Soil leming as a measure to improve acid groundwater

Abstract

Fourteen catchment areas of wells with acid groundwater were limed with rather high dosages of calcium carbonate, ranging from 1.6–5.0 kg m^‐2. Three to four years after liming the drinking water of three wells gives a clear indication of the treatment. In two recharge areas the soil chemistry were intensively studied and the base saturation has increased to a depth of 60–70 cm from the surface. The ion balance has changed in the soil layers and a transport of base cations seems to be going on towards the groundwater.
