Research reveals troubling state of the Vaal River
The Vaal River – one of the most important water sources in South Africa – is currently “surviving but not thriving”, according to North-West University (NWU) researcher Prof. Wynand Malherbe, who is studying the ecological health of the river in the Vredefort Dome area.
Although the river continues to sustain aquatic life, increasing levels of pollution are placing severe pressure on the ecosystem.
The phrase “surviving but not thriving”, originally coined by a journalist from the Parys Gazette, captures the delicate state of the river, Prof. Malherbe explains.
