U., Gorepatil P. B, Mane Y. D., Ingle V. S. Abstract -The groundwater is determined of five tehsil of The water temperature, pH, DO, EC and TDS were analyzed Osmanabad district of Maharashtra, where samples are under immediately on the spot after collection, whereas the studied for Physico-chemical status of groundwater. In Physico- analyses of remaining parameters were done in the chemical analysis, the water quality parameters are measured like pH, temperature (T) turbidity (TUB), electrical conductivity laboratory. The study was carried for a period of 1 year (EC), total dissolved solids (TDS), total hardness (TH), content of (June 2010 to May 2011). Monthly data was collected, but calcium (Ca+2), magnesium (Mg+2), sodium (Na+), potassium results were represented in three seasons. Four month make + - -2 (K ), chloride (Cl ), sulphate (SO4 ), total alkalinity (TA), one season like first March to June summer season, July to dissolve oxygen (DO). Physico-chemical studies of twenty October monsoon season, and November to February winter groundwater samples from different tehsils of Osmanabad season. Power of hydrogen (pH) was determined district was carried out during the month of May 2011 and outcome of the results were discussed. electrometrically using digital pH meter, electrical conductivity was measured by digital conductivity meter, Key Words: Physico-chemical analysis; ground water; dissolved oxygen is measured by Winkler’s method, total Osmanabad district; TDS; TH. dissolve solid was measured by using TDS meter and similarly turbidity is measured by evaporation method.

INTRODUCTION Alkalinity is measured standard procedure [13], chloride by Water plays an important role in living life on earth. argentometry, calcium, magnesium, total hardness by Recent years increase in urbanization, industrialization, complexometric titration method, nitrate and phosphate uses of pesticides in agriculture and human activity has were determined by method suggested [14-16]. Estimation increase the pollution of water. Recently, the WHO of sodium was done by Flame Photometric method. reports that 65% of rural and 36% of urban Indians was without access to pure drinking water [1]. Osmanabad is III. RESULTS AND DISCUSSION considered to be oldest and religious district of Twenty ground water samples were selected from the study Maharashtra state. A famous temple of goddess area. The results of fifteen physicochemical parameters of Tuljabhavani is situated in Tuljapur taluka and historical ground water are presented. The data presented in table 1, 2 Naldurg fort is situated near Naldurg town. The peoples and 3 season wise respectively. Some of the interesting of Osmanabad district usually use water from dug well and observation of ground waters is summarized below. bore well for drinking and domestic purposes. There is a huge variation in the concentration of different species due A. Temperature (T): to factors like depth, different land, underground water The heat released by decomposition of organic matter and conditions, rain conditions, and industrialization etc. The respiration may significantly raise the temperature in present work attempts to evaluate the ground water quality polluted water. The change in atmospheric temperature with in Osmanabad district. change in season brought corresponding change in the water temperature. In the present investigation maximum value of II. MATERIAL AND METHODS water temperature were recorded in summer season In present work study twenty ground water samples from corresponding with the atmospheric temperature [17-19]. four tehsils of Osmanabad district were collected during During summer water temperature was higher because of morning hour. The water samples were collected in the low water level, clear atmosphere and greater solar radiation glass bottles with necessary precautions and preserved as and lower water temperature in the rainy and winter season per the recommended procedures [2-11]. All the chemicals can be explained on the basis of frequent clouds, high used were of AR grade and double distilled water was percentage of humidity and high water level [20]. The other used throughout the work to prepare standard solutions reasons may be due to the fact that the particles floating in [12]. water absorbs heat more rapidly than the water itself. These particles in term radiate their heat to the surrounding water thereby increasing the temperature of water [21]. Seasonal variation showed that the temperature value is maximum Manuscript Received on September 21, 2014. during summer and minimum during winter which can be Patil D.

Our results are in carbonic acid, leaching of rocks and weathered products. agreement with this observation. Seasonal fluctuations in pH Ruttner et. al. [33] has also recorded the similar results. values were also reported by Sireenivasan et. al. [23], Vyas Decrease in alkalinities was observed in rainy season during and Kumar [24] while Sumatra et. al. [25] could not notice the present investigation which may be due to dilution seasonal fluctuation in pH. However maximum pH is effects. Similar trend was also observed in the earlier observed during winter is in agreement with Goels et. al. findings [34]. [26]. The reason for higher value of pH in winter may be E. Total hardness (TH): due to the growth of microscopic as well as filament algae which utilize carbon from carbonates, sulphur from Hardness values are higher in most of the cases as per sulphate, and nitrogen from nitrates and phosphorus from WHO [29]. The hardness values are high in almost all the phosphate converting them into hydroxyl ion which are sample studied in summer which may be due to decrease responsible for increase in pH reference. The lower pH in water table. The values are low in winter and rainy during rainy season and winter and higher values in summer which is mainly due to dilution. season may be due to increase in the temperature which F. Chloride (Cl-): enhances the microbial activity causing excessive production of CO2 [27]. In the present work pH value varies It has been observed from tables that the concentration of in between 6.32 to 8.33 throughout the year for all sampling chloride ion is found to be lower in the baseline stations but is suddenly found to be increased at the stations situated in stations which are within the permissible limits according to the vicinity of industrial areas. The abnormally high values water quality standards [28-29]. of chloride concentrations in above cases indicate high C. Electrical conductivity (EC): degree of pollution may be due to discharge of either The conductivity is an important parameter for providing domestic or industrial waste i.e. high degree of pollution. an indication of ion concentration in the water. It has been The maximum value of chloride content in summer whereas in rainy season it is low. Higher value of chloride may be observed from tables that the conductivity values vary due to domestic sewage, bathing and pollutants from significantly with season in all the study sites, however industries. these values are high and water samples are unsuitable for -2 drinking purposes when compared with drinking water G. Sulphate (SO4 ): specification [28-29]. In the present investigation Sulphate concentration is high in case of samples close to maximum conductivity values were observed in the water industrial areas and near municipal and industrial wastes samples near canals carrying industrial effluents, bore-well leading to enhancement of sulphate concentration in ground samples from industrial areas. Usually high conductivity water. Higher values of sulphate in summer may be due to values are observed in summer as compared to rainy and reduction of water level and constant industrial waste winter seasons, which is in agreement with the observation pollution. made by Rao et. al.

Total Dissolved Solid (TDS): In the present investigation the high value of calcium and TDS values in present work are higher than the magnesium are observed in summer and low values in rainy permissible limit in most of the cases which is clear and winter season. This may be due to dilution of calcium in indicating that the ground water in some of the locations is rainy season. It has been found that the disposal of sewage very hard [28] and unsuitable for drinking purposes. In the and industrial wastes are important sources contributing
