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 bottling companies like Nestlé!

I'd like to monetize this by either adding affiliate links to water filtration systems. Hope this helps! I think plastic pollution is one of our greatest challenges right now and I’d like to contribute to fixing that.

I've checked my city here is the link, https://www.iswatersafetodrink.in/Russia/Nizhny-Novgorod I don't know where 350$ is coming from. Most of the people here order drinking water in 20L bottles. Bottles are not thrown away, but collected and reused by water company. We spend about 150$/year*person on this, including delivery costs.

You are right, that's one thing I missed. Water bottle prices are determined on a country-level (I assume average bottle prices are higher in Moscow, I should show them ideally on a city-level) and I'm assuming people are buying 1.5L bottles for simplicity's sake. I am planning to provide a calculator soon to add more flexibility to the savings calculations.

I've lived in many places where the tap water is not safe to drink, and in all those places, nobody except tourists was buying 1.5L bottles of water.

In Germany, tap water has super high quality but people still buy 1 liter bottles, because fancy name or sparkling. I appreciate the pro-nature advertisement!

I think a city level would be great, and interesting. Looking at national numbers misses a lot. For example, Canada and the USA are very similar.

However, I live in Vancouver, and when I went to Chicago last year, the tap water was unbelievably bad (tasting). Even the complimentary bottled water in my hotel was bad.

Indeed, just looking at the data on a country-level misses a lot! I am working on providing city-level data, which by the way is substantially harder as the data for most places is hidden deep on some government websites as a PDF, sometimes outdated, sometimes not available at all!

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%)?

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

Looks fantastic! What mapping tool did you use?

It says "Leaflet" in the corner: https://leafletjs.com/

Yes Leaflet in combination with a CartoCDN basemap
