Comparative Assessment of Physicochemical Parameters of Udaipur City, (Raj.) India

Urbanization and Industrial activities lead the water contamination. It’s a serious problem now a day. Analysis of the water quality is essential to take a safety measures to protect & preserve the natural ecosystem. As a part of this study, Assessment of the water quality was carried out for different lakes in the City of Udaipur. The present analysis is aimed to assess the physicochemical parameters of water in Udaipur City. For determining the present water quality status by statistical evaluation 35 different parameters have been considered Viz. pH, color, total dissolved solids, electrical conductivity, total alkalinity, total hardness, chromium, zinc, manganese, nickel, BOD, COD, fluoride, zinc etc. The study of physicochemical and biological characteristics of this water sample suggests the evaluation of water quality. The indices had been computed from Jan 2013 to Dec. 2015.


Introduction
Water is the most crucial factor in shaping the land and regulating the climate. It is one of the most important compounds that profoundly influence life. Wetlands are probably the earth's foremost freshwater resources that provide food and habitat for numerous aquatic life including threatened and endangered species. Therefore conservation of wetlands is pretty essential as wetlands are one of the most threatened habitats in the world. The most important step for conservation of wetlands is to maintain a proper water quality. The water quality is directly related to the health of the water body hence proper management of water quality of the aquatic environment is very much crucial.

Study area
The city of Udaipur (state Rajasthan, India) known as 'city of lakes' is situated about 600 m above the mean sea level and is located among the lush green hills of Aravali range between 24°35' N latitude and 73°42' E longitude. There are three major lakes around Udaipur and within, e.g., Fateh Sagar, Udai Sagar and Pichhola. The city population is around 0.65 million and It has a distinctly tropical climate with marked monsoonal effect. The climate of Udaipur can be divided into three distinct seasons, i.e., summer (Mar-Jun), rain (Jul-Oct) and winter (Nov-Feb). The average temperature ranges from 5°C in winter to maximum of 41°C in summers. The annual average rainfall ranges from 62.5 cm to 125 cm during normal monsoon regime. The climate is divided into three seasons, Summer(Apr-Jun), Rainy (Jul-Oct) and Winter (Jan-Feb). The present study was conducted on the Iron, Copper, Nickel,Total Kjeldahl Nitrogen. The analysis of Total Suspended solids, Total Dissolved Solids, Fixed Dissolved Solids, Fecal Coliform and Total Coliform of water performed as per the standard methods [10][11][12] in the laboratory.  The results of investigations of various parameters of Pichola lake water quality were recorded for two years (Jan 2013 to Dec 2014). During this period (Tables 1 & 2), analysis of various physicochemical parameters of different physical sites of Udaipur city was performed and it was revealed that the range of temperature in different sampling sites was 18 degrees centigrade (minimum) to 25-degree centigrade (maximum). The pH was found 7.70 (minimum) in the month of Jan-Feb, 2013) and 8.60 (maximum) (Tables 3-8).

Analysis of Ground Water Quality Parameters: A Review due to human and industrial activities, the ground water is contaminated [22]. This is the serious a problem at present. Thus the analysis of the water quality is very important to preserve and protect the natural eco system. The study of Physico-chemical and biological characteristics of this ground water sample suggests that the evaluation of water quality parameters as well as water quality management practices should be carried out periodically to protect the water resources.

Conclusion
The appraisal of lakes water in Udaipur's lakes with respect to bacteriological and physicochemical pollution is of immense significance for improving the living standard and quality of life in this region. Therefore, monitoring of microbial contamination and pathogenic bacteria genera on a periodic basis is important and useful to arrive at measures that can act as indicators of water quality and pollution.
