Groundwater Joint Field Surveys in Caucasus Countries, April-May 2015

On 20 April - 8 May 2015 the 2nd groundwater joint field survey was carried out in the pilot river basins of Armenia (Akhuryan-Metsamor), Georgia (Chorokhi-Adjaristskali) and Azerbaijan- (Central Kura).
The purpose of the field surveys was different in the pilot basins:
Armenia – to map areas of elevated arsenic concentrations;
Georgia – to check groundwater quality (trace elements) in main production groundwater bodies;
Azerbaijan – to inventory existing groundwater monitoring network.  
10 representative groundwater samples have been collected from each pilot basin and will be analysed in the national labs for trace elements required by the WFD and GWD: copper (Cu), lead (Pb), zink (Zn), nickel (Ni), chrome (Cr), cadmium (Cd), antimony (Sb), aluminium (Al), arsenic (As) and sodium (Na). Five control samples for the same elements from each pilot basin will be brought to the accredited lab in Vilnius, Lithuania.
Coordinates of sampling points were fixed with the GPS MAPS 62sc device.  Some chemical parameters (temperature, pH, electric conductivity (EC) and total dissolved solids (TDS) have been measured in the field at the sampling point. In Georgia also oxygen concentrations were measured.
