Regarding the plastic in tap water : Professor dr. Colin Janssen, eco toxicologist at the University of Ghent, had the following to say (translated from Dutch) :
- That report is on a website (note: that would be Orb Media). It wasn’t a controlled report and hasn’t been evaluated by experts.
- Water is very hard to check because it’s very sensitive to contamination.
- There is no mention of how exactly these samples were taken and what precautions have been made when taking and handling the samples.
- Last year he himself checked a number of tap water samples and found absolutely nothing.
- Developed countries have drinking water stations whose filters can catch plastic fibres.
His conclusion : Most likely the samples in the report were simply contaminated by the people that collected them.

Note : if you plan to run that through a translator, keep in mind that “sample” and “steel” both translate to “staal” in Dutch. Not all translators will pick up on that though, so don’t be surprised if you read about people taking steels instead of samples.
