Today I wanted to look up the water quality at a destination I will be spending a day during the current massive heatwave. Luckily the European Environment Agency (EAA) publishes quite extensive data on bathing water quality in the whole EU. But I didn’t find a good dashboard like for example for the Austrian data reported to the same system or a map. But the data from the EAA can be downloaded from their website, so why not make a quick map myself.
