Assessment of water quality and parameters leading to eutrophication in an urban water body

Abstract

This study has been carried out to assess surface water quality and the status of eutrophication in the UkkadamPeriyakulam lake which is a part of the Coimbatore Anicut channel system. The lake is fed by the canals of NoyyalRiver, it has a waterspreadarea of 320 acres and a storage capacity of 70 mcft. The water samples for assessment were collected during post monsoon period of the year 2018-19. The physiochemical parameters such as pH, Total dissolved solids, dissolved oxygen, electrical conductivity, chlorides, nitrates, sulphates, potassium, calcium, magnesium, sodium, phosphorus, total hardness; bio-chemical oxygen demand, chemical oxygen demand, lead and chromium were quantified. The various parameters are used to understand the spatial distribution. The suitability of water for drinking and irrigation purposes based on the results from Water quality index, Residual Sodium Carbonate Index, Sodium Adsorption is being discussed in this paper.
