Water resources are essential for environmental sustainability and socioeconomic development. However, the disorderly exploitation and contamination of water bodies have compromised the quality and availability of these resources. The methodology included analysis of satellite images via QGIS, evaluation of physical-chemical and microbiological parameters of the water, as well as verification of the presence of pesticides and heavy metals based on data from the Paraná Sanitation Company (SANEPAR) and the Information System for Monitoring Water Quality for Human Consumption (Sisagua). Objective: The objective of this study is to investigate insert specific research topic here, with the aim of briefly explain the main purpose of the research. Method: The methodology includes the characterization of the study area, characterization of land use and assessment of water quality. Results and Discussion: According to laboratory analyses, the water quality of Ribeirão Ema falls into Class I, according to Resolution No. 01/2019 of CBH-Piraponema. The water is suitable for public supply, with low levels of pollutants, meeting legal requirements. The presence of native vegetation in permanent preservation areas (APPs) and the absence of excessive pollution reinforce this classification. Final Considerations: The results showed that, although the collected water largely met the parameters established by environmental regulations, some issues of microbiological contamination, such as the presence of Escherichia coli, were observed in several collections. These results suggest that Ribeirão Ema is susceptible to fecal contamination, which may be related to the presence of large wild animals in the vicinity of the basin. The interaction of these animals with the aquatic environment, through feces and other organic waste, may be a significant factor in water contamination.
