A groundwater quality investigation has been carried out within Kasra-Nukhaib district (west Iraq), The physicochemical analyses of twenty-four groundwater samples collected from UmErdhuma-Tayarat Aquifer are used in the determination of groundwater assessment for various uses supported by standard limits for various purposes. Conceptual spatial hydrochemical bi-model was prepared for quantitative and qualitative interpretation. The hydrochemical results are correlated with the standard classifications to determine the hydrogeochemical phenomena for groundwater use. The sodium percent of the groundwater samples on the Wilcox diagram indicates that the Groundwater is good to permissible quality for irrigation uses in the twenty-one percentile, of the samples, doubtful to unsuitable in sixty-seven percentile and unsuitable in twelve percentile. SAR values on Richards diagram show that 50% of the water samples are classified as admissible to good quality for irrigation. The other water samples are classified as bad to very bad. The results showed that the groundwater of the UmErdhuma-Tayarat aquifer has precedence for irrigation, agricultural purposes, animal drinking, and fair class for natural preserve activities, while the groundwater of the aquifer is not suggested for direct drinking purposes. In addition, the ground waters within the hydrogeologic system can be used in low-pressure boilers, mining, construction industry, and unsafe in high-pressure boilers. The Corrosivity ratio indicates that 75% of exploited groundwater from boreholes is unsafe for long-distance transportation through metallic pipelines.
