At present, the quality of drinking water sources in the Pearl River Basin is very worrying. Water quality in some rivers, which bear the main water supply function, is declining, and the water quality standard of urban drinking water sources is low. This is the 9 held in Shenzhen in 2005 "Pearl River Basin Water Resources Protection Conference" on the information disclosed by experts.
How dirty is the water in the Pearl River? According to the relevant data, in 2004, the total amount of waste water discharged from the Pearl River was 182.7 tons, of which 139.5 tons of waste water were discharged into the river, while the amount of waste water discharged from the Pearl River Delta accounted for 52% of the total amount - it was really a frightening jump. So, who messed up our drinking water? Monitoring shows that the Pearl River estuary water area of nearly 6000 square kilometers of heavy metals in water, inorganic nitrogen and oil almost 100% exceed the standard, the water pollution index of Lingdingyang in most area has reached the level of heavy pollution in coastal waters, inorganic nitrogen more than four water quality standards, the nutrient salt imbalance...... Obviously, this is mainly the enterprise pollution made sin.
Chinese is a serious water shortage in the country, but the precious and limited water resources, but the majority are suffering from serious pollution threat, experts say, this problem has become one of the major challenges of the next twenty years China well-off society facing the Pearl River water pollution can be said is a good example. The situation is so dire, if we don't resorted Henzhao, penetration of water pollution this problem, so, maybe tomorrow, maybe the day after tomorrow, we have no clean water to drink, this is not alarmist!
