Pollution problems

This compromises the communities who makes a living from the fishing on the lagoon.
This is not the only pollution problem surrounding Maceió. The Riacho Salgadinho is also the destination for most of the sewage system in Maceió downtown. In the past years, several politicians have made promises of putting sewage treatment stations to alleviate the problems caused by the pollution during the rainy season, but limited progress has been made.
