The aquifers, especially those that occur in urban areas, are very susceptible to contamination or pollution due to the concentration of incompatible activities with the areas that should receive restriction on land use. The objective of this work was to analyze land use in the protected groundwater caption perimeter for the public supply in João Pessoa city (Brazil). From protection perimeters already defined, a study was made of the land use of internal areas through field visits, and observation of satellite image. The exercise of activities prohibited or constrained in the areas that should be protected was noted. The research demonstrated the need to regulate activities that potentially pollute the groundwater and contributes as a useful tool for building policies for the planning of activities on urban land.
