Abstract

Groundwater is considered as the main resources in most of arid and semi-arid areas; such as Libya, especially in the southern part where the only water resource is available is groundwater for all activities, agricultural activities the most important activity in the region. So that, the water quality evaluation for irrigation becomes more important. In this paper, water samples from several water wells in wadi Al-Shati were collected and analyzed. The results showed that, all the water samples classified as high salinity and low sodium, depending on U.S Salinity Laboratory Classification, which mean it have to be used carefully, even with a high soil infiltration rate. While FAO index classification showed different effects on soils from using this waters.
