The scaling potential of groundwater in southeastern Norway

Abstract

The degree of saturation of groundwater with respect to a wide range of solid phases is calculated for 240 private and public bedrock wells in Akershus and Østfold counties, southeastern Norway. The samples were collected by the local Næringsmiddeltilsynene (Public Hygiene Control Office) in cooperation with the Geological Survey of Norway (NGU). The chemical analyses of the collected samples were carried out at NGU Laboratories as a part of the project \"Landsomfattende kartlegging av kjemisk kvalitet i grunnvann i fast fjell\" (\"Country-wide mapping of the chemical quality of groundwater from bedrock aquifers\") during 1997, and are found in the NGU-reports 97.157 and 97.158. \rFormation of precipitates (also referred to as \"scaling\") on filters andpumps in groundwater wells, is a common problem in many areas of the worldwhere groundwater is used as drinking water. With rising energy costs there will be an increased demand for using alterntive energy sources heat. (Forkortet)
