Response to river water quality accidents
Last Updated June 14, 2024
When receiving complaints such as "fish floating in the river", "river turbid", "oil floating", etc., conduct on-site surveys as necessary and cooperate with the Green Environment Bureau To deal with it.
In addition, we will identify and provide guidance on the cause. The cause may be subject to penalties imposed by laws and regulations or charged for recovery costs.
