The deterioration of the natural environment and the discharge of pollutants have a direct impact on the lives and health of local people. China's tap water safety standards have not only failed to catch up with foreign standards for direct drinking, but even the most basic water sources have been contaminated in ways that should not be underestimated.
In 2011, industrial water pollution accidents were frequent across the country
In April this year, about 600 tons of tetrachlorosilicon tetrachloride waste liquid entered the city's sewage treatment plant in large quantities through the urban drainage network of Zhongxiang in Jingmen, Hubei province, leading to paralysis of the plant for more than two months, and the city's production and living sewage backed up to the moat in a stinking manner.
Also in April, Dafeng City, Jiangsu Province, Xinfeng Town, Red Flag Village, part of the masses due to discomfort to the health center, the cause of illness is suspected of villagers drinking tap water contamination. Dafeng municipal party committee, the county government received the report attaches great importance to immediately start the emergency plan. Investigation team's preliminary conclusion: the supply of red flag village, the second, third, fourth villagers group area of tap water by chemical and biological contamination. The preliminary conclusion of the cause of pollution: in early April the region's upstream water pipeline due to tree-planting excavation led to a number of multiple ruptures, coupled with the town's water plant to take the intermittent water supply method, resulting in sewage seepage into the water pipe.
On May 17, water pollution in Shanhe Township, Wuchang City, Heilongjiang Province, caused dozens of children to vomit, diarrhea and other adverse reactions. As of 20:00 on the 23rd, 95 people have realized that they have symptoms. Cases are mainly concentrated in Shanhe town center elementary school, Shanhe town kindergarten, Shanhe town school for the deaf and nearby residents. As of 17:00 on the 24th, there are still 26 children in the hospital to receive infusion treatment. 25, tap water contamination of the two pipeline leaks repair is completed, the return to normal water supply.
On the evening of June 4, a traffic accident occurred in Jiande City, Zhejiang Province, and some of the phenol leaked from the filling truck flowed into the Xin'an River. Due to heavy rainfall in the region, some of the leaked phenol flowed into the Xin'an River with surface water. As the Xin'an River is located in the upstream of Hangzhou's important drinking water source, it has a significant impact on the normal production and living water of downstream residents.
On June 20, Huazhou City, Guangdong Province, Xin'an Town, Longtan Village Committee lion ridge of Huazhou City, Deying Kaolin Factory long-term illegal discharge of untreated acidic wastewater, resulting in the local Longwu River and Li Miao Kuwan water pollution. Monitoring data show that, as of the evening of the 20th, the Longwu River and Li Miaokou Bay water quality pH value has risen and meet the standards, its downstream drinking water source Chedi Reservoir water quality is not abnormal, the monitoring section of the water quality reaches or better than the surface water Ⅲ standard.
Recently, the frequent occurrence of water pollution incidents in many areas has caused people to think y about the causes. According to the information provided by the relevant state departments, from the direct aspect alone, there are five main reasons: First, the total amount of water pollutants discharged remains high, water pollution is quite serious. According to the environmental protection department monitoring, in recent years, the country's seven major water systems, 411 surface water monitoring section of 27% of the section for the inferior V water quality, the country about 1/2 of the urban area of the city's groundwater is seriously contaminated, and some areas have even appeared, "there are all dry river, there are all the water is polluted," the phenomenon. Secondly, the development and utilization of water resources in some basins is too high, exacerbating the deterioration of water pollution. According to the latest "Water Resources Survey and Evaluation Results", the utilization rate of Huaihe River is 53%, the utilization rate of Liaohe River is 66%, and the utilization rate of Haihe River is 100%, which leads to basically no ecological flow in the dry season of these rivers, greatly reducing the self-purification ability of the basin water body. Third, the safety of drinking water for urban and rural residents is a great danger. According to the environmental protection department, the national 113 key environmental protection city of 222 drinking water surface water source of the average water quality standard rate of only 72%, many areas of the water source is shrinking trend, more than 300 million rural population of drinking water safety problems. Fourth, water pollution accidents occur frequently. The number of water pollution accidents accounted for about 49.2% of the total number of environmental pollution accidents. Fifth, the cost of compliance is high, the cost of violating the law is low.
The development of water pollution prevention and control of the new situation, the need to further improve the existing legal responsibility, increase penalties.
