CT's desalinated water may have long-term health risks, scientists warn

Scientists in the Western Cape have warned of long-term health risks associated with drinking Cape Town's treated sea water.

Desalinated sea water still carries concentrated traces of contaminants and pollutants, according to scientific researchers from the University of the Western Cape (UWC).

UWC's Professor Leslie Petrik explains that effluent going into the ocean has a concentration of chemicals.

She also explains that the desalination intake pipes will be positioned very close to local marine sewage outfall pipes.

According to Prof Petrik, drinking such contaminated water can be linked to health risks such as feminization, cancer and mutagenicity.
