==== Hydrogencarbonate results ====



The HCO<sub>3</sub><sup>-</sup> results which got separately from direct calculation, {{ :en:projekte:aqion_wk001-029.zip |Aqion}} and {{ :en:projekte:phreeqcwk001-029.zip |Phreeqc}} are shown as follow.
There might be some problem with WK007, and WK021 WK024 and WK025 are probably sea water.

==== Summary of diagrammes ====

{{ :en:projekte:analysis.docx |}}

**Group 1**
<code>
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. 
</code>

**Group 2**
<code>
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.
</code>

**Group 3**
<code>
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. 
</code>


**Group 4**
<code>
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.
