Pollution problems
editThe natural environment of Mundaú Lagoon is affected by pollution problems, mainly due to urban sewage dispensing along its shore close to downtown Maceió.[2] This compromises the communities who makes a living from the fishing on the lagoon.[3]
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,[when?] 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.[4]
Recently a new threat has arisen to the ecosystem of the Mundaú lagoon, the mining of rock salt by Braskem company.[5][6]
