Evaluation of Potable Groundwater Quality Using Environmetrics. The case of Nestos and Strymon River Regions, Northern Greece

In the present study potable water samples were regularly collected from two geographical regions in Northern Greece. The two regions are close to the Nestos and Strymon Rivers. Throughout 2015, samples from 13 sites were collected and analyzed with a frequency of three times per each quarter for the following parameters: chloride, calcium, nitrate, potassium, electric conductivity and total hardness. The main objective of this study was to investigate the effects of the geographical region and seasonal influence on the above parameters regarding the limits of the 98/83/EC Directive. The findings of the Linear Mixed Effects modeling revealed statistically significant main effects of both factors on the examined parameters. © 2021 School of Science, IHU. All rights reserved
