Road Salt and Environmental Hazards—Identification of Vulnerable Water Resources

Abstract

The Norwegian Public Roads Administration (NPRA) just finished a four year research and development project, entitled: ``Salt SMART''. The objective has been that the NPRA's effort to maintain ease of passage and traffic safety during winter, shall not result in unacceptable effects to the environment. To solve this, areas vulnerable to road salt within Norway has been identified. In this paper, a flowchart method to identify water resources vulnerable to road salt has been presented. Readily accessible data or methods, produced in the Salt SMART project have been used. The results have been processed and presented in a GIS (Geographic Information System).
