Abstract

Background: Chintamani village, Chikkaballapura district, Karnataka, India was found to possess high aquifer uranium concentrations. Geologically, Chintamani village is located on bedrock that is rich in elements like potassium (K) that naturally contain high levels of radioactive elements, such as uranium and thorium, due to the presence of alkali-feldspar granites and gneisses. Aquifer depletion has caused the concentration of these elements in groundwater to increase over time, posing a potential health hazard to the residents of Chintamani village.

Methods: Here, we report the sampling of groundwater from 12 borewells located in Chintamani village in between the period of August 2024 to December 2024. We observed groundwater uranium concentrations of 0.018 ppm to 8.64 ppm. Data for borewell depth, the quantity of total dissolved solids (TDS), and the elemental composition of TDS is also reported. We observed a statistically significant spatial distribution of uranium concentrations in Chintamani village. Borewells possessing the highest observed concentrations of uranium were clustered towards the northwestern region of the village.

Conclusions: This dataset is expected to serve as a resource for guiding potential remediation efforts in these locations.

印度卡纳塔克邦Chintamani村地下水铀的分布。

背景：印度卡纳塔克邦Chikkaballapura区的Chintamani村被发现拥有高含水层铀浓度。从地质学上讲，Chintamani村位于基岩上，富含钾(K)等元素，由于存在碱长石花岗岩和片麻岩，天然含有高水平的放射性元素，如铀和钍。含水层枯竭导致地下水中这些元素的浓度随着时间的推移而增加，对Chintamani村居民的健康构成潜在危害。方法：在2024年8月至2024年12月期间，我们报告了位于Chintamani村的12口井的地下水采样。我们观察到地下水铀浓度为0.018 ppm至8.64 ppm。还报道了井深、总溶解固体（TDS）含量和TDS元素组成的数据。我们观察到Chintamani村铀浓度的空间分布具有统计学意义。观测到的铀浓度最高的井集中在村庄的西北部。结论：该数据集有望作为指导这些地点潜在补救工作的资源。
