     groundwater is the only major source of water for drinking, agricultural and industrial usage in the kamrud region in north semnan provence and its vital importance causes to serious concerns about groundwater quality. in this study data from water wells at two sampling periods (spring and summer) were used to evaluate factors and processes which are effective on groundwater hydrogeochemistry. three effective factors extracted by multivariate statistical analysis on mixture groundwater. according to the cluster dendogram, between hco3-1 and mg+2 is maximum similarity. bicarbonates are determined as main groundwater type with due attention to piper diagram and result of correlation matrix. iso conductivity, iso total dissolved solids and pie chart hydrochemistry maps show that ec, tds and cl are increased in the northeastern part. spatial interpretations of the parameters changes in groundwater indicate that samples quality and geochemical characteristics are mostly consistent with the topography, geology and hydrography of kamrud plan. samples which belong to the southern parts of district have acceptable quality but groundwater quality in the northeastern part is different because of increasing dissolves concentration and existence of more fine grain sediments. overall, agents including flow direction exceed of water table and human activities in the northeastern part make this part vulnerable to unusual contaminant sources (urban wastewater influence, etc).
