In Lyon the air is full of PFAs, unless you breath bottled air you are screwed.

@Scarlet,
Why resorts? Because this is a ski site.
Back when I started skiing in the 1980s the advice was not to drink tap water in ski resorts.

@Kenzie, wasn't that just what all Brits believed about "foreign" water? I recall being told not to drink the water in Spain, France, Italy etc. From recollection, Switzerland was ok.

@ousekjarr, interesting article. I was intrigued by the comment in the article that said "For those who do still want to avoid PFAS exposure, the researchers had some good news: they can mostly be removed using simple household solutions. For example, boiling or passing the water through an activated carbon filter jug can reduce levels by up to 90 percent." ""Our findings highlight the widespread presence of PFAS in drinking water and the effectiveness of simple treatment methods to reduce their levels," Harrad said. "Either using a simple water filtration jug or boiling the water removes a substantial proportion of these substances."
I can understand how using a charcoal filter could reduce the concentration level, but was puzzled by how boiling could achieve that. A quick internet search came up with this AI overview:
Boiling water does not remove PFAS (per- and polyfluoroalkyl substances) and can, in fact, increase their concentration in the remaining water. PFAS are very stable compounds that don't break down with heat, and boiling just causes the water to evaporate, leaving behind a higher concentration of PFAS in a smaller volume of water.
Here's why boiling doesn't work and what does:
PFAS are heat-resistant:
Unlike some contaminants that can be removed by boiling, PFAS are designed to be stable and resist breakdown from heat.
Concentration effect:
When water boils, it evaporates, but the PFAS remains. This means the concentration of PFAS in the remaining water increases, making it potentially more harmful.
If you don't trust AI there's plenty of reports that state boiling doesn't remove the PFAs, e.g https://www.health.state.mn.us/communities/environment/hazardous/topics/pfashometreat.html

@Alastair Pink, agreed - and charcoal filters are also somewhat dubious depending on the type and their lifecycle since a lot of people seem to think that they can continue using an old filter cartridge long after its specified life.
My point was that the original suggestion was flawed, and in some/most cases will be worse than drinking the tap water.

@ousekjarr, agreed - in general almost anything you do to tap water makes it worse than drinking it straight from the tap. Filtering, storing in the fridge, piping through plastic tubing into a water cooler, remove chlorine then letting the water stand, softening...

Yeah but it doesn't make any sense to suddenly stop drinking “resort” tap water in isolation due to PFAS. If you want to reduce exposure, change your habits at home, where you are for the majority of the year.
I believe most advice not to drink tap water in Europe was/is due to different/increased mineral content, which can cause GI issues in some people. Localised scandals aside, tap water and spring water is generally safe to drink.

Clearly it is. Since I was a child I have always called it Swiss as I know it is on Lake Geneva.... I am an idiot.

In the 1990s I attended an international conference on drinking water supply and recall an american professor who was advocating than only bottled water would be drunk by 2000 and no one would drink tap water due to the use of chlorine to disinfect the water. One of the side comments some other american presenters were saying was that the tap water in american ski resorts was particularly unsafe as it was only filtered glacial water rather than disinfected. Both were wrong. But in those days stomach upsets in USA ski resorts was actually quite common.

Did these "experts" indicate which American ski resorts had glacier-fed drinking water suppliers? I'm struggling to think of many (outside Mt Hood and Alyeska) that have any glaciers at all.

@snowdave, OK, it was probably snow melt and mountain streams they were talking about as I recall Colorardo being mentioned. It was a particular microbe they were discussing. TBH I wasn't particularly interested in the water quality papers, but learnt a lot about alternatve treatment methods. (chlorine was still the best)

This is why I drink bottled water abroad. Foreign water doesn’t agree with me.

Of course the different mineral content in the water varies just as much across the UK. Examples include the very soft water in Birmingham with its slightly brown tinge due to being sourced from the Welsh moorland; the concentration of beer brewing in areas such as Burton upon Trent with the gypsum beds nearby; the very hard water in some area due to the predominant water source being aquifers and of course the worrying high levels of nitrates in the water supply of East Anglia due to the intensive use of agricultural fertiliser. However all tap water in the UK is subject to the same guidance as the rest of Europe. The levels are no higher or lower. (There are of cause exceptions such as the Greek Island of Kalymnos where drinking water is obtained from tanks scattered around the island and the taps supply sea water)
Bottled water is often sold on its taste and in many cases has a mineral content higher than would be permitted in drinking water. In some cases you actually pay a premium for bottled tap water; Peckham Spring springs to mind (wasn't that sold by Coca Cola)

I thought the reason bottled water was recommended back in the 70s/80s Europe was because we assumed much of Europe was practically 3rd world

In Southern France and Spain there was a cholera risk at one time.
A lot of French tap water, and Evian, is contaminated by chlorothalonil, a fungicide. I think Evian are able to filter for this now.

What was amusing at the time was that people would very carefully avoid the tap water but then demand ice ( made from tap water) in their drinks.

Val d'Isère had a reputation for terrible tap water about 15-20 years ago but I have no idea if it was substantiated or not. Safer to stick to wine

I was always told that the tap water was safe but to avoid ice in drinks at all costs. I still do.
