Comparison of parameters of Lake in Chennai prior to and after monsoon

Abstract

Aim:The objective of this research article is to perform the effects of variation of chemical characteristics of water collected from Avadi lake compared with drinking water in pre-monsoon and post-monsoon periods. Materials & Methods: The samples were collected from Avadi Lake. The samples have applied chemical parameters for analysis of drinking water qualities was sample 8 (Group 1= 4 and Group 2 = 4) and calculation is performed utilizing G-power 0.8 with alpha and beta qualities are 0.05, 0.2 with a confidence interval at 95%. Analyzing the chemical characteristics of water is performed by the standard drinking water whereas the number of samples (N=4) and Avadi lake water are the number of samples (N=4). Results: The chemical characteristics of Avadi lake water of PH, BOD, COD, DO, Alky, and TH is 7.3, 35, 250, 450, 5.5 and 610 and the standard drinking water of PH, BOD, COD, DO, Alky, and TH is 7, 30, 10, 200, 10, and 380. The study has a significance value of p<0.05 i.e., p=0.022. Conclusion: The standard drinking water provides better outcomes in chemical characteristics of water when compared to Avadi lake water for analyzing the quality of water.
