A holistic study on fluoride-contaminated groundwater models and its widespread effects in healthcare and irrigation

Groundwater is a key resource in the world. Its importance is often undermined, despite the various applications which include irrigation, drinking, sanitation, and industrial uses. One of the contaminants of groundwater is fluoride or the fluorine ion. Fluoride is a common pollutant of water, carrying potential benefits and costs to various sectors. Fluoride contamination of groundwater can impact humans, animals, healthcare, and the agricultural sector in direct or indirect ways. This paper aims to establish the definition of fluoride contamination of groundwater and simultaneously provide an outline of a few common sources that may cause fluoride contamination. Furthermore, this study will lay out the impacts of fluoride-contaminated groundwater on two sectors: healthcare and agriculture/irrigation. This study will also summarize various other research projects conducted across the world, which deliver promising evidence to support the points made throughout the paper. In addition to a detailed analysis of the impacts of fluoride on the healthcare and agricultural sector, this study also evaluates few other challenges which this issue poses and how to overcome them in the near future. A summation of deflouridation techniques is included, along with the future scope pertaining to the field of fluoride contamination. Another objective of the study is to spread awareness about the various health impacts that fluoride contamination poses and encourages consumption of fluoride in accordance with the set limit of 0.5-1.5 mg/L. The motivation behind writing this review is to compile and document various researches, along with an address on this prevalent issue to minimize the detrimental impacts and potential health risks on the society. The results of this study help to minimize risks in the future and encourage scientists to come up with mitigation strategies to ensure a safer environment.
