Country witnesses rising number of drilled wells2017-01-05
According to information of the Lithuanian Geological Survey (LGS) under the Ministry of Environment, during the recent five years the country has witnessed the growing number of drilled wells annually. Last year, the LGS Register of the Underground registered 1 523 new drilled wells or by 65 wells more than in 2015.
Almost all of the drilled wells (1 456) registered in 2016 are intended for water extraction. By the beginning of this year, a total of 35 835 operating drilled wells had been entered in the Register of the Underground. Most of them have the purpose of groundwater extraction.
Non-used drilled wells have to be removed. Inappropriately installed, non-removed or abandoned drilled wells are potential sources of pollution that can enter groundwater. To protect an operating water extracting site from pollution, a buffer zone of the water extracting site regulating the economic activities around a drilled well must be established.
Removed drilled wells can become obstacles to mining operations. Therefore the State Geological Survey information system contains data on all drilled wells that have ever been installed for extractive or exploratory purposes. The data on drilled wells are used to produce state geological and hydrogeological maps and study the structure of the underground.
