Clipping Board » Environmental Pollution & Change ─ How dirty the human heart is, how dirty the environment will be...
Update Date: 2010/10/20 20:13 (Central News Agency Reporter Li Xianfeng, Taipei, 20th)
The Green Party today stated that the use of chlorine and polyaluminum chloride (PACL) in water treatment plants in New Taipei City is three to four times higher than in Taipei City's plants, potentially increasing the risk of Alzheimer's disease and cancer for consumers. The Environmental Protection Administration (EPA) responded that both are approved water treatment chemicals.
The Green Party held a press conference titled "No Good Water, No Peace," where convener Pan Han-sheng displayed water bottles containing samples from "Shimen Reservoir," "Yuanshan Weir," and "ditches near Yuanshan Weir," questioning the cleanliness of the water consumed by New Taipei City residents.
During the press conference, comparisons were made between the "Zhitan Water Treatment Plant," which supplies Taipei City, and the "Banxin Water Treatment Plant" and "Datan Water Treatment Plant," which serve New Taipei City and Taoyuan areas. The data showed that the use of liquid chlorine and polyaluminum chloride in the "Banxin" and "Datan" plants was 3.2 times and 4.2 times higher, respectively, than in the "Zhitan" plant.
Pan Han-sheng pointed out that the issue with polyaluminum chloride lies in the unknown proportion of residual aluminum in the water. According to the EPA's "Drinking Water Quality Standards," this parameter is not tested.
He noted that the European Union's standard for aluminum content in drinking water is no more than 0.1 milligrams per liter, while Taiwan has yet to establish safe limits for aluminum in food or water, potentially increasing the risk of cancer and Alzheimer's for the public.
Chen Dian-quan, a senior technical specialist at the EPA's Toxic and Chemical Substances Bureau, stated in an interview that the parameters in the "Drinking Water Quality Standards" are set by experts based on global standards, and polyaluminum chloride is currently an approved water treatment chemical.
Chen added that whether polyaluminum chloride is harmful to humans remains theoretically uncertain. The current reference standard is not mandatory. For example, the U.S. standard is 0.2 ppm. To ensure public drinking water safety, international standards will be considered when setting regulations. 991020
