Groundwater contamination by fluoride is a typical problem associated with most of the regions in India. Mining of minerals can accelerate the dissolution of fluoride resulting in the further contamination of groundwater resources. The present study was undertaken to determine the concentration of fluoride in groundwater around the Bakhrija sandstone mine located in Haryana state, India. It was observed that the groundwater in immediate vicinity of the mine had relatively higher level of dissolved fluoride. The risk associated with consumption of fluoride contaminated groundwater was also observed to be higher in villages adjacent to the mines. The geochemical investigation suggested that dissolution of carbonate minerals may have resulted in solubilisation of fluoride in groundwater through the process of ion-exchange. The study concluded that fluoride level may rise in the other nearby regions if the intensity of mining increases. It may result in further spread of fluoride to other aquifers located around Bakhrija mine, if suitable environmental management plan is not developed.

氟化物对地下水的污染是印度大多数地区的典型问题。矿物的开采会加速氟化物的溶解，从而进一步污染地下水资源。进行本研究是为了确定印度哈里亚纳邦Bakhrija砂岩矿周围地下水中的氟化物浓度。据观察，紧邻矿山的地下水中溶解的氟化物含量相对较高。在矿山附近的村庄，与消耗氟化物污染的地下水有关的风险也更高。地球化学研究表明，碳酸盐矿物的溶解可能通过离子交换过程导致了氟化物在地下水中的溶解。研究得出的结论是，如果采矿强度增加，附近其他地区的氟化物含量可能会上升。如果没有制定适当的环境管理计划，它可能导致氟化物进一步扩散到位于Bakhrija矿周围的其他含水层。
