This investigation has been conducted to assess the suitability of ground water in Al-Kofra area - which located in South eastof Libya, for irrigation purposes and it is effect on some soil chemical properties.
To achieve this objectives, water samples from fifty wells were collected around Al-Kofra area. Water samples were analyzed for water quality criteria namely "EC, TDS, pH, soluble cations & anions, NO3 and boron. An additional assessment of usability of irrigation water was also used included determining "SAR, adj, SSP, RSC, Mg hazard, TH, pHc and PI" values.
Based on the results of chemical analysis of water wells samples, could be concluded that, all parameters were in suitable range, so ground wells water were suitable for irrigation purpose without any hazard, the results also showed thtat both SAR and RSC values were indicated no lability for salinity and sodicity hazard. In general, according to USSL, diagram, and FAO classification, majority of water wells samples fall within "C2-S1" classified, that indicated the water wells samples had low salinity and low sodicitylevels. and it could be successfully used for irrigation andsuitable for plant and soil.
