Abstract：In order to implement the national groundwater monitoring project and the groundwater quality monitoring task, and to realize the effective monitoring of groundwater dynamics in West Liaohe Plain, 117 national automatic groundwater monitoring wells have been set up in West Liaohe Plain in the national groundwater monitoring project, including 93 new monitoring wells and 24 reconstructed civil wells, and 117 sets of automatic monitoring instruments have been installed. The controlling area is 57 000 km2, and the pore water aquifer of Quaternary loose sediments is the main groundwater monitoring horizon,with the maximum depth of 206 m. The national groundwater monitoring project information service system has been established, which has enhanced the ability of acquisition, analysis, sharing and serving of the groundwater monitoring information. The implementation of this project has greatly improved the frequency, timeliness, reliability and accuracy of groundwater monitoring in the monitoring area.
