Abstract
Today the environment has become harmful for the health of living organisms due to excessive pollution and contamination of natural resources. The present investigation has been carried out with the objective to assess the water quality of the Gobind Sagar Lake, Bilaspur, Himachal Pradesh (India) using physico-chemical parameters with heavy metals of the lake. For this study, three sampling sites were identified and samples from different sites were collected in summer season and important parameters [Water Temperature, pH, Total Hardness, Dissolved Carbon Dioxide (CO2), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Chloride, Total Alkalinity, Total Dissolved Solid (TDS)] with heavy metals [ Lead (P), Copper (Co), Iron (Fe), Cadmium (Cd), Nickel (Ni) and Manganese (Mn), Chromium (Cr) were analyzed. The results revealed that the different conditions of Gobind Sagar Lake in different sampling stations showed fluctuations in some physico-chemical parameters and also in heavy metals. These result depicted that water of lake was polluted in the form of nutrient enrichment which is due to agricultural activities and its runoff in and around catchment area of the lake. There are other many ways that things can end up in the lake as the free style way of disposal of industrial and domestic effluents etc. Results of studies on heavy metals in pollution are well documented revealing the toxic effects of these metals on aquatic organisms.
Highlights
India is facing a serious problem of natural resources scarcity, especially that of water in view of population growth and economic development[1]
The results shows that these values are below the maximum permissible limit, results show deviation of 3 approximately at all sampling stations and these deviations are due to sampling in different months of the summer season
The results shows that these values are below the maximum permissible limit, results show deviation of 1 approximately at all sampling stations and these deviations are due to different sources of pollutions at different sampling station
Summary
India is facing a serious problem of natural resources scarcity, especially that of water in view of population growth and economic development[1]. Most of fresh water bodies all over the world are getting polluted, decreasing the portability of water2 & 3. We need water for different purposes such as dinking, irrigation, industries, swimming, fishing etc. Water for different purposes has its own requirements in terms of composition and purity as well as the presence of different components in water has to be analyzed on a regular basis to confirm its suitability. Major sources of water pollution are from municipal water, industrial water, agricultural water, sewage water, etc. Without adequate quantity and quality of fresh water sustainable development will not be possible[6]. Contamination of water is Sharma & Walia, Curr.
