Abstract


In Lapus River, the persistence of contaminants depends on the degree of physical, chemical and biological post-storage rehabilitation, and the geomorphology of the water course, being relatively high. The collected sediments have changed their coloration according to the nature of the gray-brown to brownish-brown impact, and in the sections immediately downstream of the surface contamination sources, a finely coat of colloidal suspensions (flocs) formed following the reaction chemical neutralizing pH. Average concentrations were recorded for Ni in section 2 downstream of mine water discharging into the Lapus River, the trend of contamination being transferred to section 4. The assessment of the level of sediment contamination was made in correlation with aspects related to alluvial transport, hydrology and the morphology of evil.
