NGU has conducted a hydrogeological assessment of a groundwater well which Best Kjøttprodukter AS is considering for the production of bottled water. This report forms the basis for approval by the local Food Control Authority to use the well for the production of bottled water. The hydrogeological assessment of the groundwater well is based on geological- and environmental mapping of the area, as well as test pumping of the well with an extraction rate of 1 l\/s during a period of one whole year. In conjuction with the testpumping, monthly water samples were extracted for microbiological-, chemical- and physical analyses. The results show that the groundwater has a good and stable quality that meets all microbiological- and esthetic requirements of the Directive for extraction and production of natural mineral- and spring water and the Directive for water supply and drinking water. The geological mapping demonstrates the bedrock well protected from surface water and potential contamination in the vicinity of the well area. To further protect the well from potential contamination, protection zones have been estalished around the wells where restrictions of activities have been imposed. Based on all studies conducted, NGU assess this groundwater well to be well suited for the production of bottled water.
