Características hidrogeológicas e uso das águas do aquífero dunas/paleodunas na região de Paracuru-CE

Abstract

This work was the municipal Paracuru, Ceará where the study area (100km2) is located on the west coast of Ceará state, bordering with the municipalities of Paraipaba, São Gonçalo do Amarante and the Atlantic Ocean. Objective lye valuate the quality of groundwater and the situation of well construction. The methodology consisted do fliterature, registration of wells, development of thematic bases, steps fields, processing and integration of data and, finaily, the preparation of the report. .The implementation of the study in question is directed to the aquifer System Dunes/Paleodunes this extensively in Ceará coast .Associated with this important system are present also units of the Barreiras Formation and the fissure area composed off fractured rocks of the crystalline basement. The dunes and paleodunes constitute the geological units of greater aquifer Paracuru-Ce region. Obtaineda record of83wells in the municipal seat, 5 public and 78 private wells, tubular PVC or Amazon coated cement rins, From 83 registered well sin this study, we obtained an average of 9,52mdeep,theseactivewells in the area as follows:;3(3.5%)are moderately deep(20-50 m)and 78(94%) were considered shallow(<20m). 2(2.5%)well areno data on the depth. Regarding the use of water for irrigation, it was noted a high risk. It is recommended that existing wells in Paracuru-Ce County should be subject to assessment for recovery and monitoring purposes, to describe the condition and use of exploitation thereof.
