Avaliação preliminar da qualidade de água de poços tubulares em Cristalândia - Piauí

Abstract

Water quality is a crucial indicator of environmental health and sustainability. The reliance on tube wells for water supply is common in many regions, including Cristalândia-PI. This study investigated the water quality of tube wells located in the urban area of the municipality of Cristalândia-PI, through chemical, physical, and biological tests, aiming to provide an initial overview of the situation. Samples were collected in four neighborhoods: Novo Horizonte, Centro, Nova República, and Vila Zome, during the July and November campaigns, analyzing parameters such as pH, conductivity, turbidity, temperature, dissolved oxygen, and the presence of coliforms. The results revealed considerable variability in pH values, indicating different chemical conditions. Turbidity, in general, was within standards, but the presence of thermotolerant coliforms in several samples indicated fecal contamination, probably due to deficiencies in basic sanitation. Water temperature also showed variations, which may influence the proliferation of microorganisms. It is concluded that the water quality in the analyzed wells is heterogeneous, with emphasis on microbiological contamination. The implementation of measures to improve basic sanitation and continuous monitoring of water quality are recommended, aiming to guarantee the health of the population and the sustainable development of the region
