The present study focused on the hydrochemistry of groundwater in parts Chandauli-Varanasi region to assess quality for determining its suitability drinking and agricultural purposes. Urbanization agriculture activities have a lot impacts area. A total 70 ground water samples were collected randomly from different sources viz. hand pump, dug wells bore wells, analyzed major cations anions. domination anions was order Na > Ca Mg K HCO3 Cl SO4 NO3 F. Piper classification hydrogeochemical...
Around 9000 inhabitants in the Panda River basin, Sonbhadhra District, Uttar Pradesh, India, are vulnerable to a “silent” dental and skeletal fluorosis from groundwater consumption. The fluoride source seasonal quality variation were studied by collecting 65 samples Upper basin. Major rock types phyllites granite gneissic rocks. Fluoride concentrations range 0.4–5.6 mg/L pre-monsoon season 0.1–6.7 post-monsoon season. Fluor-apatite biotite mica identified as main provenance of through...
