AVALIAÇÃO DE EUTROFIZAÇÃO NO RIO SÃO JOSÉ PARA FINS DE ABASTECIMENTO DE ÁGUA

This article aimed to evaluate the eutrophication of water from the São José River, downstream of the effluent discharge from a sewage treatment station, by calculating the Trophic State Index. For this calculation, the parameters chlorophyll a and total phosphorus were used during the period from 2010 to 2014. Data from the parameters used for this research were obtained from the State Water Resources Agency. From the Trophic State Index values, water and the monitoring point wereclassified as ultraoligotrophic (EIT ≤ 47), oligotrophic (47
