Grades 7 and 10 students have identified testing sites and are having the water professionally tested to identify pollution levels.
Graeme Barnhoorn, of Sassenheim Estate, informed the schools about Effective Microorganisms which naturally treat pollution in rivers. The students were shown how to make the mud balls using EM liquid, pine bark and Oakhill clay. After 10 days, after the micro-organisms have multiplied, the balls were inserted into polluted areas. Follow-up tests will be conducted.
BioWise, Edge of Africa and the municipality are partners in the River Action Project.
