The droughts that occur successively in the Northeast region, also reaching the littoral region and its systems of water supply, have significantly increased the groundwater use through wells. However, it is verified deficiencies of the hydrogeologic studies. The existing knowledge about aquifers, wells and its zones of protection is not still satisfactory to subsidize the efficient management of groundwater. Furthermore, it is verified the absence of specific national legislation, being present rules only in some states. The delimitation of zones of protection of wells is important to protect the systems of water supplying. The delimitation is one of the most efficient ways to protect the groundwater restricting the use of surrounding lands. In this work, the delimitation of the protection perimeters and the specific restriction zones of 30 wells used for public water supply in the urban zone of the city of João Pessoa, Paraíba, is done. The specific portuguese legislation was used as legal and theoretical reference. The perimeters had been delimited using a methodology of analytical base called method Calculated Fixed Ray, this, cited in the portuguese legislation. For better presentation of the results, a GIS (Geographic Information System) was elaborated including all the characteristics of the wells, as well as the established zones of protection.
