ABSTRACT
Throughout 45 years (1958-2003) the solid wastes from João Pessoa, state of Paraíba, Northeast Brazil, were disposed off in the former Roger's open dump, which is situated adjacent to the mangrove at the sides of Sanhauá river. Several environmental concerns results from this inadequate disposal of solid wastes, including the pollution of groundwater nearby the former Roger's open dump, which is the major point of investigation of this paper. Groundwater quality from 5 wells situated in the region of influence of the open dump were monitored from March 2006 until April 2009. Results have shown that the groundwater nearby the open dump cannot be drunk by the population without previous treatment, since it have presented some parameters of water quality in discordance with Brazilian legislation concerned to drinking water. Results have also shown that degree of pollution is higher in the wells closer to the open dump.
