This review paper is focused on groundwater level monitoring, long-term groundwater level data and data visualization. The level logger (or telemetry) provides an inexpensive and convenient method to measure level, temperature and conductivity salinity all in one probe. It can provide real time view as data is being recorded by the connected data logger. Water-level measurements from boreholes are the principal source of information about the groundwater recharge, storage, and discharge. Long-term and systematic measurements of water levels provide essential data needed to evaluate changes in the resource over time to develop groundwater models, forecast trends and monitor the effectiveness of groundwater management. A significant advantage of this method of data collection and reporting is the groundwater level data can be updated real time. By using GIS, the dataset of water level can be visualized to understand the relationship between locations of borehole relative to topographic, geologic, or hydrologic features. GIS and the internet greatly boost the capability to deliver an interactive water level data to potential users. All of these features are presented along with graphical evidence of the deployment of the different devices and of several cellular communication and on-site data acquisition tests.
