Effect of watershed land use on water quality: a case study in Córrego da Olaria Basin, São Paulo State, Brazil

Abstract: The water quality is related to the hydrologic and limnologic properties of ground and surface water, and significant efforts have been made to monitor water sources to understand the effects of land use changes in agricultural areas, with significant socioeconomic activities. The objective of this study was to evaluate the qualitative aspects of surface water in subbasins related to land use. Samples were analyzed in terms of physical and chemical parameters on monthly discrete water quality sampling in four … Show more

“…In this study, the calculation of the ALPI considered the Trophic State Index for phosphorus-TSI (TP) and the Trophic State Index for chlorophyll a-TSI (Chl), modified by Lamparelli [18], established for lotic environments, according to the equations (Eqs. (2) and 3…”

“…Water quality is vital when it comes to determining how society uses and values aquatic environments associated with natural resources [1] and their monitoring provides empirical evidence to support decision-making on health and environmental issues [2]. Thus, water quality can be assessed through variables such as dissolved oxygen, temperature, pH, toxic substances (heavy metals, surfactants, and phenols) and others [3,4].…”

“…Kandungan sulfat yang tinggi banyak terdapat di wilayah pertanian dan permukiman (Fianko et al, 2009). Selain itu, penelitian lain menyebutkan bahwa sulfat terkait dengan praktik pertanian yang umumnya berasal dari kandungan pupuk kimiawi (Simedo et al, 2018).…”

“…Tingginya aktivitas pemupukan yang berasal dari pupuk kimia ZA (Zwavelzure Amonium) telah meningkatkan konsentrasi parameter sulfat di titik D, sekalipun masih memenuhi baku mutu air kelas 2. Sejalan dengan penelitian Simedo et al(2018) yang mengemukakan bahwa aktivitas pertanian yang intensif dengan penggunaan pupuk kimiawi telah meningkatkan konsentrasi parameter sulfat di badan air yang terbawa oleh limpasan permukaan. Sebaran status mutu air di DAS Cimanuk disajikan pada Gambar 3.…”

“…Portanto, ressalta-se que um monitoramento contínuo da qualidade da água e a quantificação das alterações ambientais são bons indicadores de falhas no manejo e uso do solo, e representam formas eficientes para minimizar os efeitos dos impactos negativos. Neste sentido, estudos têm sido direcionados à identificação dos usos do solo e sua relação com os parâmetros de qualidade da água (BERTOSSI et al, 2013;MARMONTEL;RODRIGUES, 2015;MACHADO et al, 2016;SIMEDO et al, 2018;RODRIGUES et al, 2019).…”
