Groundwater at the country’s border is of good quality, concluded geologists


Based on the data of the Lithuanian Geological Survey (LGS) under the Ministry of Environment, there is good-quality groundwater at our country’s border with Belarus, Poland, and the Russian Federation. This fact is confirmed by the results of the monitoring carried out on these sites.

The country shares the longest border with Belarus, i.e. 677 kilometres. The north-eastern border section falls within the territory of the Dauguva River Basin, whereas the larger border section is located within the territory of the Nemunas River Basin. Groundwater monitoring is carried out within the selected 10–20 km strip. For this purpose, special wells (two in Belarus and seven in Lithuania) and groups of wells (two in Belarus and thirty one in Lithuania) were drilled. Monitoring is also conducted in production wells of small waterworks (one in Belarus and ten in Lithuania). According to Jonas Satkūnas, Director of the LGS, the monitoring results show that more than half (56 per cent) of the wells situated in this border section contain very high-quality groundwater, whereas groundwater in 26 per cent of the wells is of good quality, and groundwater of a poor quality was found only in 18 per cent of the wells.

Good-quality groundwater is also found by the border with Poland. Here monitoring has been carried out for more than 20 years. There are 15 monitoring stations operating at Lithuanian border. They cover 22 wells.

The LGS monitors the quality of groundwater in the selected monitoring stations and at the border with the Kaliningrad Oblast of the Russian Federation. Here, the Lithuanian monitoring network consists of 11 wells under natural conditions and 8 wells in small waterworks. Based on the monitoring data, groundwater in this border region is of good quality as well.
