Many comprehensive surveys have been carried out on Samothraki Island aquatic resources (springs and streams) focusing on their chemical aspects.
Samples from 21 cold springs and 2 hot springs were examined for their physicochemical (water temperature, conductivity, pH and dissolved oxygen) and chemical (major ions and nutrients) characteristics. Springs were hydrochemically classified and evaluated considering the drinking water standards.
23 stream basins (45 stream sites) have been investigated in order to promote the interpretation of the factors and processes that determine their physicochemical and chemical characteristics. For this purpose, in situ measurements of physicochemical parameters were conducted and water samples were collected for laboratory analyses regarding major ions and nutrients. The chemical-physicochemical quality of the examined stream sites was assessed using the Nutrient Classification System (NCS) (Skoulikidis et al., 2006).
