Water quality, land use and land cover: subsidies for water resources management in the Pindaré river watershed, Maranhão- Brazil

This study will discuss surface water quality through an analysis of the Pindar & eacute; river basin, located in the Amazon region of Maranh & atilde;o. To this end, water quality data was assessed at 13 collection points and correlated with land use. The water showed acceptable conditions in the parameters measured, with the exception of some points which showed high turbidity, considerable conductivity and a decrease in dissolved oxygen in areas located adjacent to urban centers, where there is an increase in the dumping of solid waste and in natura sewage into the spring. This research proposes discussions for improving and/or maintaining water quality, identifying the main uses in the face of primary and secondary contact with the population.
