Qualidade das águas do Arroio das Lavras sob influência de atividade mineira

Abstract

The problem of water is increasingly evident throughout the world, revealing problems as much as quality as quantity. Its availability is increasingly reduced due to pollution processes, caused by mining activity, which compromise its use by the inadequacy of its quality. This work presents the analyzes in nine points of the study area with the objective of verifying the influence of the mining activity in the waters of Arroio das Lavras. Samples were collected from nine water samples taken from the stream in the city of Lavras do Sul. Biological characterizations were also performed, such as total coliforms, and physical and chemical characterizations such as pH, electrical conductivity, conductivity, turbidity, Alkalinity, hardness, x-rays and total chloride. The evaluation of the results was correlated with Resolution No. 357/2005 of CONAMA and with Ordinance No. 2914/11 of the Ministry of Health.
