Pollution concerns mount as black sludge spills in Carletonville Industrial Area
It has triggered a pollution investigation by the Merafong Municipality and Gauteng environmental authorities.
Residents are concerned about environmental pollution after thick black sludge was again found streaming into the veld behind a local business.
During a recent visit by The Herald, the sludge was visibly flowing from the back of the facility in Kleim Street and had dammed up across a large area of grassland, creating a scene described by one resident as resembling a “wasteland.”
“One cannot even walk here. How long will it be before this starts to form a sinkhole?” a concerned local asked, pointing to the soggy, discoloured soil surrounding the site.
The Merafong City Local Municipality has confirmed that it is actively addressing the issue. According to the municipality’s marketing and communications manager, Temba Fezani, they have referred the matter to the Gauteng Department of Environment (GDE), which is handling it through its Section 24G sub-directorate. This division deals specifically with unlawful environmental activities and potential prosecution under the National Environmental Management Act (NEMA).
“The municipality is aware of the matter and has been in constant communication with GDE,” said Fezani.
Ongoing problem since 2019
This is not the first time the business has been in the spotlight. Since 2019, residents have complained about various forms of pollution emanating from the premises. In the past, the Merafong Fire Department even shut down the facility temporarily due to air pollution violations.
Despite these interventions, community members say little has changed. “This has been going on for years. The authorities must take stronger action before there is permanent environmental damage or even danger to public health,” said another resident.
Environmental and structural risks
The presence of thick, oil-like sludge in the area raises concerns not only about soil and water contamination, but also the potential for sinkhole formation — a serious issue in Carletonville, which sits on dolomitic ground known for its vulnerability.
Authorities have yet to confirm whether any formal enforcement actions or cleanup orders have been issued. Meanwhile, residents remain frustrated and fearful that inaction could lead to irreversible damage.
