Chinese urban water information transparency list, tap your home qualified? Author: admin Posted on: 2015-03-11 02:23:34 Text: [big] [medium] [small] With the frequent exposure of water pollution incidents, the public's growing concern for water safety, water quality information disclosure requirements voice has become more intense. In contrast, the pace of the country in water quality information disclosure on the much slower. November 2014 - January 2015, the China Social Assistance Foundation Charity Fund Water Security in China last three months for drinking water residents of 29 cities nationwide sampling testing. The water samples were taken from each urban area, as people's daily life with a terminal water, a total of 89 water samples extracted effectively. We were selected to detect a 20 key indicators, including total residual chlorine, PH value, turbidity, total hardness, chloride, sulfate, oxygen consumption (CODmn), copper, iron, TDS (total dissolved solids), 10 Items sensory indicators and chemical indicators; nitrate, fluoride, lead, cadmium, chromium, and other five toxicological indicators; two microbial indicators of total bacteria, total coliform, etc., and an organic indicator TOC (total organic carbon). Test results showed that 20 drinking water Indicator 29 cities 15 cities all qualified, accounting for 52% of total urban sampling; 14 cities presence of one or more indicators of failure cases, accounting for the city's total sampling 48%, of which there are four indicators of failure Changchun. Chlorine content in water samples over eighty percent of non-compliance in accordance with the "drinking water health standards" (GB5749-2006) requirements, total residual chlorine content of tap water pipe greater than or equal to 0.05mg / L. "Chlorine is added to the water in the factory, mainly water pipe in order to remove bacteria and other substances. Only the water residual chlorine content of 0.05 or more, to ensure the pipes of water theoretically be effective sterilization." Department of Housing and Urban Water Supply group of experts Professor, School of Environment, Tsinghua Zhansheng said. The test results showed that in 23 effective water samples, only four of total chlorine in water samples reached the national standard, and the remaining 19 water samples were unqualified, accounting for 83% of the total. This total chlorine content of 19 water samples were from unqualified Jinan, Changchun, Zhengzhou, Wuhan, Xi'an, Wuxi, Nanjing, Harbin, eight cities. The consequences of non-compliance caused chlorine content may be very serious: "Once the water pollution incidents, a number of infectious germs would be through a pipe into every household, may cause outbreaks of epidemic diseases." Beijing public health drink Water Research Institute executive director Zhao Feihong said. However, she also stressed that the chlorine is not a panacea, can only kill the conventional bacteria in the water, there is no role for some special bacteria. For example, in the United States found Legionella in water pipes, they have a strong chlorine tolerance. "Chlorine is not added, the safer the more chlorine and organic matter in water combined to produce disinfection byproducts, and most of disinfection byproducts carcinogenic, mutagenic characteristics, hazardous to your health, and the resulting effect is a chronic process, can not easily be found. "Four Cities water turbidity is doubled excessive" for the people, the turbidity is a very important sensory indicators, because this is something visible, can judge the water quality the most intuitive. "Zhao Feihong He said suspended solids in drinking water is generally clay, sand, fine organic and inorganic substances, plankton, microbes, colloidal substances. According to "drinking water health standards" (GB5749-2006) requirements, drinking water turbidity can not be greater than 1 degree. The test results showed that 89 water samples in 83 water samples meet the national standard, accounting for 93% of the total, of which 64 water samples turbidity is 0, that is not detected. If by city statistics, 29 cities in the 25 cities of the indicators qualified, accounting for nearly ninety percent of the total. "Turbidity also affect sterilization. The lower the turbidity, the better sterilization high turbidity, then bacteria, viruses can not easily be killed, because bacteria and viruses can drill down to these bulky than their suspension which is equivalent to provides them with a protection. "Zhansheng said suspension completely through the existing water treatment process to remove, if it proves excessive water treatment technology, however. Qi Cheng urban low fluoride content in accordance with "drinking water health standards" (GB5749-2006) requirements, the fluoride content in drinking water should not exceed 1.0mg / L. Effective in 81 water samples this test, the 77 water samples, the fluoride content of 26 cities in line with the national standard, accounting for 95% of the total number of water samples. Of course, there are four water samples exceeded the fluoride content. Two water samples Changchun fluoride contents were 1.9mg / L and 2.7mg / L, respectively, exceeding about twice, about 2 times; Yinchuan two fluoride content of water samples were 1.49mg / L and 1.29mg / L. "Fluoride has a great impact on people's teeth, there will be low levels of tooth decay, excessive levels will also affect the bones, especially on the larger development of children." Zhansheng said that China currently has more than 3,000 people Long-term excessive drinking water fluorine. The test results also showed that 81 effective water samples, the fluoride content of less than 0.5, there are 58, accounting for 72% of the total number of cities including Shanghai, Guangzhou, Shenzhen, Shenyang, Dalian, Ningbo, Zhengzhou. Among these, six fluoride content in water samples in Guangzhou, Hengyang, Harbin, Kunming four cities even to zero, that is not detected. The total number of bacteria exceeded "drinking water health standards" (GB5749-2006) requirements, the total number of bacteria in drinking water can not be more than 100, total coliforms are not detected. The test results showed that 5 water samples total number of bacteria, including Guangzhou, Xiamen, Chongqing, Yinchuan, including four cities exceeded. Among them, Guangzhou, a total number of bacteria in water samples was 250, the total number of bacteria in water samples and Xiamen are 160 and 180, the total number of bacteria in Yinchuan, a water sample is 358. The most serious is that Chongqing, the land of a total number of bacteria in water samples up to 1781, exceeding by nearly 17 times. Focus on water information, wealth, success in life!
