Background technique

Groundwater refers to the water that exists in the rock voids below the ground. In a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. Groundwater is an important part of water resources. Due to its stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as swamping, salinization, landslides, and land subsidence. The detection of groundwater is also very important, and sampling and testing of groundwater sources is required. Most of the existing sampling equipment places the sampling tube in the water and sinks it to the location where sampling is required to sample the water source.
