PDFAbstract: This paper describes the evaluation of an aeration system located in the Bojórquez lagoon, Cancun, Mexico, a suction point and another at a distance of 300m discharge with a structure in the form of waterfalls by steps is presented. Three critical sites odours due to clandestine wastewater discharges were identified. Because Bojórquez is a touristic and protected area, it was not possible dredging as a method of remediation. When comparing the DO of the calculated against measured in the field, good agreement was obtained, with a saturation level of 6.3 mg/l in water to prevent the release of gases such as methane and hydrogen sulphide and nutrients such as phosphorus and nitrogen from the sediment to the water column.
