Abstract

This study was conducted to investigate the trend of water quality fluctuations for 10 years (2007 - 2016) in the river waters of rural watershed in Jeonbuk Province. The average of CODMn in the study area was 4.17 mg L-1 and its median 3.47 mg L-1. EC averaged 0.22 dS m-1, its median was 0.19 dS m-1, and increased to October. The total nitrogen (T-N) content averaged 2.74 mg L-1, its median 2.40 mg L-1, and the total phosphorus (T-P) content averaged 0.09 mg L-1 and its median 0.07 mg L-1. The highest T-N content was 2.76 mg L-1 in April and the average T-P content was maintained at 0.09 mg L-1 during the investigated period.

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