Abstract

This work had the objective of analyzing the environmental situation of the Permanent Preservation Areas (APPs) of the Corrente River in the urban perimeter of the city of Corrente, Piauí. Therefore, the main environmental impacts located in the study area were identified and analyzed. For this purpose, data were collected in the field through on-site visits, collecting data through geographic coordinates with the help of GPS navigation for subsequent mapping. Then, a rapid assessment protocol (PAR), specific to the city of Corrente, was composed and applied, with fifteen parameters, with real-time data evaluation. As for the parameters whose evaluations involved the water quality indexes, which were collected in the field and sent to the IFPI - Campus Corrente water and soil laboratory, to be analyzed. According to the results obtained, it was observed that the analyzed samples are in agreement with the legislation, and some are in disagreement. Therefore, it was concluded that the quality of the stretches in the urban area of the Corrente river are in poor environmental conditions according to CONAMA Resolution 357/2005.
