Water Chemistry of Samos Project

The project is carried out by Xinhao Li, Zehao Jin, Feng Chen and Shuangcheng Li under supervision of Prof. Dr. Christoph Külls. The aim of the project is to describe the water chemistry of the Heraion plain on Samos.

The HCO₃^- results which got separately from direct calculation, Aqion and Phreeqc are shown as follow. There might be some problem with WK007, and WK021 WK024 and WK025 are probably sea water.

Group 1

Members:
 1.surface water WK015.028.010 
 2.groundwater type2 WK014.019 
 3.groundwater Wk006.008.023.026.016.005.011
 4.spring WK017 

This group mainly consists of 2 types of groundwater and few other types 
like 1 surface water and 1spring. They all have high Ca2+ concentration 
and lower Mg2+ and Na++K+ concentration. For anions, CO32-+HCO3- is higher, 
CI-+NO3- and SO42- are lower. 

Group 2

Members:
 1.sea water WK024 
 2.salty groundwater WK025 

Na++K+ pretty high, Mg2+ low, Ca2+ super low
CI-+NO3- are considerably high, SO42- is low, and CO32-+ HCO3- are nearly zero.

Group 3

Members:
 1.spring WK018
 2.salt lake WK022 

These two both have a nearly equal concentration of Na++K+ and Ca2+, 
Mg2+ is much lower compared to them.
CI-+NO3- and CO32-+HCO3- are also nearly equal, and SO42- are lower.
But Mg2+ and CI-+NO3- are slightly higher in salt lake than spring.
We predict these are probably a mixture of group 1 and group2. 

Group 4

Members:
 1. heraion WK001.003.004.029

Heraion plot in those areas with low Ca2+ low Mg2+, high Na++K+, 
high CI-+NO3- low CO32-+HCO3- and low SO42-. 
They might be some mixture of group1 and group2 or group3 and group3, even all of 3 groups.
