Generalised hydrogeological map of Lower Saxony, 1 : 500 000 - Groundwater quality - Potassium
(HUEK500GWB_K)
The generalised hydrogeological map of Lower Saxony, 1 : 500 000 - Groundwater quality: Potassium content, shows the evaluation of a representative sample of potassium concentrations taken from the LBEG laboratory database. The data collected in the period 1967-2000 were averaged twice. Where groundwater monitoring wells were subject to multiple analyses, the averages of the available analysis results were formed. In addition, the data from all sampling wells in a 2000 m radius were averaged again.
Increased concentrations which are obviously caused by point-source anthropogenic inputs (e.g. potash production facilities), are not included in these generalised maps. The potassium levels are shown in depth stages without reference to the local hydrogeological situation. The data therefore cannot be compared without taking the respective hydrogeological situation into consideration (e.g hydrogeological layering), nor can the data be adopted for detailed investigations.
Considerable quantities of potassium are released locally during the production and processing of the potassium compounds. For example, both surface and groundwater in the vicinity of operating potash production facilities often contain increased anthropogenic concentrations. Widespread input results from the use of potash fertilisers. Fertilised soils on agricultural land often lead to increased groundwater potassium levels.
