Introduction

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 Femous 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.

Material and Methods

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 solution²

Results and Discussion

Thirty ground samples were collected from diffrent sites of sailu tehsil. The results indicates that the quality of ground water has wide variation which is reflucted by the values of electrical conductivity, Chloride, Sulphate, Calcium and Magnesium etc.

pH acts as index to determine the extent of pollution, chemical and biological reactions are direatly dependent upon the pH of water system. In the present study pH ranged from 7.17 to 8.48 which lies in the range preseribed by WHO¹¹Electrical conductivity Value, in present study renged from 435.50 to 3112 all were found to be well above the permissible limit and are quite unfit for drinking.

Drinking water quality is affected by the presence of soluble salts.Total dissolved solid (TDS. is an important parameter in drinking water quality standard. It developes a perticular test to the water and at higher concertration redudces its potability, plants are also severely affected by higher values of TDS in irrigation water. TDS value of study area ranges from 294.86 to 2023.40 ppm. The high TDS level (7500. will result in the excessive scaling in water distrubution system¹².Total alkalinity (T.A.. were found to be in the ranges 265 to 485 ppm. All samples are above the permissible limit precribed by ICMR.¹³The higher alkalinity of groundwater owing to the presence of bicarbonates and trace amount of carbonate¹⁴and hydroxide salts.¹⁵Water hardness is traditional measure of the capacity of water to reacts with soap Hardwater couse horrific effects in digestive system moreover, the possibility of forming calcium oxalate crystals in uninary track has been ascertained.The hardness value of groundwater in the present study area ranges from 282 to 1150 ppm.

Chloride content were found to be ranging from 247.79 to 347.90 Chloride in the maximum sites was found to be well above permissible limit which may be due to the absence of proper drainage system in the study area. According to ISI permissible limit of sulphate concentration is 150 ppm, Beyond this limit sulphate causes gastro intestinal iritation and can have laxative effect in presence of Mg and Na.sulphate renges from 240.28 to 449.90 ppm. in the present work Calcium in present study varies from 100.20 to 144.28 ,High concentration of calcium may be due to leaching of soil deposit of limestone, dolmite, gypsum, pypsiferous materials, silicious sand into ground water. Magnesiun is an essential mineral for the living body, High concentration of mg couses nausea, musular weakness and paralysis in human body when it reaches up to the level of about 400 mg/L. In this area, magnesium concentration ranged form 0.48 to 211.97 ppm. Sodium and potassium enters in drinking water from natural geological sources, detergents, domestic industrial dischages and minig wastes. In the present work. sodium concentration varies from 32 to 445 and potassium varies from 9.5 to 95 ppm. Oxygen is disolved in most water in varying concentrations. Solubility of oxygen depends on temperature, pressure and salinity of water. It is essential to the life of fish and other aquatic organisms. In the present study Dissolved Oxygen. ranges from 5.24 to 6.03 ppm.Turbidity is an important parameter for characterising water quality.In the present study turbidity varies from 1.5 to 3.00 NTU. These values are well below the permissible limit as per WHO (5 NTU.¹¹
