Groundwater quality in coast region, Piauí state, Brazil.

The water resource systems of the coastal region of the Piaui State, Brazil, are abundant and of high productivity, favoring the use of the underground water for several ends such as, human consumption, irrigation and local tourism. Problems caused by the inadequate handling of the soil and the utilization of unsafe wells, are some of the factors that contribute, directly or indirectly, to the maintenance of the environmental quality of these resources. This study aimed to obtain current information on the physical and chemical characteristics to evaluate the underground water quality in six locations of the coastal region. Samples of 54 public and private wells were collected during the 2004 and 2005 dry season. The results were interpolated in geographical information system (GIS). It was concluded that the north and east costal region were the ones that presented the highest salinity indexes, presenting great restrictions to human consumption and irrigation.
