Author(s): Reju J, Thampiraj and *J.W.Prakash
Abstract: The present investigation assesses the water uniqueness of four ponds in the region of Venganoor town in Trivandrum district of Kerala, India where ponds have been conventionally used for harvesting rainwater for drinking and irrigation purposes. Ponds exist in this area is in most of the state of utter neglect and abandonment. Agricultural and urbanization activities take place all round the year in this city of ponds influencing the water quality. The physico-chemical characteristics like temperature, pH, transparency, turbidity, DO, nitrate, and total iron content are discussed in this paper over a period of one year. Water temperature broadly varied from 25.5 to 330C. Transparency fluctuated between 0.5 to 1.5m, the lowest in monsoon and the highest in pre-monsoon season with likewise turbidity between nil to 15NTU. Dissolved oxygen varied from 3.0 to 10mg/l. Nitrate concentration ranged from 3.1 to 9.6mg/l the highest in pre-monsoon seasons. The results indicate that there was much deterioration in water quality of these ponds. It is possibly due to bank erosion and surface run off.
