Beginning in 2004, geological surveys have been underway in the Jadar River valley, focusing on the study of the area's hydrogeological characteristics. To facilitate this, piezometers have been deployed. Employing piezometers is a widely accepted technique for observing groundwater levels, and they also enable the collection of groundwater samples for chemical analysis.

In the Jadar Valley, piezometers are categorized into shallow or deep, primarily distinguished by the depth at which they monitor groundwater.
The initial set of 'shallow' piezometers serves to track fluctuations in the level and quality of shallow groundwater within the Jadar and Korenita valleys. Being near the surface, this water typically meets the standards for general household use, though its bacteriological profile makes it unsuitable for drinking. The 'deep' piezometers are designed to observe groundwater in the terrain's lower strata, exceeding 600 meters beneath the surface, where the water is generally under pressure.
Throughout the studies conducted to date in the Jadar Valley, a total of 176 piezometers have been installed. Among these, 51 are categorized as deep, while the remaining 125 are considered shallow, positioned at depths less than 30 meters.
Each of these structures has been installed in compliance with legal and professional procedures. The piezometers are equipped with a protective cap or cage under which automatic water level and pressure gauges are located. Contracts for the lease of land have been concluded with all landowners where the piezometers are located.
In recent period, 8 holes being closed, in accordance with the expiration of the lease agreements for mentioned holes.
Piezometer Monitoring
Piezometers undergo periodic inspections and maintenance checks to promptly address any technical issues that could result in leaks. Upon detecting any faults, the geological team swiftly undertakes the necessary repairs or replacements of the faulty equipment.
The most recent evaluation of the piezometers within the Jadar region took place from February 26th to 29th, 2024. This comprehensive review confirmed that all piezometers were functioning correctly, with no water leakage detected at any of the surveyed locations.
