【 摘 要 】

A detailed study of the physical-chemical and bacteriological qualities of the subterranean water at sanitary landfills in the Metropolitan Region of Londrina (PR), was carried out. The field of twelve wells that reach the groundwater as well as the emergence of the watertable of the Periquitos River, were also monitored. The results of the analyses of 120 samples of the collected water were compared to the permissible maximum values for human consumption according to the Federal Legislation in Brazil. Total excrements were found around 3,1 NMP/100mL (Well 4) and 120330 NMP/100mL (Periquitos River) and fecal matter between 0 and 4100 NMP/100mL (Periquitos River). Such values were associated to the contamination caused by the presence of animals from neighbor properties, feeding themselves in that region. The pH, turbidity, COD and BOD were among the values expected, except for the conductivity that showed to be altered.
