For example, at present because of the large number of factories upstream and midstream of the Tsengwen River, the amount of waste water has been constantly increasing, already accounting for 52 % of the pollution at the river mouth. If in the future the factories in the new zone also expel their waste water into the river mouth, this will affect coastal fisheries and breeding.
比如目前曾文溪河口，因為中、上游工廠林立，工業廢水排放逐年增多，已佔河口水汙染的百分之五十二，未來工業區工廠廢水若仍排放河口，對沿岸養殖業與漁場均有影響。
