Background

The topic of water pollution is continuously raised, particularly the problem of underground water pollution, the surface water pollution is obvious, and the underground water pollution is regarded as a surprise. In 13 hundred million people in China, 70% of groundwater is drunk, and in more than 660 cities, more than 400 cities use groundwater as drinking water sources. But 90% of the municipal groundwater throughout the country has been described to be contaminated.

Yet another set of data also indicates that groundwater is facing significant challenges. In 2011, 857 monitoring wells in the district are evaluated to be 2% of the monitoring wells of I type and II type, while the monitoring wells of IV type and V type are up to 76.8% in 9 provinces and cities such as Beijing, Shanghai and the like.
