Special wells proliferate to monitor groundwater

To better conserve groundwater resources, more professional monitoring wells that can test water quality have been set up across wider areas of China, the China Geological Survey, an institute under the Ministry of Natural Resources, said at its annual conference on Wednesday.

By the end of last year, the number of monitoring wells nationwide had risen to more than 10,100 compared with 5,100 in 2017. And 93 testing indexes for groundwater have been added to monitoring results, according to the CGS.

Li Wenpeng, senior engineer at the CGS, said that previously they had often used local residents' monitoring tools, but now their own tools are more professional and evenly distributed across the country.
