Abstract

This study aimed to identify the changing trends in the agricultural water quality of the major watersheds in Chungnam Province over a 10-year period ranging from 2007 to 2016. The results of water quality analysis revealed that the mean chemical oxygen demand was 4.1 mg L^-1, with the median values being 4.0 mg L^-1. The result of annual COD_Mn of stream water showed tendency to increase. The mean and median values of EC (electrical conductivity) were 0.21 dS m^-1 and 0.19 dS m^-1, respectively. The mean T-N (total nitrogen) was 2.91 mg L^-1, with the median values being 2.47 mg L^-1. The mean and median values of the T-P (total phosphorous) content were 0.11 mg L^-1 and 0.07 mg L^-1, respectively.

Changes in annual water quality index in April, July, and October.
