The impact of geothermal systems on groundwater and development of protection measures water protection requirements for water intakes

The purpose of the study is to map new technological possibilities and determine criteria for the construction and use of different types of vertical geothermal systems, to carry out experimental tests to assess the impact of these systems on the quality and temperature of groundwater, and to provide input for changing water protection requirements in legislation using new knowledge. The research activity also increases knowledge about groundwater as a carrier of ground heat for the purpose of its economic use and the thermal conductivity of different rock layers. The target group of the study is the designers of vertical geothermal systems, builders, drilling companies, drafters of various plans, local governments, Environmental Board, Environmental Agency, Geological Survey of Estonia, private persons, renewable energy specialists, heat pump installers.
