Yazd – Ardakan Plain located at the Iranian Center.Most of the population in Yazd Province located at the this plain So Temporal and spatial Groundwater Quality is necessary to study.In order to study groundwater quality variations we drew on the Thirty groundwater samples fromYazd Regional Water Authority related to Yazd Ardakan plain 2002-2010 using Simple Kriging were collected and analyzed for EC , TDS and SAR. Considering this Research results, Groundwater Quality in Yazd – Ardakan Plain has been found to decrease from South West and West to North, North East and East. The reason for this subject is Neogene formations in the East and Salt Desert SIAH KOH Margin in the North. Maximum average indicators EC , TDS and SAR Respectively in the years 2002, 2007 and 2002 occurred and Minimum average indicators EC , TDS and SAR Respectively in the years 2003, 2003 and 2009 occurred. Seems to be the trend of the three indicators follows of groundwater fluctuation model and drought. The three parameters studied between the years 2005 to 2007 Upward and then to have downward.
