According to the collected data by TRWB in the city of the Tehran, from 1987 to 1991, ground water plain was studied and divided into two regions, the areas were called highly contaminated and low contaminated areas.

Beside the pollution problem, because of the substantial quantities of water transmitted from Karaj, Lar, and Latian dams, cause a rise in the groundwater table. This rise in groundwater table makes serious prolems. Studies on groundwater quality showed that the central pa
