Abstract: The augmentation of human population, agricultural activities, and the over-exploitation of groundwater resources, along with the climate change are contributed not only to the reduction of available water reserves but also to the groundwater quality degradation in the Mediterranean region. The prevention of groundwater pollution is imperative especially where the aquifer is more vulnerable to contamination (Kazakis and Voudouris, 2015) and where there is water scarcity in irrigated and cultivated areas as in the Thessaly region (Loukas et al., 2007; Mylopoulos et al., 2009; Sidiropoulos et al., 2021). In this study, an attempt is made to assess the vulnerability of the aquifer of the catchment area of Lake Karla in Thessaly, Greece, with the DRASTIC method (Aller, 1985). The DRASTIC model combined with Geographic Information Systems (GIS) have been used to identify the vulnerable zones of the Lake Karla aquifer system.
