Gauteng residents need not be alarmed by reports circulating on social media regarding cyanobacteria or blue-green algae in the province’s waterways, specifically the Hennops River, Sesymylspruit, Rietvlei dam and Hartbeespoort dam.
Following rigorous engagement with experts on the subject matter, the Democratic Alliance (DA) in Gauteng can confirm that cyanobacteria is a natural component of river ecosystems and does not inherently pose the risks suggested in recent social media posts.
The presence of cyanobacteria in our waterways is a natural occurrence and part of healthy aquatic ecosystems. These photosynthetic bacteria play crucial roles in oxygen production, nitrogen fixation and the creation of beneficial relationships with aquatic plants.
While we understand public concern about water quality, the recent characterisation of cyanobacteria as a severe threat has been unnecessarily alarmist. The DA will continue to monitor water quality throughout Gauteng’s water systems, ensuring public safety remains our top priority.
We encourage residents to rely on official communications regarding water quality rather than unverified social media reports. The DA remains committed to transparency and will continue to monitor and report on water quality issues affecting our communities.
