“The country with the best water quality overall was Cyprus, with 100% of its waters being classified as excellent. This is followed by Greece (97.1%), Bulgaria (96.9%) and Austria (96.5%).”

Save you the click.

For everyone wondering, the country that coordinated what time and location to shit in the river to maximize the number of turds the mayor swam with when he sceduled his swim to prove the water was fine for the Olympics is third last.

And the report itself with an interactive map

These water bodies are more susceptible to short-term pollution events linked to heavy rainfall or drought, particularly during summer.

Pretty much all of Europe is going to have combined sewers somewhere. If you have combined sewers, you're gonna have raw sewage in your waterways if you get enough rain.

https://en.wikipedia.org/wiki/Combined_sewer

Combined sewers can cause serious water pollution problems during combined sewer overflow (CSO) events when combined sewage and surface runoff flows exceed the capacity of the sewage treatment plant, or of the maximum flow rate of the system which transmits the combined sources. In instances where exceptionally high surface runoff occurs (such as large rainstorms), the load on individual tributary branches of the sewer system may cause a back-up to a point where raw sewage flows out of input sources such as toilets, causing inhabited buildings to be flooded with a toxic sewage-runoff mixture, incurring costs for cleanup and repair. When combined sewer systems experience these higher than normal throughputs, relief systems cause discharges containing human and industrial waste to flow into rivers, streams, or other bodies of water.

It's expensive to replace those, so I'd expect them to be around to some extent until sewer systems need to be replaced.

Next: which country pollutes the most water? We in the Netherlands get all de sht that other countries dumb into the rivers

The gap between Estonia and all its neighbors 😬

I'm surprised the Nordics don't rank higher.

I still wonder how safe the Black Sea is considering how much radiation Chornobyl dumped into the atmosphere.

Maybe enough of it sank to the bottom.
