Abstract

Chahderaz plain aquifer provides 25% of required fresh water of Golgohar mining Industries. The problem of the aquifer is salinity increasing that appears in all 8 wells of the Golgohar mine in the plain since next 20 years. The salinity is enhanced from TDS=800ppm, in 20 years ago, to 5966ppm now. The first reason of the salinity increasing is drought of this region that causes unbalancing between the precipitation and the evaporation rate of the plain. But both quantitative and qualitative groundwater models of the plain illustrate traditional method of flood irrigation in the pistachio fields of the plain can increase 44703ppm the TDS of the aquifer during next century. The models predict if artificial recharge project (Arc Percolation Tank) develops on the plain, the TDS increasing of groundwater would not exceed more than 2693ppm during the same period. This method can recognize as a long-term solution of quality assurance of each groundwater that need to remediation; the reason that made Golgohar Mining and Industrial Company totally accept the cost of implementing this project.

Keywords: Golgohar mine; Arc percolation tank (APT); Remediation; Salinity
