Diagnóstico geoambiental do manancial Santa Luzia em Gilbuéis-PI

Abstract

Geoenvironmental diagnosis helps to understand the dynamics of ecosystems and predict possible impacts caused by human activities. The study was carried out in the city of Gilbués, in the state of Piauí, a location characterized by its difficult accessibility and little exploration, and with significant potential for environmental research, especially related to conservation and water quality. Initially, a survey and analysis of bibliographic sources was carried out, identifying existing gaps in knowledge and establishing a scientific context for the study. The next phase focused on collecting data in the field, with visits to the study area to directly observe local conditions, infrastructure and possible sources of pollution. Photographic records were taken to accurately document the observations. At the same time, a qualitative survey was carried out using spreadsheets, organizing and analyzing the data collected to identify patterns and trends. A central aspect of the research involved laboratory analyses, where collected samples were subjected to tests to evaluate water quality parameters, such as turbidity and the presence of coliforms. These analyzes offered deep insights into the health of aquatic ecosystems and potential risks to human health, allowing for an accurate assessment of the degree of pollution and the main sources of contamination. With this study, therefore, a comprehensive diagnosis of the water source was concluded, where, through laboratory analysis, it was found that the limit of coliforms was exceeded in accordance with the standards of Conama Resolution No. 274 of 2000, indicating a large fecal contamination. posing a risk to human health
