The Use of Artificial Tracer Tests in the Process of Management of Karst Water Resources in Slovenia

Abstract

Tracer tests with artificial tracers are one of the most useful research techniques in karst hydrogeology. Traditional use of tracer tests in Slovene karst dates back to the end of the nineteenth century. Tracer tests are especially useful for solving specific environmental or engineering problems. They are also increasingly recognized by administrative and management bodies as being useful for management of karst water resources. This chapter provides a brief review of applications of tracer tests: (1) for designation and validation of water protection zones, (2) for planning the water quality monitoring in the impact areas of pollution sources, and (3) for assessment of the threats to karst water sources from traffic. Several examples of best practices are presented, along with study results and suggested guidelines for future development. Finally, an initiative for developing a shared database of tracer tests is introduced. The goal of the database is to compile the results of previous tracer tests within a template that would enable fast and easy data access.
