Qualidade das águas do sabiá em função de seus usos: consumo humano e preservação de ambientes aquáticos em área de proteção permanente (APP)

Abstract

This study presents a diagnosis of water quality in the water courses present inside Parque Sabiá, in Uberlândia-MG, evaluating its suitability for different uses: human consumption and preservation of aquatic environments in a Permanent Protection Area (APP). Collections were carried out in three lagoons and a spring in this Park, in two different campaigns, with physical-chemical and microbiological analyses, in addition to collections in four water fountains. The results were evaluated in accordance with CONAMA Resolution 357/2005. The results were evaluated in accordance with CONAMA Resolution 357/2005 and Ordinance GM/MS No. 888/2021. In the drinking fountains, the pH presented values below the standard in the second collection (5.89 and 5.97). In Lagoa 2, the copper values detected (0.117 mg/L and 0.111 mg/L) were higher than expected, reinforcing the need for attention. Residual chlorine in all samples was within the limit (≥0.2 mg/L), and fecal coliforms were not detected. At the source, considering the classification as a special class for the preservation of aquatic environments, it presented parameters compatible with its classification. This diagnosis highlights the need for continuous monitoring and management measures to ensure water security and environmental balance.
