Yet, if pollution transport pathways can be found, then contamination level can be detected with fewer samples. In this case study, pollution levels at an abandoned coal mine site at Ovacik-Yaprakli (Cankiri, Turkey) is evaluated with respect to topography and surface runoff pathways derived using Geographical Information System (GIS) tools
