Introduction

Industrialization and urbanization created serious problems of water pollution of surface water i.e. ponds, underground water tube-wells. In developing countries like India, this problem has become acute day by day.

In the present study, the levels of DO were studied in the vicinity of Halsiddhanath sugar factory located at Nipani. The underground water sample were taken from twelve underground tube wells in the glass bottles by following standard procedure. Sample were taken from twelve underground tube wells which are located at 1. Bhim Nagar, 2. Nagoba lane, 3.Kharade lane, 4. Namar mal, 5. Shivaji Nagar, 6. Andolan Nagar, 7. Kmgar Chowk, 8.Ambale polt, 9. Mestri Nagar, 10. Ramling Temple, 11. Mestri Nagar, 12. Bhise lane. The samples were collected every month throughout the every year and analyzed in laboratory for the levels of DO.

Results and Discussion

Dissolved Oxygen

The average concentration of oxygen is 20.90 %. DO content was always above 5mg/litre and went up to 12.56 mg/lit. DO values were extremely low at Ashray Nagar and Pratibha Nagar and confluence of Andolan Nagar and Azad Nagar (Sample sites 3, 4 and 5) because of high loads of organic matter in the present study.

Layout Do observed during rainy season and further reduction in summer at various sampling stations is due to more of waste and clean natural fear of surface waters. (Table 1 & 2).
