Abstract
The water quality of Anyang stream, the first tributary of Han River, was investigated from 2006 to 2010. The concentrations of nutrients and organic contents such as ammonia, nitrite, nitrate, phosphate, and chemical oxygen demand in water were measured by grab sampling analysis. Water samples were collected at the marked point for five years. According to pollutant levels, Anyang stream was divided into six zones. Spatial changes of annual water pollution were demonstrated using zone identification and strip analysis technology.
Key Words: Anyang stream, annual pollution levels, spatial change, nutrients, organic content
