RESUMO:

The usage of groundwater resources has grown significantly in recent years. Due to its growing demand, the underground springs are subjects to environmental impacts, such as overexploitation and contamination. In an attempt to develop management strategies for groundwater resources conservation, an increasing number of studies related to the vulnerability of aquifers have been developed. In this context, the general aim of this work is to analyze the vulnerability of aquifers to contamination in the municipality of Catu, Bahia. The procedures for conducting this research were structured in the following stages: i) bibliographic survey and acquisition of secondary data; ii) spatial analysis and map making; and iii) analysis and interpretation of results. As the result of the modeling used by the DRASTIC method, 96.98% (419.78 Km2) of the aquifer areas observed in the municipality of Catu are classified as low vulnerability and 3.02% (13.09 Km2) as intermediate vulnerability. As the result through the GOD method has 74.22% (321.26 Km2) of the aquifer areas classified as vulnerable, 17.34% (75.07 Km2) as negligible vulnerability, 7.85% (33.99 Km2) as moderate vulnerability and 0.59% (2.54 Km2) as high vulnerability. As the result of the modeling used by the MAIA method, 77.17% (334 Km2) of the aquifer areas are classified as low vulnerability, 21.03% (91 Km2) as midium vulnerability, and 1.80% (7.8 Km2) as high vulnerability. The areas that present the highest levels of intrinsic vulnerability of the aquifers, when evaluating the results of the three methods individually, are located close to the Bom Viver and Duque de Caxias wells nearby the central region, to the north, next to the Coelho, Campo Grande and Mandacaru wells, and to the southeast, near to Mocambo I and Mocambo II wells.
