Abstract
By means of providing food and habitat for aquatic organisms including the threatened as well as endangered species, wetlands serve as earth's most important fresh water resource. As a good wetland is determined by its water quality, it is exigent to maintain the proper water quality of a wetland as the water quality of the fresh water resources is deteriorating at an alarming rate. Due to the contaminated water quality, human population also gets affected as they suffer from many waterborn diseases due to its usage, some of which may prove fatal. Therefore, it has become imperative to check the quality of water bodies at regular intervals for their sustainable management. In order to access the water quality, various physio-chemical parameters were carried out from October 2015 to September 2017 at four representative sites (S1, S2, S3 and S4). During the present study, it was found that various physico-chemical parameters greatly influence the water quality of the under study wetland. The average results of these parameters were compared with ISI, ICMR and WHO standards for drinking water quality. It could be inferred that water quality at Ropar wetland is at S2 site and S4 site and Very Poor at S1 site and S3 site. DO and Free CO2 showed significant negative correlation with all other physico-chemical parameters at all the above mentioned sites.
Highlights
Wetlands are major resource of fresh water and it was very essential part of human life, mainly for drinking and domestic purposes
Water Quality Index (WQI)=∑WiQi/∑Wi=76.92 All parameters are expressed in mg/l except pH*
Various natural processes occurring during the rainy seasons, anthropogenic influences from domestic wastewater, agricultural activities, industrial effluents from National Fertilizer Limit (NFL) Nangal, ash from thermal plant and silt from cement plant and catchment area affect the water quality of Ropar wetland
Summary
Wetlands are major resource of fresh water and it was very essential part of human life, mainly for drinking and domestic purposes. In order to determine the state of pollution in our rivers, a continuous monitoring of water quality is essential. Communication of this information to the general public and the Government is very important so that the policies for the conservation of the precious fresh water resources are developed (Ali et al, 2000). Increase in population and industrialization, the demand of the freshwater increases in the last decades This demand fulfilled by the rivers which provide the water for human life and agriculture purposes. Slight change in the aquatic environment causes serious alterations in various abiotic and biotic
