WATER QUALITY AND POTENTIAL OF DAMPING IN DAMS WITH THE INFLUENCE OF DIFFERENT SOIL USES

Abstract

Poor land use and an inadequate occupation close to the sources and absence of the Permanent Preservation Area (PPA) directly influence the quality and quantity of water in a river basin. The present work had as objective an evaluation of the physical-chemical quality of the water and potential of assertion by different influences of land uses in the municipality of Rio Verde, Goiás. Six water samples were collected in each dam, three of them without rainy period and three without estimation period, as samples were collected upstream and upstream of the dams. The parameters of pH, electrical conductivity (EC), total hardness (HT), alkalinity (A), turbidity (TB) and total solids (TS). In the rainy season the analyzed parameters obtained concentrations greater than the period of estimation of the product of solid particles for the source that contributes diminishing of the quality and quantity of the water. There was a greater degradation of the physical-chemical quality in basin 4 with use and occupation of exposed urbanization/soil, due to the clandestine launch of sewage, besides being a basin has greater potential of silting in approximately 22 years is represented by a total of silted.
