Análise e classificação das águas superficiais em área sob a influência de mineração de calcário

Abstract

The water quality is very variable and is directly related to the soil where it transits or is stored. The limestone mining activity is one of the oldest that exists being responsible for large local environmental impacts generation, among which the direct interference in water resources can be affirmed. Monitoring and management are important tools to protection, conservation and mitigating actions of the water resources. This study consists of surface water sampling in an occupied area by limestone mining, seeking the classification according the CONAMA Resolution 357/05, but also to analyze if the local activity generates influence under local water courses. The monitoring points are located in Caçapava do Sul/RS city. The study analyzed chemical, physical and microbiological parameters. With the results obtained it was possible to fit the Monitoring Points as classes 2 and 3, however, it was not possible to determine whether the activity is influencing the quality of surface waters.
