The present work had the aim to study the seasonal variation of the groundwater quality for irrigated at Lagoa de Salsa region in the district of Tibau (RN) during in the rainfall and drought season of 2008 and 2009. Sample water 24 were collected in aquifer distributed spatially in produced area in region at the two stationsalong. The variables electrical conductivity, Na, Ca, Mg, SAR, CO3, HCO3 and Cl were analyzed. The results showed that majority of the groundwater for irrigation in the Tibau microregion have use limitation. The concentrations for rain season was low in relation drought season, decreased salinity risk to mayoral parameters analyzed.
