While recent news of seawater containing above-safety levels of pollution has been received with shock, academic research has been saying the same for decades.

Seven years ago, Petrik et al (2017) found that, “the results of microbial tests for seawater and beach water samples are consistent with kayakers’ claims that on occasion the water is a health risk.”

In 2014, endocrinologist Edda Weidmann had similar findings, calling into question the Blue Flag accreditation system.

Petrik was interviewed in the False Bay Echo last year about the methodology of the Blue Flag accreditation testing, saying:

“Testing bimonthly for just enterococci is not an adequate safety measure in terms of health. There are many different disease-causing bacteria and viruses that do not get tested for. The wet sand or swash zones where children build sandcastles are not tested and these zones harbour higher numbers of bacteria. Moreover the sampling sites do not always correspond with the places where people swim. Furthermore the beaches and shoreline are contaminated with a very diverse range of sewage-related persistent chemical contaminants, which have a very adverse impact upon marine biota in the form of chronic toxicity and point to poor cleanliness and persistent environmental damage.”
