With economic development and continuous population growth, groundwater has been over exploited and the groundwater level depth declines significantly, and the over-exploitation resulting environmental and geological problems. In order to realize the scientific management and rational planning of groundwater, we develop a new groundwater information system. Some key technical issues such as data acquisition, transmission, management and remote control can be solved by the system. Moreover, we can use the system to analyze real-time monitoring data, synchronously update data, display, query, manage apparatus device and communication equipment (including the information of monitoring well), give an alarm and so on. The system is compatible with a variety of equipment and the monitoring data with different formats can be also processed by the system. Users can access this system via Internet, so the system is of good convenience and high versatility.
