| Abstract |
| This study investigated water quality of freshwater lakes and inflow streams in the six west reclaimed lands (Shihwa, Hwaung, Sukmoon, Iweon, Nampo and Saemangeum) once every two months from April to October in 2015. The measured pH and electrical conductivity of the water samples ranged 7.6~9.2 and 0.004~0.426 ds m-1, respectively. The concentrations of dissolved oxygen (6.9~10.5 mg L-1), biochemical oxygen demand (0.2~18.1 mg L-1), chemical oxygen demand (3.4~100.6 mg L-1), total organic carbon (0.2~8.9 mg L-1), suspend solid (2.4~86.3 mg L-1), total nitrogen (0.2~4.4 mg L-1), and total phosphorus 0.03~0.21 mg L-1 also varied in a wide range. Correlation of water quality analysis with concentration of EC between COD and TOC was higher. Recently, watershed management system necessary to sustainable water quality monitoring of agricultural water for water environmental conservation in water pollution. It is need to be ensure the water quality of reliable agricultural water in the watersheds. Our results can provide some useful information for deciding water quality management plans at freshwater lake and watersheds. |
