The quality of Amazonian water resources is very important for the maintenance of life and biodiversity in the biome. The advance of urbanization in northern Brazil increases the degradation of these resources, mainly due to the lack of basic sanitation in most cities. Santarém is a municipality located in the west of Pará, and in recent years is going through a period of urban expansion, which causes the degradation of underground and surface water resources, due to the disposal of effluents in natura in streams and the lack of information in the construction of septic tanks.This study assessed the seasonality of contaminants, such as nitrite/nitrate, phosphorus, phosphate and thermotolerant coliforms (E. Coli) and physical-chemical parameters, in the dry and rainy seasons, between 2018 and 2019, in 9 water samples, 6 of which were groundwater and 3 were surface water from communities surrounding the landfill in the city of Santarém. The results showed a difference between the dry and rainy seasons, the latter with the highest concentrations for contaminants. In one sample there was a 1520-fold increase in the rainy season compared to the dry season for E. Coli. Even so, for most parameters there is compliance with the Brazilian legislation CONAMA 357/05 and CONAMA 396/08. The differences in concentrations of contaminants in both seasons may be related to the lack of basic sanitation in the region, which imposes the construction of septic and black pits on residents. ; A qualidade dos recursos hídricos amazônicos é muito importante para a manutenção da vida e da biodiversidade do bioma.
