A new report reveals that water pollution across Cape Town’s rivers, vleis and estuaries has been getting steadily worse for 40 years, except for a few years.
The 88-page Inland Water Quality Report summary, released on 9 February, shows worsening pollution except for a slight improvement between 2010 and 2015. In a footnote on page 22, the City warns that the rivers, vleis, and estuaries are so polluted that swimming is not recommended.
The coastal water quality report was released a year ago, and revealed widespread pollution of the marine environment. But this is the first inland water quality data made publicly available since the 2016 results contained in the 2018 State of the Environment Report. The latest data from 242 testing sites shows that many of our rivers, vleis, and estuaries have over time become so polluted that swimming or wading is not advised.
