In Eastern Europe, around 23 percent of stations show increasing trend with the groundwater. This might be related to the decrease of pressure on groundwater resources due to population decrease in past decades (EEA, 2019 – CSI 018). Furthermore, observed increases in precipitation may play a role (EEA, 2017 – CLIM 002). The increasing groundwater level may lead to an increase in flood risks, damaging public infrastructure and basements of buildings. In addition, it may cause plant oxygen stress resulting in reduced crop yields because of causing plant oxygen stress. On the other hand, if initial groundwater levels were low, an upward trend can also have positive consequences, such as the replenishment of aquifers.

Increasing GW levels can also lead to solution effects in subsoil causing GW quality problems.
Thank you for your comment. Based on your suggestions we edited this paragraph and included solution effects and groundwater quality problems: “….causing plant oxygen stress. In addition, it can lead to solution effects in the subsoil causing groundwater quality problems. On the other ….”

It should be recalculated with using the same units.
