South Africa’s sacred springs show microplastic pollution
Summary and headline written by AI from the source article. How we work
Environmental scientists in South Africa investigated nine sacred springs in the Eastern Cape and KwaZulu-Natal provinces and found microplastics in all of them.
The team examined these springs because they are culturally important sites but had not been scientifically assessed for pollution. Researchers detected a total of 184 microplastic particles, ranging from 5 to 48 particles per litre, though there is no established safe level for microplastics in drinking water.
The springs, including Isinuka near Port St Johns and sites in Mbizana and Bongwana, are naturally unique due to underground carbon dioxide escaping through the rocks. The research revealed that Isinuka Spring, a popular destination for healing and tourism, had the highest concentration of microplastics, with almost 70% of the particles being fibres likely from textiles.
While the scientists could not determine the source of the pollution, they noted the high number of visitors and potential for plastic waste to enter the water. Local communities expressed concern about pollution but also affirmed the springs’ importance for spiritual and physical well-being, with some emphasizing their responsibility to protect the sites for future generations. Researchers spoke with people collecting water and mud at Isinuka, and learned that many have used the water for years without experiencing health problems.
The scientists plan to continue monitoring the springs to determine the origin of the microplastics, how levels change over time, and if they accumulate in local wildlife. They emphasize the need for collaboration between scientists, government authorities, and communities to protect both the ecological health and cultural significance of these sacred water sources.
