At present, the water quality of drinking water sources in the Pearl River Basin is very worrying, and the water quality of some rivers that are responsible for the main water supply is declining, and the water quality of urban drinking water sources is low. This is the 9th held in Shenzhen "2005 Pearl River Basin water resources protection work conference", related experts revealed the information.
How dirty is the Pearl River water? According to relevant data, in 2004, the total amount of waste sewage discharged in the Pearl River was 18.27 billion tons, of which 13.95 billion tons of waste sewage was discharged into the river, and the waste sewage discharge in the Pearl River Delta accounted for 52% of the total. So, who is polluting our drinking water? The monitoring shows that almost most of the heavy metals, inorganic nitrogen and petroleum in the nearly 6,000 square kilometers of water bodies in the Pearl River estuary exceed the standard, the water quality comprehensive pollution index of most of the waters in the Lingdingyang reaches the heavy pollution level, the inorganic nitrogen in the coastal waters exceeds the four types of seawater water quality standards, and the proportion of nutrients is seriously unbalanced. Obviously, this is mainly caused by corporate pollution.
China is a country with severe water shortage, but most of its precious and limited water resources are under serious pollution threat. Some experts say that this problem has become one of the major challenges facing China in the next two decades to build a well-off society in an all-round way, and the pollution of the Pearl River waters can be said to be a good example. The situation is so serious that if we do not take drastic measures now to tackle the problem of water pollution, then maybe tomorrow, maybe the day after tomorrow, we will not have clean water to drink. This is not an alarmist.
