Abstract

Few works have assessed the water toxicity caused by leachate from urban landfills. The present study evaluated the superficial and groundwater quality around the urban landfill of São Carlos (SP), Brazil, using physical-chemistries analyses and acute and chronic toxicity with Ceriodaphnia silvestrii. In 2004, four water samples were collected during two fieldworks in the Galdino Stream (one site before and three after the landfill). The superficial water samples did not present any toxicity effect, while the well samples showed high values for some parameters and acute toxicity (p < 0.05) in all samples. In the first fieldwork, samples from the well before and after the landfill showed immobility of 50% and 100%, respectively. In the second fieldwork, samples from the well before the landfill caused immobility of 45% and presented chronic toxicity, while the wells after caused immobility of 100%. Thus, the results pointed out that the leachate is probably percolation and affecting the water quality of the groundwater.
