“…Within soils, pH controls the mobility of contaminants such as arsenic and fluoride. As soils become acidic, fluoride mobility increases allowing concentrations to increase [24]. Alternatively, as pH shifts becoming alkaline, arsenic mobility increases, resulting in elevated concentrations [25].…”

“…The presence of fluorides in groundwater is most frequently associated with weathering, where water passing through the subsurface encounters fluorine bearing minerals [32]. Through environmental studies of fluoride in the subsurface, there is a direct correlation between mobility of pH and fluoride [24]. Soils that are more acidic allow for an increase in fluoride mobility and leaching, where plant roots may subsequently accumulate the additional fluoride.…”

“…Groundwater quality maps were created using a modified version first discussed by Ducci [19], where thematic maps were initially produced using the interpolation method and subsequently stacked developing the total groundwater quality map [7,19,24]. The modified version utilizes a summation process, combining and calculating the six contaminants together, and defining regions of poor, medium, and optimum groundwater conditions (Table 4).…”

This study evaluates the groundwater qualities and environmental changes to obtain information on the groundwater contamination in the Permian Basin, Texas. Coupled with the U.S. government’s open data, these analyses can identify regions where environmental change could have affected groundwater quality. A total of thirty-six wells were selected within the six counties: Andrews, Martin, Ector, Midland, Crane, and Upton. Spatial distribution maps were created for six different parameters: pH, total dissolved solids (TDS), chloride, fluoride, nitrate, and arsenic. Total groundwater quality maps incorporate all the contaminants and denote regions of poor, medium, and optimum conditions. To identify spatial changes in groundwater quality, maps were separated into two different time intervals, 1992–2005 and 2006–2019. We found that groundwater contamination resulted primarily from the mobilization of the contaminant from anthropogenic activities such as chemical fertilizers, oil and gas developments. Overall, groundwater quality decreased during the study period from 1992 to 2019 as population and urban growth began to develop in the Permian Basin. This study contributes on understanding of the response of groundwater quality associated with environmental change in the Permian Basin. Therefore, this research provides important information for groundwater managements in developing plans for the use of water resource in the future.

“…juliflora by bioaccumulation and also improves mineral content and biomass (Chaudhary and Khan 2016). More recently, Chaudhary et al (2019) conducted a field study in the F − endemic area of Rajasthan state, India, and suggested that Pseudomonas fluorescence can increase F − bioaccumulation and biomass of F − hyperaccumulator arid plant Prosopis juliflora. More recently, Katiyar et al (2020) suggested biotechnological approaches in genetic manipulation for degradation and F − remediation by increasing interaction among the plant microbes.…”

Excess fluoride (F − ) inhibits the growth and metabolism of several crop plants, while some have an innate ability for F − tolerance. The present study was undertaken to explain how plants tolerate F − toxicity and understand the efficacy of exogenous stress protectants and phytoremediation approaches for F − homeostasis and tolerance of crop plants. This review comprehends existing information available so far on the F − accumulation toxicity and tolerance mechanisms. A high level of F − inhibits plant growth, water and nutrition uptake, enzyme activity, and yield. This review concludes that plants tolerate through F − homeostasis (exclusion, chelating, and compartmentalization) and gene activation for enhanced pathways of antioxidants, hormones, osmolytes, stress proteins, transporters, and metabolites. Exogenously applied stress protectants like salicylic acid (SA), polyamines (PAs), melatonin (Mel), glycine betaine, calcium (Ca 2+ ), and nanoparticles are differentially effective in reducing F − accumulation and toxicity by regulating various pathways. Application of minerals minimizes the F − accumulation through changing pH of soil, chelate formation with F − , and permeability of the cell membrane. Although many of the physiological aspects (enzyme activities, F − accumulation and regulation) were studied earlier, however, an effort has been made for the first time to understand the genetic basis and role of stress protectants and mineral nutrition, regulating these physiological activities, and explore new integrated approaches related to F − mitigation by means of phytoremediation. This review covers the recent development in F − transporters, gene expression, and biochemical and hormonal levels which could be utilized in regulating F − toxicity through omics and transgenic approaches in the future.

“…Membranes with specific pore size and compound-specific permeability are used for defluoridation, and this process includes reverse osmosis, nanofiltration through a membrane and electrodialysis [41]. Phytoremediation is being considered as an effective and low-cost remediation technique for the decontamination of soils [42][43][44]. Apart from these physical and chemical methods, biological processes for phytoremediation and defluoridation of soil, water or air using a bio-sorbent prepared from plant material and bioremediation through microbes have also been reported [41].…”

Fluorine is an essential nutrient, and excessive or deficient fluoride contents in water can be harmful to human health. The shallow groundwater of the Jiaolai Basin, China has a high fluoride content. This study aimed to (1) investigate the processes responsible for the formation of shallow high-fluoride groundwater (SHFGW); (2) identify appropriate methods for in situ treatment of SHFGW. A field investigation into the formation of SHFGW was conducted, and the results of experiments using soils from high-fluoride areas were examined to investigate the leaching and migration of fluoride. The results showed that the formation of SHFGW in the Jiaolai Basin is due to long-term geological and evaporation processes in the region. Stratums around and inside the basin act as the source of fluoride whereas the terrain promotes groundwater convergence. The hydrodynamic and hydrochemical conditions resulting from slow groundwater flow along with high evaporation and low rainfall all contribute to the enrichment of fluoride in groundwater. In situ treatment of SHFGW may be an effective approach to manage high SHFGW in the Jiaolai Basin. Since soil fluoride in high-fluoride areas can leach into groundwater and migrate with runoff, the construction of ditches can shorten the runoff of shallow groundwater and accelerate groundwater loss, resulting in the loss of SHFGW from high-fluoride areas through river outflow. The groundwater level will be reduced, thereby lowering the influence of evaporation on fluoride enrichment in shallow groundwater. The results of this study can act a reference for further research on in situ treatment for high-fluoride groundwater.
