Abstract
The present study deals with the water quality assessment of surface water from Valiakulam pond for a period of one year. The physico chemical parameters of water samples were analyzed based on standard laboratory procedures.. The present study aimed to analyze the influence of seasonal variations on physicochemical parameters of pond water. The parameters of water such as temperature, PH, transparency, turbidity, conductivity, hardness, alkalinity, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and free carbon dioxide (CO2) were studied from four stations of the pond. Results of the data were subjected for statistical analysis such as correlation and two way ANOVA with post hoc test. The results of ANOVA showed significant difference in all the twelve physicochemical parameters between the seasons and no significant difference was observed between study sites (P<0.05). The analysis of post hoc test in the form of Tukey also showed the same pattern. The results of the study concluded that the physicochemical parameters of pond water can be used for domestic propose. The results of the study may become useful data for productive water resource utilization in future.
