VidaNaPraia

The bay is a closed body of water with a very narrow neck to the sea, and lined by a heavily populated urban area, much of which has an inadequate or non-existent sewage system. Even in those neighborhoods that have some sort of sewage system flood during the frequent, regular heavy rains, and then the streets are running with raw sewage, which then runs into the bay or the sea. It's been polluted for decades. The showers on the popular swimming beaches that front the ocean have also been shown to be polluted, and the sand there has a high level of fecal colliform. Installing a functional sewage system for every neighborhood in the greater Rio area, to prevent further pollution of the bay and ocean would require a major and expensive infrastructure overhaul, a huge and widespread construction project. That was never a reality possible before the Olympics, no matter what anyone promised. So how do you clean up existing pollution when more is pouring in every hour?
But since little of that shows, and even less so to tourists, why not pour money into tarting up what you can, seems to be the local thinking?
And how long will the money funding the UPPs (police posts in poor communities) last after the Olympic tourists go home?
