A group of 12 young people in Groot Marico, near Zeerust in the North West , are calling on government to assist them with resources to do water monitoring in the Marico River.
They use indigenous methods, to determine if the water is safe for consumption by people and animals.
The Marico River forms part of the broader dolomitic aquifer system that feeds into the Limpopo River, providing water to people in South Africa, Botswana, Zimbabwe and Mozambique.
