Sailu is considered to be the oldest and religious city in parbhani district of Marathwada region in Maharashtra, Sailu city is situated near Dudhana river. A famous Temple of "Keshavraj Babasaheb Maharaj" is situated in middle of sailu city. Who was Guru of Shirdis Sai baba.
The residents of Sailu tehsil usually use water form bore-well for drinking and domestic purposes. There is a huge variation in the concentration of dirrrent species due to factors like depth,diffrent land, under groundwater conditions, rain condition s etc. The present work attempts to evaluate the quality of groundwater in sailu Tehsil of Parbhani district for potability.
In the Present study thirty groundwater (borewell) samples were collected from diffrent sites of Sailu tehsil in brown glass bottles with necessary precautions and preserved as per the recommended procedures.¹
All the Chemicals used were of AR grade, Glass ware used were of 'A' grade.Double distilled water was used through out the work to prepare standard solution.²

Fluoride Concentration in aqueous samples were determined with fluoride-Ion Electrode (IRON)and ORION 407 A Ion meter. 25 ml of Aliquot was taken in polyuthene beaker and 25 ml of (TISAB-III) Total Ionic Strength Adjuster Buffer,ORION Application Solution was added. Ion meter was standardised against solution of known fluoride concentration in the standard sample and read directly on the meter scale. The scale was calibrated in ppm of fluoride concentration in water.

Fluoride has little significance in industrial waters, but in amount of 1 to 1.5 ppm it is an effective preventive of dental curies. Above this amount, fluoride may causes dental fluorosis and skeletal fluorosis. such water should be defluoridated to reduce the fluoride concentration to the acceptalbe levels.
In the present work fluoride concentration varied from 0.11 to 0.38 ppm. The values obtained are well below permissible limit, 1 ppm, prescribed by ICMR.3
