Effect of the decommissioned Roger open dump, João Pessoa, Brazil, on local groundwater quality
AbstractThroughout 45 years (1958-2003) the solid wastes from João Pessoa were disposed off in the former Roger’s open dump, which is situated adjacent to the mangrove at the sides of Sanhauá river, intensifying environmental problems and threatening the health of people living nearby. Between 1999 and 2003 the decommissioned open dump received wastes from the cities of Cabedelo and Bayeux. Several environmental impacts result 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. The water quality of 6 wells situated in the region of influence of the open dump were monitored. Results have shown that the groundwater near the open dump cannot be drunk by the population without previous treatment, since it has some parameters of water quality in discordance with Brazilian legislation concerned with drinking water. Results have also shown that the level of pollution is higher in the wells closer to the open dump.
