Avaliação da qualidade da água para consumo humano de duas fontes subterrâneas de abastecimento no município de Lábrea/AM

Abstract

One of the greatest challenges faced by civil society is finding ways to preserve water sources free from contamination and suitable for human consumption. This difficulty is related to the contamination of groundwater due to urban expansion without proper planning, resulting in disordered land use and occupation. The present study aimed to evaluate the water quality of two wells located in the municipality of Lábrea, situated at the Federal Institute of Education, Science and Technology of Amazonas (IFAM). Two wells were selected: a) well 1, which is active and located within the Institute; b) well 2, which is inactive and located outside the Institute. To verify the physicochemical and microbiological parameters, the following parameters were analyzed: pH, Turbidity, Color, Thermotolerant Coliforms, Total Coliforms, Electrical Conductivity, Total Nitrogen, Total Phosphorus, Biochemical Oxygen Demand (BOD5), Dissolved Oxygen, and Total Dissolved Solids, comparing the results with the standards established by current legislation. Well 2, which is inactive and located outside, showed values of some parameters above the standards established by legislation. The deactivation of this well is considered an appropriate measure, as the results indicate that the water quality does not conform to established standards.
