Water is very important for our life. And it is abundantly available in nature. For the investigation we have collected four sample near Parichha thermal plant. Water samples are collecting in February, May, August, NovemberMonth. During physiochemical analysis fluoride have found in very excess amount in groundwater sample collected from resources of drinking water near Parichha thermal plant. While fluoride levels can vary greatly, some fluorides are found naturally in soil, air, and water. Fluoride is present in almost all water. Foods derived from certain plants and animals have also fluoride, Fluorides enter the body and pass through the digestive system before entering the bloodstream. They are carried by blood and tend to gather in calcium-rich tissues like teeth and bones. Our society is now at serious risk from fluoride contamination on a worldwide basis. The water source's fluorination is mostly due to volcanic activity, fluoride-rich soil, and human activity. The World Health Organization recommends 1.5 mg/L of fluoride for drinking water to prevent dental mottling and skeletal fluorosis because of the negative health effects, which include dental discolouration and skeletal fluorosis. "In addition to skeletal and dental fluorosis, excessive fluoride in water can cause osteoarthritis, arthritis, fatigue, joint problems, muscle damage, and chronic illnesses. In extreme situations, it can damage a living thing & #39; s heart, veins, kidney, liver, sensory organs, and neurological system, as this research discusses.
