Objective: Analyze the surface water quality of the Santo Antônio stream in Santo Antônio do Tauá, in the state of Pará, based on the current environmental legislation of CONAMA nº 357, 274 and Ordinance GM/MS nº 888.   Theoretical Framework: The research uses contributions from the literature regarding normative guidelines on water quality standards essential for understanding and monitoring environmental conditions and related problems, through specific laws and regulations.   Method: This is an experimental, descriptive, cross-sectional study, with a qualitative-quantitative approach, developed from water samples from the study site. The microbiological and physicochemical analyzes were determined by the procedures and recommendations described in the Standard methods for the examination of water and wastewater (APHA).   Results and Discussion: The results proved that the physical-chemical and microbiological parameters of surface water are in accordance with the standards established in legislation regarding water classification and bathing (CONAMA nº 357 and 274), being in disagreement only with regard to potability standards (Portaria GM/MS nº 888), at one of the points of analysis.   Research Implications: The data and observations allowed a response to potential environmental problems, contributing to the quest to preserve water resources and serving as a model for other communities facing similar challenges.   Originality/Value: The study provides unprecedented data regarding the water quality of the Santo Antônio stream, identifying variations and trends that correlate with local environmental management.
