Residents of Groblersdal, Motetema and Tafelkop are urged to first boil the portable water they get from the tap before consuming it.
The Sekhukhune District Municipality says this will clear the high turbidity in the water that is coming from the Groblersdal Water Treatment Plant.
The Sekhukhune District Municipality says it is rectifying the matter.
According to US-based water treatment company, AOS Treatment Solutions, turbidity refers to how clear a liquid is.
Greater turbidity typically implies lower quality as it can cause heavy metals to be added to the water supply. It can shield bacteria or other organisms so that chlorine cannot disinfect the water as effectively.
Some organisms found in such water can cause symptoms such as nausea, cramps, and headaches.
