The research area of this study is the city of Khorramabad . The data of this study are 23 wells and springs in Khrorramabad and from 1381 to 1392, which is seasonal. Information and data on the chemical elements present in the water parameters: ph., total hardness (TH), electrical conductivity (EC), Total Dissolved Solids (TDS), sulfate (SO4), chlorine (Cl), nitrite (NO2) and nitrate (NO3). . The results showed that Ph. of all wells and springs allowed within acceptable limits and standards. The total hardness (TH) is higher than the desirable standards in all seasons in all of resources and is lower than the allowed maximum of standards. According to the conducted researches, the amount of the electrical conductivity, total dissolved solids (TDS) and sulfate (SO4) are lower than optimum and maximum in all wells and springs in all seasons. The amount of chlorine (Cl) in all wells and springs is lower than the limit on the number of allowable standards but is higher than the desirable standard of EPA. In all seasons the amount of nitrate (NO3) on all resources is lower than the allowed Iranian national limit, and desirable and permissible World Health Organization (who), and the limit of EPA standard, but in all of the resources is higher than the desirable limit of (EPA). Also, in all seasons, the amount of nitrites (NO2) in all wells, springs and the study area is lower than the standards.
