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.

The present study examines the chemical properties of the groundwater in the Wadi Al-Mohammadi basin, which is located between the cities of Ramadi and Hit in the Upper Euphrates region. The study is conducted based on the field, geomorphological and geological study of the study area. The water quality of some wells in the region was monitored during 2017, for irrigation according to the FAO Standard and their classification according to Richards. The results of the laboratory analysis showed that all of the well water under study exceeded the criteria for use of irrigation. Therefore, it is not recommended to use it in the Wadi Al-Mohammadi basin because it is saline water, where the values of electrical conductivity, which is a factor affecting agricultural use, ranged between 3.68-7.51dS/m-1 for wells 7 and 5, respectively, while the SAR ratio ranged between 7.20 - 183.6 for wells 7 and 2, respectively. Wells (5,4,1), according to Richard's chart, 1954, were classified as C4-S2, medium and very high, and wells (2,6,3,7) C4-S4, C3-S3, C4-S3, C3-S1, respectively. With continuous use, salt accumulations are formed which eventually lead to salinization of the soil and increasing the state of the problem of desertification and conversion of agricultural lands from producing to unproductive lands. In the case of its use, the methods for accuracy management intentions and selection of soil types as well as cultivation and selection of plants resistant to salinity and reducing the state of degradation of those soils within the valley should be followed. This causes increasing crop productivity.
