever necessary.
Speaking at the event, Ms. Prossy Nakayiki, the Deputy Academic Registrar in charge of Examinations and Transcripts warned students against examination malpractice and urged them to uphold academic integrity.

“Anxiety should never push anyone into examination malpractice, do not enter an examination room with a smart watch, phone or any hidden paper commonly known as bullets. Preparation, honesty, rest and self-belief remain the best approaches to success,” Ms. Nakayiki, said.
She also advised students who had not yet printed their examination cards to do so early, noting that delays at the last minute could cause unnecessary panic and disorganisation.
In her presentation about the reality of examination stress and coping strategies, Connie Evelyn Kharono, a Counselling Psychologist at the Counselling and Guidance Center, called upon students to adopt the 5, 4,3,2,1 Ground technique before an exam or intense study session.

The 5, 4,3,2,1 ground technique, is one of the easiest mindfulness strategies designed for managing stress and anxiety, as it can be done almost anywhere and at any time. You name 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell and 1 you can taste.
She advised students to focus on what they can control.
“You can control your study schedule, your sleep and how kindly you speak yourself. You cannot control the exact questions that will be on the paper, so channel your energy only into the preparations you can influence,” Ms Kharono, said.
Students participate during the workshop.
Ms Kharono encouraged students to maintain a regular sleep schedule and ensure that they are eating balanced meals and staying hydrated.
Ms Christine Nimusiima, a senior Psycho-Social Officer at the Mastercard Foundation Scholars Program at Makerere University, called upon the students to practise positive self-talk and maintain a healthy mindset.

“During this examination season, avoid comparing your revision progress or predicted grades with your peers. Your only competition is who you were yesterday. Take a deep breath, trust in the work you have done and remember that you have the resilience to succeed. Best of luck with your preparations,” Ms. Nimusiima said.
