Abstract

Background and Objectives: GROUNDWATER is one of the most important and worthiest resources of the country, which recognizing and optimal utilizing of these resources cause economics efflorescence. Inaccurate management and GROUNDWATER overdraft make irrecoverable damage to these resources, environment and economy of the country. Marand plain is one of the fertile plains of East Azerbaijan Province which 80 percent of its water demands is supplied by GROUNDWATER. Therefore, qualitative protection of GROUNDWATER resources of this Plain is vital. In this Study, Statistical Methods and Saturation Indices are used for assessment of quality parameters.Materials and Methods: The study area is located in the north west of east Azarbaijan province, some 60 km far from the Tabriz city. The total Marand area is 1871 Km2 which 589 Km2 of this area covers the Marand plain aquifers.48 water samples were collected from GROUNDWATER resources and analyzed and measured for major and some minor ions and species such as NO3-, F- and SiO2 as well as pH and EC in University of Tabriz hydrology lab.GROUNDWATER resources are separated by cluster analyzing in three distinct groups. In this research MULTIVARIATE ANALYSIS methods were used for quality parameters evaluation.Results: Cluster analyzing puts the water types in three individual groups. In first group the water type is bicarbonate sodic and in second and third groups it is chloro sodic type. The results of factor analysis indicated that three factors such as salty geologic formations dissolve of minerals and increasing of evaporation control about 75% of the total samples variance. To identify geochemical processes governing to the aquifer, saturation indices of calcite, dolomite and gypsum of the samples were evaluated. The results showed that chemical composition of GROUNDWATER is highly affected by river recharged water, aquifer skeletal materials and evaporation from the GROUNDWATER.Conclusion: The results showed that the quality variations of GROUNDWATER is affected by salty evaporate formations, solution of minerals and aquifer materials, evaporation from the rivers waters which recharge to the aquifer, water and formation reactions and evaporation from the GROUNDWATER. Also, the results showed that the water quality for agricultural, drinking and industrial purposes in eastern and southeastern parts of the study area is more suitable than the north and northwestern parts of the plain.
