Avaliação do estado de conservação de nascentes vinculadas a projeto de revitalização no município de Mata Grande - AL

Abstract

Currently, society has increased its concern with environmental issues and with the availability and quality of water resources. Although Brazil is a hydric rich country, it is not uncommon for water scarcity triggered by prolonged periods of drought or by poor management of resources and practices that contaminate water sources. In that context, the present work sought to evaluate the conservation status of springs located in rural areas of the São Francisco river, as well as the characterization of the use of water present in them. The chosen springs are located in the municipality of Mata Grande, Alagoas, and were previously submitted to interventions by the Renascendo Project, a project that operates in the states of Alagoas and Pernambuco in the search for the revitalization and conservation of springs from a simple and sustainable methodology, through the soil-cement technique. Of the springs already recovered by the project in the municipality of Mata Grande, 4 of them were selected for the development of the present study. The parameters related to water quality were monitored through laboratory analysis available by the project, and the conservation parameters were observed on site. Five parameters were chosen for evaluation on the body and five parameters for evaluation around the springs, each parameter received a score between 0 and 3 according to its conservation status. From that, the scores were added and the result classified them as bad, regular or good conservation conditions. The results of the assessments on the springs' bodies revealed that 3 of them are in good condition, but, 1 is in regular condition and none was rated as poor. As for the assessments in their surroundings, 3 of them are in regular condition, while only 1 of them is in good condition and none was classified as poor. As for the use of springs, in 3, the main uses used were domestic, predominantly, for drinking and cooking, none of them were intended for agriculture or leisure.
