The quality of groundwater is determined in parts of Ramganga basin, Bareilly, UP, India. Spatial variation of all the major ions shows south-eastern increasing trend except chloride and sulphate. Groundwater in the area belongs to the Mg 2+ -Ca 2+ -HCO 3 − cation facies. The monsoonal rainfall changes the ionic abundance order from HCO 3 − >Cl − >NO 3 − >SO 4 −2 > F − and Mg 2+ > Ca 2+ > K + >Na + of pre-monsoon to HCO 3 − >Cl − > SO 4 −2 >NO 3 − >F − and Na + > Mg 2+ > Ca 2+ > K + of post-monsoon. Solute acquisition processes indicated that the rock weathering is the major mechanism of ions sources in groundwater. A coupled carbonate and silicate weathering type along with ion exchange processes are responsible for particular groundwater chemistry. Groundwater quality parameters were tested for drinking, irrigation and corrosion purposes. It is found that 8.5%, 26%, 49%, 14% and 3% of the samples fall under the excellent, good, poor, very poor and unsuitable category respectively. SAR, Na%, RSC and Kelly index suggests that groundwater is safe for irrigation purposes. But high TDS of few samples suggested the salinity hazard while using it for irrigation purposes. Low CR values indicated a lower degree of corrosion hazard to the underground metal pipelines in the area.

北方邦巴雷利区恒河中部平原 Ramganga 含水层的水化学特征、地下水质量和溶质来源

地下水的质量由印度北部巴雷利的 Ramganga 盆地的部分地区确定。除氯化物和硫酸盐外，所有主要离子的空间变化均呈东南增加趋势。该地区地下水属于Mg 2+ -Ca 2+ -HCO 3 - 阳离子相。季风降雨使离子丰度顺序从季风前的 HCO 3 − >Cl − >NO 3 − >SO 4 -2 > F − 和 Mg 2+ > Ca 2+ > K + >Na + 变为 HCO 3 − > Cl - > SO 4 -2 >NO 3 - >F - 和 Na + > Mg 2+ > Ca 2+ > K + 后季风。溶质获取过程表明岩石风化是地下水中离子源的主要机制。耦合的碳酸盐和硅酸盐风化类型以及离子交换过程负责特定的地下水化学。地下水水质参数进行了饮用水测试，灌溉和腐蚀目的。结果发现，8.5%、26%、49%、14%和3%的样本分别属于优秀、良好、差、非常差和不适合类别。SAR、Na%、RSC 和 Kelly 指数表明地下水可安全用于灌溉。但少数样品的高 TDS 表明将其用于灌溉目的时存在盐分危害。低 CR 值表明该地区地下金属管道的腐蚀危险程度较低。
