Until authorities receive conclusive analysis results for the collected water samples, Inspectors from the Wenzhou Environmental Protection Bureau look for answers elsewhere. Some residents related that the event happened within one hour, after 5 a.m., when the river was last seen clear.
This is why investigators believe that someone polluted the river with artificial colouring agents. Regulations involving their environment were clearly broken and now the culprit is being searched. According to the first opinions it is believed that who ever dumped artificial colouring in the water hoped to loose tracks after heavy rain as a powerful typhoon was announced.
Jianfeng Xiao, chief of the Wenzhou Environmental Protection Bureau, detailed this in the following statement: “We suspect that somebody dumped artificial colouring in the water because he thought the typhoon yesterday would cause heavy rain, and nobody would notice… It turned out there wasn’t heavy rainfall yesterday, so the evidence is left behind”
