May’s Mad About Micro spotlight connects Robert Koch’s legacy to modern water safety.
Koch helped prove that microorganisms can cause disease and that contaminated water can spread illness.
Today, that same scientific thinking lives on in standards like SANS 241, South Africa’s official drinking water quality standard.
With the latest shift from SANS 241:2015 to SANS 241:2025, the focus moves from testing and reacting to predicting and preventing, helping water providers identify risks earlier and protect public health more effectively.
