A comparative study of Strontium (Sr) and Barium (Ba) along with associated major ions of groundwater was made from the Southern Mor Range, Balochistan, where both igneous and sedimentary rocks are exposed. In the studied samples, Sr²⁺ varies from 237 to 6,723 with a mean of 1,688 μg/l, while Ba²⁺ ranged from 40 to 1,332 μg/l with a mean of 207 μg/l. TDS and Sr²⁺ displayed moderate positive, while Ba²⁺ showed a slight negative relation. Majority (80.85%) of the samples have existed in the narrow pH range (7.5–8.5). The impact of water-rock interaction is evidenced from the Gibbs diagram; showed influence of igneous and sedimentary rocks on the release of Sr²⁺ and Ba²⁺. It is also evidenced from molar ratio of Sr²⁺/Ca^2+, Mg²⁺/Ca²⁺, Na⁺/Cl⁻, Mg²⁺/Cl⁻ of the groundwater. Strontium possessed fairly high relative mobility (RM, av. 0.349) and mobility index (MI, av. 4.38), while RM (av. 0.003) and MI (av. 0.04) of Ba²⁺ was very low. The saturation indices (SI) plots barite vs. celestite, showed saturation of Ba, while Sr²⁺ ions are unsaturated. The low Ba²⁺/Sr²⁺ (av. 0.208) indicated the existence of aquifer in low elevation areas and the HCO₃⁻/Cl⁻ ratio (>1) demonstrated a short flow path and speedy flow. The suitability of groundwater was assessed for drinking purpose as per World Health Organization (WHO) and Expanded Programme on Immunization (EPI) guidelines and possible environmental issues were discussed.

对Bal（Sr）和钡（Ba）以及相关的地下水主要离子的比较研究是在Bal路支省的南部莫尔山脉进行的，火成岩和沉积岩都暴露在其中。在所研究的样品中，Sr ²⁺从237到6,723不等，平均值为1,688μg/ l，而Ba ²⁺在40到1,332μg/ l范围内，平均值为207μg / l。TDS和Sr ²⁺表现出中等程度的阳性，而Ba ²⁺表现出轻微的负相关。大部分（80.85％）样品存在于狭窄的pH范围（7.5–8.5）中。吉布斯图证明了水-岩相互作用的影响。表现出火成岩和沉积岩对Sr ²⁺和Ba ²⁺释放的影响。它也被选自Sr的摩尔比证明²⁺ /钙^2+，镁²⁺ /钙²⁺，钠⁺ /氯^- ，镁²⁺ /氯^-地下水。锶具有相当高的相对迁移率（RM，平均0.349）和迁移率指数（MI，平均4.38），而Ba ^2+的RM（平均0.003）和MI（平均0.04）非常低。饱和指数（SI）绘制重晶石与天青石的关系曲线，表明Ba处于饱和状态，而Sr ²⁺离子是不饱和的。低的Ba ²⁺ / SR ²⁺（AV 0.208）表明含水层在低海拔地区的存在和HCO ₃ ^- /氯⁻比率（> 1）显示出较短的流动路径和快速的流动。根据世界卫生组织（WHO）评估了地下水是否适合饮用，并讨论了扩大免疫规划（EPI）指南，并讨论了可能的环境问题。
