Investigation to the water quality and environment of Bailuwan Wetland Park held by Chinese Environmental Protection Foundation was completed successfully at 30th, October, 2014.
Firstly, the volunteers obtained the data of water quality and environment before the building of Bailuwan Wetland Park from Jinjiang district Environmental Protection Bureau. Then they monitored the water quality using CODCr、NH3-N，TN，TP. Finally, they analyzed these samples in the research institution of water pollution control and waste utilization in Chengdu University of Information and Technology.
They found that the several major lakes had adequate water and on the average the water was more than 1.2 meters deep. There built up a pre-processing system in the upper-stream. Various aquatic plants grow in this water quality purification area, like clinopodium urticifolium and thalia dealbata.
The water quality of Dougou River would be greatly improved through this area after interception, sedimentation and degradation.
