Descrição: dc.descriptionWater bodies are containers that receive a large load of water quality variables through the release of domestic, industrial, and agricultural efuents. With this focus, this work aimed to conduct a temporal-spatial variability study in the Rio de Ondas Hydrographic Basin through multivariate statistical analysis. For this, seventeen collection sites were established in four stations along the Rio de Ondas and its tributaries between 2017 and 2018. Ionic chromatography with suppressed conductivity was used for ions determination, while ICP-OES determined metals’ total concentrations. The land use and occupation assessment between 1985 and 2021 was using data from MapBiomas were used andthe descriptive and multivariate analysis of the data using version free of the Statistica software. The results showed that, in 30 years, there was a growth of 569% of agricultural activities in the watershed area, with signifcant suppression of native vegetation, favoring the transport of contaminants to rivers. Ca2+, PO4 2−, Al, Cu, and Zn concentrations showed a statistically signifcant diference between the seasons, with higher medians in the rainy season. Rainy season infuenced the formation of three groups in the PCA, consisting of electrical conductivity, salinity, TDS, and PO4 2− (group 1); temperature, Fe, SO4 2−, and Cl− (group 2); and Ca2+, Mg2+, Na+, and HCO3 − (group 3). The strong correlation between parameters of each group indicates anthropic infuence on the watershed’s water quality. However, levels are within the potability standard.-
