Abstract
In 1984, in Taubaté County, Brazil, a study was carried out to identify the groundwater pollution due to land disposal of chemical industrial wastewater. After characterization of the wastes, some analytical parameters were selected for a monitoring programme: TOC, COD and electrical conductivity. This programme was started after a network of 39 monitoring wells was installed. The water level was determined monthly and four times a year samples from the groundwater were collected for chemical analysis. The data were interpreted by a computer program (SYMAP) which produced hydrochemical and isopotential maps. The interpretation of these maps shows groundwater pollution due to wastewater infiltration and the limit of the pollution plume was the adjoining stream. In addition to determining the horizontal trend of pollution into the aquifer, research is necessary to verify vertical pollution, in order to evaluate the degree the aquifer has been compromised.
