I would venture to say that the country in South America that has the least amount of disposable water would be probably in northern Chile which is a desert ie the Atacama desert which stretches from the Pacific across to the Andes Mts while on the other hand, in southern Chile there is a temperate climate with significant rainfall and considerable disposable water.
I think it may be the Great Basin Desert.
