SIMULATION OF THE EFFECTS OF SALT SPREADING IN CHOSEN GROUNDWATER FORMATIONS

TIESUOLAUKSEN POHJAVESIVAIKUTUSTEN SIMULOINTI TYYPPIMUODOSTUMISSA

The spreading of salt is modelled in the chosen examples of groundwater formations. The formations are synthetic, but chosen to represent conditions representative of the Finnish groundwater formations vulnerable to this type of pollution. A nationwide risk-assessment study, in which several hundreds of groundwater formations were classified and analysed for their risk of pollution from highway salting, was used as a basis when determining these particular formations. The average steady state groundwater flow is determined in which the spreading of salt from the highway is then modelled. In prediction simulations to 2022 three different scenarios are studied: 1) salting will be continued at the high level of the early nineties (9,6 t/km), 2) no salt will be used, and 3) the amount of salt used will be reduced to about half of the high values (5.0 t/km). This study is part of a research programme investigating the potential contamination of groundwaters due to salt from highway de-icing.
