Proposta para o enquadramento das águas subterrâneas na bacia sedimentar do baixo curso do rio Paraíba.

Abstract

In Brazil, the use of groundwater has increased in the recent decades,however to a lesser degree than the surface water. Groundwater is susceptible to contamination just as surface water, but once contaminated, dean up is much more complex and costly when compared with surface water. The National Water Resources Policy aims to protect water quality by managing the implementation of the framework of the instrument of water bodies. The research aims to study possible goals for the framework of bodies of water, of the Lower Basin of the Parafba River Course, specifically the most urbanized region, involving the cities of Cabedelo and Joao Pessoa, the capital. The proposed framework is done through analysis of the criteria set forth in resolutions CONAMA 396/08 and CNRH 91/08, but does not include all variables that should be considered. Criteria are proposed as complementary frameworks for the assessment of groundwater intrusion and interference between wells. In this study we simulated'all the criteria and the resolutions proposed for the study area. For this we classify water bodies. The confined aquifer and aquifer free was featured in class 3. The surface water bodies showed class 3 for a stretch of the Jaguaribe river and the Cabedelo creek, then class 4 to another part of Jaguaribe river and Cuia river. Through the actions suggested in this work, classes 1 and 2 have the designed framework goals possible to be achieved for groundwater. It was concluded that one of the causes of poor or inadequate implementation of the instrument framework of groundwater in the Brazilian states is due in large part to the complexity of its application.
