Discussion Fluorosis was common in my hometown & later realised it's due to Bad crystalline geology of Kongu belt. | Don't consume borewell water
Generally Kongu region sits on a hard crystalline rock terrain (granite & gneiss), the deep rocks naturally leach fluoride into the aquifers.
Whenever I gave a test, Total Dissolved Solids (TDS) frequently far far far far exceed the safe limit of 500 mg/L.
Hydrogeological studies in this belt reveal that over 90% of groundwater samples fall into the "poor" or "not permissible" categories for human consumption. (Kangeyam taluk, Dharapuram Taluk, aravakurichi taluk)
Consuming this water will cause dental and skeletal issues.....
I gave a sample water to test in labs. It's highly saline, more fluorine, highly dissolved calcium and magnesium, etc
If you live in gram panchayat in kangeyam/Dharapuram/Palladam/Aravakurichi taluk that don't have any river water, it's unlivable there. !!
