水的适用性for various domestics and potable uses was studied by analyzing samples from different bore well sampling sites, located in and around industrial areas in Aurangabad. The physico-chemical parameter of above sampling sites indicates that domestically used water is much more polluted. Maximum samples have high EC. TDS. TH. TA. Cl- . Ca++. COD. Values exceeding the permissible limits for drinking purpose. It is observed that the main sources of the pollution are due to industrial waste water, municipal sewage and lack of sanitation.

Introduction

Aurangabad District is located mainly in Godavari Basin and its some part towards North West of Tapi River Basin. This District’s general down level is towards South and East and North West part comes in Purna –Godavari river basin. The Aurangabad district’s North Longitude ( Degree) is 19 and 20 and East Longitude (Degree ) is 74 to 76.

Aurangabad is a success story of MIDCs efforts towards a balanced industrialization of the state. A city with no industrial background is today a thriving hub of industrial activity. Today Aurangabad has a renowned industrial area and is divided into four zones namely Chikalthana, Waluj, Chitegaon & Shendra. The industrialization in Aurangabad started in mid 70’s with companies like Lupin, API, Nirlep & Garware. The major industry sectors in Aurangabad are Automotive, Auto Components, Pharmaceuticals, Breweries, White goods/Appliances. Chikalthana, Waluj, Chitegaon and Shendra industrial zones were selected for the purpose of investigation. Many illiterate workers live near the industries and use bore well water for their domestic activities. So examinations of these water resources for various water quality parameters and ascertain their quality with respect to drinking water is of worth importance.


Material and Methods

Sixteen ground water samples were collected randomly selected from study area in the month of December 2007(winter) with all precautions and preserved as per the recommended procedures.1For sampling, bore wells, pump were permitted to flow for more than 10 min and required quantity of water was collected in pre-cleaned polythene containers and immediately.2

All chemicals (AR grade or Equivalent grade) and double distilled (DD) water (free from CO2) were used to prepare standard solutions3and determination of Water Quality Parameters (WQPs). Graduated pipettes and standard measuring flasks used in the present investigation were calibrated at room temperature (30 ± 0.1 0C) before use.

WQPs such as temperature, pH, and electrical conductivity were determined in the field it-self. The other WQPs were determined within 48-72 hour from the time of collection of sample.

Results and Discussion

Values reported in Table 1 are the values of (winter season) December-2007. A rise in temperature of the water leads to the speeding up of the chemical reactions in water, reduces the solubility of gases and amplifies the taste and odors.4At elevated temperature metabolic activity of the organism increases requiring more oxygen but at the same time the solubility of oxygen decreases thus accentuating the trace.5In the present study temperature of the ground water vary from 25.6°C to 27.2°C. Chemical and biological reactions are directly dependent upon the pH of water system. The pH of ground water obtained in range from 7.01 to 8.13. In the present work conductivity of ground water samples are in the range from 772.00 to 4631.00 mmhos/cm all the water samples are found to be well above the permissible limit (300 mhos/cm) as per BIS. In the present work, TDS of ground water samples are in the range 488 to 2885 ppm. The observed variation in result may be due to weathering of soil and rock. The water with high solid contents are of inferior palatability and may due to unfavorable physiological reactions in the transient consumers.6The high TDS levels (7500 ppm) will result in the excessive scaling in water distribution system. The alkalinity values are found to be in the range 240 ppm to 373 ppm. All samples are above permissible limit, 200 ppm, prescribed by BIS7and ICMR.8All the water samples in study area are very hard (>180 ppm). Most of the water samples can not be used for drinking purposes even in absence of other source (TH<600) except sample number S2, S3, S9 and S13. High chlorides contents in drinking water may also be the root cause for sodium sensitive hypertension in human being. Pollution through human faces, domestic sewage, bathing are the most important factors which increases the chlorides content.

Chloride contents (Cl-) are found to be ranging from 112.0 to 2047.0 ppm. The sulphate ions are found to be below permissible limit, 200 ppm concentration, in all samples studied. In the present work phosphate ion concentration vary from 0.125 to 0.185 which is well within the limit. Water with calcium content about 25 ppm is classified as calcium rich water. High calcium contents in summer months may be due to rapid oxidation of organic matter in the substrate.

在目前的调查钙浓度varies from 101.00 to 557.00 ppm. All the water samples studied in the present work are above permissible limit, 75 ppm. In the present work magnesium in ground water varies from 26.0 ppm to 170.0 ppm. All the values are well above permissible limit (20 ppm). Sodium content more than 50 ppm make the water unsuitable for drinking purpose. In the study area all samples are not suitable for drinking purpose except sample no. S
9as BIS9and WHO.10Concentration of potassium is less than 50 ppm in all the cases studied indicating that the water is suitable for drinking purpose. Taste for dissolved oxygen is generally not carried out for unpolluted waters. It is applied mainly for determining the D.O. of polluted waters and industrial effluents and constitutes a means of controlling pollution of water courses.11The taste is an indicator of the purity achieved during treatments such as activated sludge process and oxidation ponds etc. Deficiency of oxygen in receiving waters give rise to odoriferous products of an anaerobic decomposition. During present work dissolved oxygen ranges from 4.64 ppm to 7.44 ppm. Chemical oxygen demand, as the name implies is the oxygen requirement of a sample for oxidation of organic and inorganic matter. As the oxidisable inorganic matter is usually negligible in comparison with the quality of organic matter. COD is generally considered as the oxygen equivalent of the amount of organic matter oxidisable by the Potassium dichromate.

In the present work COD values vary from 60 ppm to 168 ppm. Higher values of COD are observed in some of the cases indicating high organic pollution.


Conclusion

Bore well water samples underinvestigation are generally used for domesticpurpose and only some time for drinking purpose.But looking at the results obtained it can beconcluded that bore well water is contaminated andshould not be used for drinking purpose withoutpretreatment.
