북한강수계 농업 소유역의 수질변화 모니터링 = Monitoring on Water Quality Changes of Rural Watersheds in the North IIan River Basin

다국어 초록 (Multilingual Abstract)

Stream and groundwater qualities of two rural watersheds in the upper North Han river basin were monitored for 14 months. Six to eight stream sampling sites and two to three groundwater monitoring wells were chosen and water samples were regularly collected and analyzed with respect to total nitrogen (T-N), total phosphorus (T-P) and total suspended solids (TSS). Monitored data were graphically analyzed with respect to time. Rainfall amount and intensity seemed to have an impact on stream T-N and T-P concentration changes. TSS concentrations were generally lower than the first class stream water quality standard. Both stream and groundwater qualities near livestock feetlot areas were degraded, indicating the feedlots have an impact on water quality.
