Abstract
World’s fresh water can be found as groundwater (29.9%) and surface water (0.3%) sources. The exploitable portion of these sources is about 200.000 km³ - 0.01% from the world’s water. The surface water resources generated in Brazil represent 11% from world resource. However, in order to consume water there must be some basic needs that have to be attended 0to0, some limitations in terms of its components. The Brazilian law responsible for water potability standards is Ordinance MS n° 518/2004 and CONAMA Resolution n° 357/2005. Thus, to know water characteristics is relevant to maintain good life quality. The State of Pernambuco has about 185 municipal districts, being 171 and the archipelago of Fernando de Noronha supplied with water by COMPESA. This paper aimed to identify and locate the springs used by COMPESA as water supply. GIS techniques allied to the attributes from those springs were used to compose thematic maps.
