Alarming Levels of Fluoride in Bathinda’s Drinking Water: A Wake-up Call for Public Health

A recent study titled “Assessment of Fluoride Exposure and Associated Health Risks from Different Sources of Drinking Water to Various Age Groups in Bathinda City, Punjab, India,” conducted under the DBT Star College Scheme, Department of Biotechnology, Ministry of Science & Technology, Government of India, has unveiled a sobering reality. The study, recently published in the esteemed journal ‘Physics and Chemistry of the Earth’ by Elsevier, reveals distressing findings about elevated fluoride levels lurking in Bathinda’s drinking water sources. This study has been conducted by Dr. Vikas Duggal, who is an Assistant Professor in the Department of Physics at DAV College Bathinda, with his team members – Tanisha Goyal, Ramandeep Kaur, Jashandeep Kaur, and Garima Bajaj.
The investigation meticulously analyzed 296 water samples, encompassing a variety of sources such as groundwater, surface water, municipal reverse osmosis water (both pre-monsoon and post-monsoon seasons), public water supply, bottled water, private reverse osmosis water, and rainwater. Most shockingly, a significant proportion of the tested water sources, including groundwater (78.4%), municipal reverse osmosis water (72.1% pre-monsoon, 27.9% post-monsoon), public water supply (14.3%), bottled water (37.5%), and private reverse osmosis water (25%), far exceeded the recommended guideline value of 1.5 mg/L for fluoride, as recommended by the World Health Organization and Bureau of Indian Standards. The findings reveal potential health hazards, including the risk of skeletal and dental fluorosis, casting a shadow over the region’s overall well-being.
The study revealed that fluoride levels in 72.1% of the municipal reverse osmosis water samples exceeded the permissible limit in the pre-monsoon season, while in the post-monsoon season, this occurred in 27.9% of the samples, indicating a potential health risk. The findings suggest that the RO plant reduces the fluoride content in groundwater, but even after filtration, the fluoride level remains above the WHO guideline value, making it unsuitable for consumption. The results of the study reveal that private reverse osmosis water is safe for drinking only when households use public water supply for RO processing.
The study revealed that the fluoride concentration in 37.5% of the bottled water samples exceeded the WHO permissible limit, rendering them unsuitable for drinking. Additionally, the study found significant variations in fluoride levels among different brands of bottled water. Furthermore, when analyzing different batches of the same brand, substantial fluctuations in fluoride levels were observed, indicating a lack of regulation.
The study computed the non-carcinogenic risk of fluoride in various drinking water sources for different age categories, including infants, children, teenagers, adults, and senior citizens. It revealed that children are the most susceptible group to non-carcinogenic health repercussions arising from fluoride exposure, followed by teenagers, adults, senior citizens, and infants in sequential order.
The investigation also identified specific safe drinking water sources, particularly the hand pumps situated alongside the Sirhind Canal. Eight groundwater samples were collected from these hand pumps, and they were found to meet the recommended fluoride limits, making them suitable for direct consumption. Many people from the adjoining colonies of the canal, and even some from outlying areas, use this water for drinking motives. There is usually a rush of people to collect water in containers in the morning and evening, which is why in some places, four hand pumps are installed close to each other.
This study demonstrates that prolonged consumption of high levels of groundwater, municipal reverse osmosis water, private reverse osmosis water, and bottled water can result in dental fluorosis, skeletal fluorosis, and other health issues. Given the implications of these findings, it is crucial to implement remediation measures aimed at reducing fluoride levels in contaminated water sources.
Principal Dr. Rajeev Kumar Sharma applauded Dr. Duggal and his team for their research on immediate concerns for Bathinda city residents. He mentioned that this research would help educate the community about the dangers of excessive fluoride in various sources of drinking water.
