Avaliação quantitativa de poços na cidade de Campina Grande - PB.

Abstract

The hydric crisis in Campina Grande­PB has grown the number of drills of wells, not gratuity, because of the longtime of water rationing. The wells get water from crystalline fissure, because the geology of the region is almost all of crystalline rock and with the crisis that source of water has increased. Beyond that, the objective of this job was to evaluate the quantity of wells in the urban area of Campina Grande, and distribution of wells in the space and the parameters of flow and deep. To do that, we got all the physical and socioeconomics characteristics of the region, and the data of wells were collected within the government and companies. The information was obtained, specialized and putted in the SIG software, and statistically analyzed, checking the correlation and frequencies. With 72 wells, we discovered that bigger flows appeared near the geologic fissures/shear zones appointed in the map of CPRM, still need more investigation. The results shown that the wells have 1,43m3/h of average flow and are relatively helpful in times of crisis, but the production in the region are relatively low, compared with other averages, like São Paulo and other northwesters states.
