Results of the physical-chemical and microbiological analyses of the Brejo Alegre Stream at sampling points P1 and P2, from May 2021 to April 2022.

The table presents the results of the physical-chemical and microbiological analyses of the Brejo Alegre Stream, covering nine parameters at two sampling points (P1 and P2) over 12 months (May/2021 to April/2022). The dataset reveals the intense degradation of the stream, highlighted by BOD, Thermotolerant Coliforms, and Nutrients (Total Phosphorus and Total Nitrogen), whose concentrations frequently exceeded legal limits. It is important to note the presence of "Not Detected" (ND) values for Total Nitrogen in June and July 2021 at both points, which indicates a data loss or analysis failure for this specific parameter during that period, thus limiting the complete temporal analysis.
