目前的研究重点是 Ambagarh chowki 地下水的水文地球化学。该研究的主要目的是评估饮用水和灌溉用水的水质，地下水的水文地球化学。为此目的，各种物理化学参数，如 pH 值、电导率 (EC)、总硬度 (TH)、氯化物 (Cl - )、氟化物 (F - )、钙 (Ca 2+ )、镁 (Mg 2+ )、钠 (分析了Na + )、钾 (K + )、碳酸氢盐 (HCO 3 - ) 和硫酸盐 (SO 4 2- )。地下水中主要的主要离子为阳离子Ca 2+ > Mg 2+ > Na+ > K +和作为阴离子，HCO 3 - > Cl - > SO 4 2- > F -。取样地下水的 pH 值范围从中性到碱性（7.0-8.8）。其中，除离子少外，地下水中各项分析参数均为安全饮用，碳酸氢盐含量也超过了不适宜饮用的允许限度。潜在的健康危害元素氟化物从 0.1 到 2.2 mg/l 不等，与 pH、Na +和 HCO 3 -呈正相关地下水中的含量。饮用水水质指数（WQI）在 12.22 和 185.56 之间波动，报告显示大部分地下水适合饮用，只有一个样品不适合饮用。通过评估钠吸附比（SAR）、渗透指数（PI）、凯利比（KR）、镁危害比（MHR）、钠百分比（%Na）、潜在盐度（PS）来评估该地区的灌溉水质, 和残留的碳酸钠 (RSC)。而除了PI（3.70%）、MHR（40.74%）、RSC（22.22%）和PS（7.41%）不适合连续灌溉外，大部分地下水良好且适合灌溉。使用相关性、Piper、Gibbs 和其他地球化学分析评估地下水的水文地球化学。Piper 三线性图反映了 Ca (Mg)-HCO3 -型水主要贡献了整个采样地下水的约 90%。地下水中的不同离子来源于矿物的硅酸盐和碳酸盐风化作用下的岩水相互作用。

Hydrogeochemistry and groundwater quality assessment in Ambagarh Chowki, Chhattisgarh, India
The current study was focused on hydrogeochemistry of Ambagarh chowki groundwater. The main aim of the study was to evaluate the water quality for drinking and irrigation uses, hydrogeochemistry of groundwater. For this purpose, various physicochemical parameters like pH, electrical conductivity (EC), total hardness (TH), chloride (Cl−), fluoride (F−), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), bicarbonate (HCO3−), and sulfate (SO42−) were analyzed. The major dominating ions in groundwater was found as cation Ca2+ > Mg2+ > Na+ > K+ and as anions in order of HCO3− > Cl− > SO42− > F−. The pH of sampled groundwater was ranged from neutral to alkaline in nature (7.0–8.8). Among, all-analyzed parameters in groundwater were safe for drinking purpose except few ions and bicarbonate content was also exceeding the permissible limit which was not suitable for drinking purpose. The potential health hazard element fluoride was varied from 0.1 to 2.2 mg/l and positively associated with the pH, Na+, and HCO3− content in groundwater. The drinking water quality index (WQI) was fluctuated between 12.22 and 185.56 and reported that most of the groundwater was suitable for drinking purpose except only one sample was unsuitable for drinking. Irrigation water quality assessment of the area was performed by evaluating as sodium adsorption ratio (SAR), permeability index (PI), Kelly ratio (KR), magnesium hazard ratio (MHR), percent sodium (%Na), potential salinity (PS), and residual sodium carbonate (RSC). Whereas most of the groundwater were good and suitable for irrigation use excluding PI (3.70%), MHR (40.74%), RSC (22.22%) and PS (7.41%) were unsuitable for continuous irrigation. Hydrogeochemistry of groundwater evaluated with correlation, Piper, Gibbs, and other geochemical analysis. The Piper trilinear diagram reflects the Ca (Mg)-HCO3− type water was mainly contributed approximately 90% of entire sampled groundwater. The different ions in groundwater were originated from the rock water interaction through silicate and carbonate weathering of minerals.
