What is groundwater monitoring?

Groundwater monitoring is the process of measuring parameters such as extraction flow, water level, and water quality in deep wells, located from several tens to several hundred meters below the ground.

Why is continuous, automated groundwater monitoring necessary?

"Continuous automated groundwater monitoring" not only helps investors optimize production processes and control extraction flow but also allows them to proactively arrange production plans and comply with government regulations on the management and use of groundwater resources.

What parameters are needed for well monitoring?
According to Circular 47/2017/TT-BTNMT on monitoring the exploitation and use of water resources by the Ministry of Natural Resources and Environment, the parameters to be measured may vary depending on the monitoring program's goals. Some basic parameters include:

• Water level at monitoring points (boreholes, dug wells)

• Flow rate at monitoring points (outcrop points, spring points)

• Environmental water parameters such as: physical properties (color, odor, taste, turbidity), pH, electrical conductivity (EC), dissolved oxygen (DO), redox potential (Eh or ORP), alkalinity, salinity, etc.

Data from the main data logger will be transmitted to the control room at the plant for 24/7 internal monitoring and transmitted to the Department of Natural Resources and Environment via a static IP Internet connection, using the FTP method and in .txt file format, meeting the requirements of the Department of Natural Resources and Environment.

The groundwater monitoring system consists of two main parts:

1. Flow and water level measurement equipment installed at each well.

2. Data transmission system including local data loggers placed at each well.
