The chemical analysis of 9 water wells in Razgah area,
Azarbaijan province NW of Iran has been evaluated to
determine the hydrogeochemical processes and ion, heavy and
rare metal concentration background in the region. The
dominated hydrochemical types are Na+Cl in area. The metals
often concentrate in south and western part in study area.
Due to geological conditions and water flow path in the
region, probably due to increased metals in the western and
southern parts of the area is Razgah intrusion. Based on the
total hardness, the groundwater is very hard. According to
EC and SAR the most dominant classes are C4-S4. The major
ion concentrations are above the acceptable level for
drinking water. The groundwater salinity hazard is very high
and Na hazard is very high and in regard of irrigation water
the quality is low. So the drainage system is necessary to
avoid the increase of toxic salt concentrations.
