It'd be interesting to know how much chlorine, if any, is added to make the tap water potable. There are many places in the world where it's perfectly safe to drink the tap water, but not pleasant.

That's indeed interesting! Chlorine in the tap water seems to be one of the major factors why people buy bottled water, even though otherwise it might be perfectly healthy.

Hi HN! I made this while I was lockdown-bored. The data sources are linked on the website. I plan to add scientific reports on water-levels soon on a city-level. I want to raise awareness on how saving money and the environment often comes hand in hand when it comes to drinking water. For most people around the globe drinking straight tap water or using a water filter is a better solution than giving money to bottlin…

I think it would better to provide "No data" for French Guiana?

Do you mean because of the contradictory data sources? (WHO saying mostly safe, CDC no, Numbeo 50%)?

https://www.iswatersafetodrink.in/fiji LOL GTFO. This is nonsense.

Hey, can you tell me why? Don't know specifics about Fiji.

> The municipal water supply in Suva, Nadi and other large towns is chlorinated and can usually be trusted, but elsewhere avoid untreated tap water.

This is true everywhere in the world, is it not? What are you judging if not the municipal water supply?

Good point, thanks, I missed that! TBH I need to brush up on GDPR law. FYI The website itself is not using any cookies, but GA and the Crisp chat are using them.

I call bullshit omn that map. The water in the us tastes like cholrine and is better rated than the one in germany and bosnia, which both don't have that. Also the water is not adviced to be drank from tap in portugal where i was recently, and it is rated with 80?!?!?

Something like this is interesting, but I find it's missing a lot of the info that I care about. For example, here in Denmark, because our underground is chalk instead of rock, our water has high amounts of calcium - this makes the water 'hard', which means we can rinse off soap very easily in the shower, but most of our water-appliances and coffee machines struggle with limescale, and towels need to be washed with a lot of fabric softener or they will come out kinda stiff and scratchy. I'm sure there are other local concerns such as this (e.g. chlorine levels) that would be nice to look up.

Taking 'hard' water for granted since I was born, it's quite surprising and interesting that water cannot rinse off the soap.

This year I went abroad for a business trip. In the hotel, after washing my hands or taking showers, I found I couldn't rinse off the soap. I was so confused because it was so hard to do it, plus I brought my own soap. I inspected, smelled, and tasted the water carefully and didn't find any difference. In the end, I learned there is such a thing called 'hard' water.

I saw it now, it's an issue with the GeoJSON, I'll fix that soon!
