Quite fitting for Dutch researchers to compile such an overview. As the paper says: most PFAS tend to distribute & wash out of soil into waterways. NL surface water quality is among the poorest in EU member states.
However that has more to do with Netherlands' very intensive dairy industry. And to a lesser degree (but still important), other forms of livestock & agriculture. There's other factors, like dumps from illegal drug labs, wastewater treatment facilities unable to remove all remains of (prescription) drugs, the odd fire or spill from industrial plants, runoff from roads, etc etc. NL is a densely populated & industrious country.
In that context PFAS aren't high on the list of issues. But they are everywhere & persistent in the environment, which matters for production of drinking water (& not just that).
