Environment quality of surface water 1) Current situation of environment quality of surface From subsection 4.1.4 above it can be known that the surface water system in Xiangshan county seat mainly consists of three vertical and four horizontal canals, all of which finally empty into sea through the "three verticals" (namely, the Xidahe, Nandahe and Dongdahe Canals). Because it is impossible to monitor the water quality of all small streams, Xiangshan Environmental Protection monitoring station set routine monitoring stations on the representative three-vertical canals and Xinhuahe Canal. The results of main pollutants monitored there in 2014 are shown in Table 4.3-3. 4.3-3 Nanda River Network Water Quality Data of 2014 Unit: mg/L (not applied to PH) Total Volatile Cat.
