Dark colour= Shit water

Sewer treatment plants remove caffeine from the waste water so it won't damage wild life. If a body of water has a high caffeine concentration, that is a good indicator that the water is poluted. South Brazil has the most poluted water in the country, even though they have high HDI.

I don't even speak Spanish, let alone whatever language this is, and I can tell you it's a map of "nanograms of caffeine per liter of water." Apparently it is considered a contaminant? 2mg of caffeine in a liter of water is a high enough concentration to have a noticeable physical effect, I guess.

>high HDI.
Only SC, RS and PR are garbage

They are memeing, any spanish speaker can understand written portuguese perfectly fine.

Caffeine is a contaminant, but more than that it is a polution indicator since caffeine is supposed to be removed in sewer treatment plants.

Where does the caffeine come from? Manufacture of coffee products? Or directly from the urine of people who drank coffee?

Like, if the treatment systems are supposed to remove caffeine, why were they designed that way in the first place? Why is caffeine getting introduced into the water supply?

it's basically spanish, c'mon guys

Caffeine come from the human urine and the treatment plants remove caffeine during the process of removing other contaminants.

>Or directly from the urine of people who drank coffee?
I'm guessing this most of the chemicals we consume get pissed out.

So the most densely populated places (or more specifically the places with the highest number of people per volume of water, rather than people per unit area) would naturally have the highest concentration of caffeine in their water supply. Lower consumption of caffeine per capita (e.g. in underdeveloped non-coffee-producing areas with little outside trade activity) or higher degree of water processing would then decrease the caffeine levels you would predict from measuring population density.

South Brazil is densely populated and has a wealthier population who can conduct more trade, so I would expect it to have a higher concentration of caffeine in the water supply even if every state in Brazil had exactly the same water treatment protocols and facilities.

Not really, Rio de Janeiro and São Paulo are both wealthier and more densely populated, however they aren't nearly as bad as Porto Alegre or Curitiba. This isn't correlated..

always boil your water
don't trust the government

Boiling water kills bacteria but doesn't necessarily remove chemical contaminants. In fact, it may even increase the concentration of contaminants as clean water boils off leaving the chemicals behind in the pot.
