The impact of horizontal geothermal systems on groundwater temperature has not been studied in detail due to their generally shallow installation depth. However, interactions between very shallow geothermal systems and groundwater are expected, especially at short groundwater distances. In this study, the effects of a large-scale geothermal collector system (LSC) in Bad Nauheim (Hesse, Germany) on the downstream shallow groundwater were analysed. For this purpose, subsurface and groundwater temperatures were measured over a period of two years. The results showed that in the immediate downstream area, the maximum degree of cooling of the groundwater temperature was between 4.2 and 5.2 K with a minimum temperature of 5.2 °C. Consequently, the presence of a temperature plume was demonstrated, whereby a significant regeneration of the subsurface temperature in comparison to measured values within the LSC area was also observed.
