Serious question:

Given the mood alerting properties of lithium, are people living here chiller than would be expected (controlling for instance for poverty / SES) ?

My guess is that the presence of lithium in the groundwater is in trace amounts if at all, while the dosing of lithium is in the domain of ~300mg. A casual search for the quantity of lithium in brine from a mine shows a max of 1400ppm for a rich mine in Chile[1] so drinking straight brine wouldn't get you anywhere near the therapeutic dose. Good question!

1400 ppm is one part in 700, so you'd get your dose from one cup (250 ml) of that brine.

I agree it's not likely you'd get a measurable effect from the local groundwater.
