Abstract

Groundwater quality assessment is crucial for safe drinking water, especially in fluoride-affected regions. This study examines the spatial variability of groundwater fluoride concentration in the Bargarh Block of Bargarh District, western Odisha, during the pre-monsoon season. A total of 45 groundwater samples were collected and analyzed, revealing fluoride concentrations ranged from 0.20 to 3.35 mg/L, with a mean of 1.51 mg/L. Geostatistical interpolation using Ordinary Kriging was performed with spherical, exponential, and Gaussian semivariogram models. The best-fit model for accurate spatial prediction was identified. The Spherical model performed best, giving the lowest root mean square error (RMSE = 0.647). Using this model, about 175.42 km² of the study area was identified with fluoride levels exceeding the World Health Organization’s safe limit of 1.5 mg/L. This study identified hotspot zones of fluoride contamination and offers valuable input for groundwater management and public health planning.

印度西奥里萨邦氟化物易发地区季风前地下水氟化物含量预测的比较半变差模型方法

地下水质量评价对安全饮用水至关重要，特别是在受氟化物影响的地区。本研究考察了奥里萨邦西部Bargarh区的Bargarh地块在季风前季节地下水氟化物浓度的空间变异性。共采集45份地下水样本进行分析，氟化物浓度范围为0.20 ~ 3.35 mg/L，平均值为1.51 mg/L。利用普通克里格进行了球面、指数和高斯半方差模型的地质统计插值。确定了最适合精确空间预测的模型。球面模型表现最好，给出最低的均方根误差（RMSE = 0.647）。利用该模型，约175.42平方公里的研究区域的氟化物含量超过了世界卫生组织规定的1.5毫克/升的安全限值。本研究确定了氟化物污染的热点区域，为地下水管理和公共卫生规划提供了宝贵的投入。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
