Land use and Occupation and Water Quality of the Meia Ponte River

Purpose: The present study aimed to study the catchment basin of the Meia Ponte River, analyzing land use and occupation, verifying whether permanent preservation areas are being preserved and which activities predominate in the region. Theoretical framework: Inadequate land use and the release of effluents can harm the quality and quantity of water available for use. Therefore, the sustainable exploitation of natural resources is necessary, combining economic development and environmental preservation. Methods: Physicochemical analyzes were carried out, evaluating the following parameters: pH, turbidity, color, temperature, biochemical oxygen demand (COD) and total phosphorus. The location chosen to carry out the collections was the water collection point for public supply from the Meia Ponte River. In addition to data obtained by the mapbiomas program using QGIS software. To delimit the basin, data from the Goiás geographic information system (SIEG) was used. Results and conclusion: The results showed that more than 60% of the basin area studied was pasture area, showing that there is degradation in the basin and satellite images showed that there are also areas of APP that are not properly preserved. Furthermore, water collections during the rainy season showed a high turbidity value, indicating that solids are being transported into the water body. Research implications: The main contributions are related to the eutrophication process and the environmental impacts caused by human actions. Originality/value: Verification of the impacts of human actions on land use and occupation on water quality in the Meia Ponte river region.
