ABSTRACT
Our study achieved in AL-Najaf province within kufa district which are consist of
stream network, in dry season (2016), there are thirteen samples collected and six
physicochemical parameter analyzed in laboratory of environment in surface water
and agriculture directorate in AL-Najaf Province. Six physicochemical parameter
like Ec (mmho/cm), TDS(mg/liter), Ca+2(mg/liter), Cl-(mg/liter), So4-2(mg/liter),
and PH. For irrigation purpose Standards Iraq were used and inverse distance
waited(IDW) interpolation has been used to make of six parameters spatial
distribution map above. Raster calculator of Arc map GIS 10.2 software presented
water quality index for surface water samples ranged between 53.5092 – 87.5235.

Key word: Water quality index , GIS, physicochemical parameters
