      Electrical Conductivity (EC) and Total Dissolved Solids (TDS) are important factors in the surface and subsurface water researches. Usually, EC and TDS are low in wet season and high in dry season. Investigation in groundwater of Tasuj plain shows that some of groundwater samples have reverse presentation that mentioned above. Four factors were distinguished that may be effective in this case are: 1) effect of geological formation diversity, 2) local groundwater pollution (industrial, domestic and urban agricultural and deicing), 3) artificial recharge effect and 4) measurement errors. In respect to available information and specific position of the plain, two former factors are very effective and third factor effect is not distinctive exactly and finally forth factor is not important.
