Geological Composition:

• Telangana’s geological formations contain fluoride-bearing minerals, which dissolve over time, releasing fluoride ions into the groundwater.
• The leaching of fluoride from rocks and soils directly influences the fluoride content in the water, making it a prominent cause of fluorosis in the region.

Hydrogeological Conditions:

• The hydrogeological conditions of Telangana play a pivotal role in the prevalence of fluorosis.
• Factors such as the nature of aquifers, groundwater flow patterns, and the interaction of water with geological formations determine the concentration of fluoride in the groundwater.
• Certain areas may have aquifers with higher fluoride content, leading to localized fluorosis issues.

Weathering of Rocks:

• The natural weathering of rocks in Telangana contributes to the release of fluoride into the water.
• Over time, the continuous erosion of geological formations results in the dissolution of minerals containing fluoride, further increasing the fluoride concentration in groundwater sources.

Agricultural Practices:

• In some instances, agricultural practices can exacerbate the fluorosis problem.
• The use of certain phosphate fertilizers and pesticides can contribute to the release of fluoride into the soil, subsequently affecting the groundwater.
• Runoff from agricultural areas may carry elevated fluoride levels, impacting nearby water sources.

Groundwater Overexploitation:

• Excessive extraction of groundwater for agricultural, industrial, and domestic purposes can intensify fluorosis.
• Over-exploitation lowers the water table, causing an increase in the concentration of fluoride in the remaining groundwater.
• This phenomenon is particularly significant in regions where groundwater is the primary source of drinking water.

Lack of Alternative Water Sources:

• Many communities in Telangana rely heavily on groundwater for their daily water needs due to the absence of alternative water sources.
• Limited access to treated or alternative water exacerbates the exposure to high fluoride levels, as communities are compelled to use fluoride-contaminated groundwater for various purposes, including drinking.

Industrial Activities:

• Certain industrial activities can contribute to the fluoride load in the environment.
• Effluents containing fluoride from industries, if not properly treated, can contaminate local water sources.
• This is especially relevant in areas with industrial clusters where regulatory measures for effluent treatment may be inadequate.
• This is especially relevant in areas with industrial clusters where regulatory measures for effluent treatment may be inadequate.
• Understanding these causes is crucial for designing effective mitigation strategies. Initiatives aimed at water purification, alternative water sources, sustainable agricultural practices, and strict industrial regulations can collectively address the root causes of fluorosis in Telangana, ensuring a healthier environment for its residents.

Q. In 2020, the state government declared Telangana as a Flourosis free state. In this context discuss the strategy adopted by the successive governments in addressing this problem.
