A comprehensive study was conducted from a semi-arid part of Yavtmal District, Maharashtra, India through combination approaches of geochemical modeling and its health consequences. The groundwater quality assessment shows that 55% of groundwater samples have the concentration of fluoride above the desirable limit. The high Na⁺/Ca⁺ ratio (>1.0) suggest the occurrence of cation exchange, which is further supported by Scholler’ chloro-alkaline indices. The geochemical modeling reveals that the existence of CaCO₃ precipitation and CaF₂ in groundwater. Simulation analysis indicates the dissolution of calcite, gypsum, and albite and precipitation of dolomite, fluorite, halite, and K-feldspar along with cation exchange as the main water–rock interactions influencing the groundwater chemistry. This is further significantly supported by pollution index of groundwater (PIG). PIG indicates about 18% of total samples fall in very high pollution zone, 3% in high pollution zone, 8% in moderate pollution zone, 24% in low pollution zone, and remaining (47%) express insignificant pollution. The 28% of subject studied have skeletal fluorosis varying from mild to severe type. In different pollution zones, the affected persons by dental fluorosis are varying from 15% to 41%. A proper monitoring and treatment are required for high fluoride water before its use for drinking and cooking.

通过地球化学模拟及其对健康的影响的综合方法，在印度马哈拉施特拉邦亚夫特马尔区的半干旱地区进行了全面研究。地下水质量评估表明，有55％的地下水样品中的氟化物浓度超过了理想限值。高的Na ⁺ / Ca ⁺比（> 1.0）表明发生了阳离子交换，这又得到了Scholler的氯碱指数的支持。地球化学模型表明，存在CaCO ₃沉淀和CaF ₂在地下水中。模拟分析表明方解石，石膏和钠长石的溶解以及白云石，萤石、,石和钾长石的沉淀以及阳离子交换是影响地下水化学的主要水-岩相互作用。地下水污染指数（PIG）进一步显着支持了这一点。PIG表示，约有18％的样本落在高污染区域，高污染区域占3％，中度污染区域占8％，低污染区域占24％，其余（47％）表示微不足道。28％的受试者患有轻度至重度氟中毒。在不同的污染区，氟中毒的患病率从15％到41％不等。高氟水用于饮用和烹饪之前，需要进行适当的监视和处理。
