Africa’s water quality has been under growing scrutiny, and in South Africa, the situation has become especially concerning. From municipal tap water to borehole supplies, contamination issues are raising alarm over drinking water safety and public health risks.
According to AfriForum’s 2024 Blue and Green Drop Report, only 87% of South Africa’s drinking water is considered safe — well below ideal standards. This highlights urgent problems with water treatment, infrastructure maintenance, and contamination control.
Declining Municipal Water Quality in South Africa
Across many regions, municipal water quality has been deteriorating. Residents report brown or discoloured water, often linked to iron and manganese. While these minerals mainly affect taste and appearance, other detected contaminants — such as nitrates and sulphates — can cause serious health issues.
-
Nitrates: Linked to methemoglobinemia (“blue baby syndrome”) in infants.
-
Sulphates: Can cause diarrhoea and dehydration at high levels.
The Water Research Commission’s 2023/24 Annual Report warns that excessive nitrate and sulphate levels remain a significant problem, particularly in rural and underserved communities.
Microbiological Contamination – E. coli and Cholera Risks
One of the most serious Africa water quality issues is microbiological contamination. Pathogens such as Escherichia coli (E. coli), faecal coliforms, and Vibrio cholerae (cholera) have been detected in municipal supplies.
-
E. coli & faecal coliforms: Indicate sewage contamination.
-
Vibrio cholerae: Responsible for cholera outbreaks.
The Department of Water and Sanitation’s 2023/24 Annual Report reveals that many municipalities fail to meet microbiological safety standards, putting communities at risk of waterborne diseases.
Borehole Water Quality – Not Always Safe
As municipal supplies falter, more South Africans are relying on borehole water. While it can be a vital alternative, it’s not free from contamination risks.
Common borehole water hazards include:
-
Agricultural runoff carrying pesticides and fertilisers
-
Heavy metals such as arsenic and lead
-
Fluoride and other naturally occurring minerals at unsafe levels
-
Bacterial contamination from nearby septic systems
The Department of Water and Sanitation has raised concerns about heavy metals and bacterial contamination in borehole water, stressing the need for regular water quality testing.
SANS 241 – South Africa’s Water Quality Standard
The South African National Standard (SANS) 241 sets the country’s drinking water safety requirements:
-
Zero tolerance for E. coli and faecal coliforms.
-
Defined limits for iron, manganese, nitrates, and sulphates.
-
Compliance with chemical and microbiological safety parameters.
Adhering to SANS 241 is essential for ensuring safe drinking water for households, municipalities, and industries.
