According to the Shenzhen News Network, a Shenzhen citizen recently posted on the People's Online leaders' message board saying “the tap water used by residents is serious and smelly.” After receiving the complaint, Shenzhen Shenshui Baoan Water Group Co., Ltd. carried out a summary table and testing the faucet water of community users. After testing, the water quality passed, and no problems reflecting water quality were found. The response mentioned: 1. Preliminary analysis showed that users reported that the serious problem of scale when boiling water was a water problem in the Xijiang River. The higher the hardness, the more obvious the phenomenon of scale. The national “Domestic Drinking Water Hygiene Standard” stipulates that the total hardness limit for tap water is 450 mg/L, which is similar to the World Health Organization standard. The hardness of tap water in Shenzhen is between 30-120 mg/L, which is far below the upper limit of the standard. 2. Shenzhen is one of the cities with severe water shortages in China. In order to meet the city's water needs, on the basis of water supply from the Dongjiang River, Shenzhen will introduce Xijiang water sources in June 2024, forming a new pattern of dual water source guarantee for the Dongjiang River and the Xijiang River. The water of the Xijiang River originates from the Wumeng Mountains in Qujing City, Yunnan Province. After flowing through Guizhou and Guangxi, it enters Guangdong. The water area covers more than 32 million people. Both Xijiang Water and Dongjiang Water are high quality water sources, so citizens can drink it with confidence. 3. Complainted users reported water quality problems with scale and floating matter after boiling tap water. This is due to the high hardness of Xijiang water after using it, and it has no effect on the human body.
