On July 20, the Jiulong Ecological Environment Bureau of Ganzi Prefecture, Sichuan issued an information notice: At 15:38 on July 20, the blogger “Zhu Kai Fishing” reported that a large amount of black water was discharged into the Yalong River in Zier Township, Jiulong County, Ganzi Prefecture, and the pollution zone was tens of kilometers long. Before the blogger posted this piece of information, our bureau had discovered that the water in the Zier River had turned black and organized staff to carry out traceability checks, and reported it to the State Bureau of Ecology and Environment to carry out a comprehensive traceability investigation on the section of the river in Ganzi Prefecture. There were no mining companies or vents along the way that caused the water to turn black. At the same time, rapid water quality tests were carried out at the three points of the upstream entry section, the midstream comparison section, and the downstream inlet section. Ammonia nitrogen, total nitrogen, total phosphorus, and chemical oxygen demand did not exceed the standards. The State Department of Ecology and Environment has dispatched law enforcement monitors to the scene for further inspection. Thank you all for your interest in our county's ecological and environmental protection work. Further inspection results and water quality test reports will be promptly reported.
