Title

HYDROGEOCHEMISTRY OF GROUND WATERS IN GORGAN PLAIN: AN IMPLICATION FOR GROUNDWATER CONTAMINATION SUSCEPTIBILITY

Pages

  1-10

Abstract

 Gorgan Plain with an area more than 5000 km2 is located in the southeast of Caspian Sea. Since groundwater is the major source of water for domestic, industrial and agricultural uses in the area, it is necessary to ensure GROUNDWATER QUALITY by protecting them against pollution sources. In this study, hydro geochemical data from 96 irrigation wells were used to evaluate water quality and to determine processes that control water chemistry. The samples were classified into five groups (I, II, III, IV and V) according to their geochemical characteristics using cluster analysis. The results indicate that the GROUNDWATER QUALITY and geochemical characteristics of clustered samples are consistent with the geology and hydrography of the area. Samples collected from the area close to the recharge points which had been covered with gravels and sands were clustered into group I. The amounts of parameters such as pH and TDS as well as the concentration of HCO3 and SO4 in area which had been covered by silty soils were higher as distance from the recharge points increased (groups II and III). The highest concentrations of chlorine and sulfate belong to the northern parts of the study area (groups IV and V), which is mainly covered by fine grain sediments of clay. Spatial distribution of the statistical groups showed that the samples from each group are in close proximity to one another suggesting the same processes and/or flow paths. Overall, the results showed that groundwater clustering based on water chemistry could be applied to the contamination susceptibility assessment for ground waters in different areas.
