Applying Factor Analysis and the CCME Water Quality Index for Assessing Groundwater Quality of an Aegean Island (Rhodes, Greece)

Globally, water quality indices (WQIs) are beneficial for evaluating groundwater and surface quality. The Canadian Council of Ministers Environment Water Quality Index (CCME WQI) was combined with the parametric values given by Directive 98/83/EC to investigate possible suitability resources human consumption on Rhodes Island. Chloride (Cl?), pH, calcium (Ca2+), electrical conductivity (CND), carbonate (CO32?), bicarbonate (HCO3?), potassium (K+), magnesium (Mg2+), sulfate (SO42?), sodium (Na+),nitrate (NO3?), nitrite (NO2?), ammonium (NH4+), phosphate (PO43?) were included in dataset applied this study. Statistical analysis, GIS database, WQI estimation successfully used evaluate study area. All studied parameters have mean median lower than corresponding established 98/83/EC. high CND (up 2730 ?s cm?1) collected from Rhodes’ coastal aquifers indicate a direct relationship seawater intrusion. CCME-WQI classifies samples most monitoring stations as “excellent”, Class 5, 2019 2020. findings may be helpful scientists stakeholders area applying measures protect resources.
