English Abstract

Kawergosk oil refinery is one of the biggest refineries in Kurdistan Region-Iraq.

The refinery lies on Khabat District and the produced wastewater disposed to Greater-Zab River (GZR).

The effect of Kawergosk refinery wastewater (KRWW) on the surrounded water sources was studied by examining the characteristics of KRWW, GZR and the groundwater.

The impact of the KRWW on the surface and groundwater sources were examined via measuring parameters of pH, oxidation-reduction potential (ORP), phenol, oil and grease, fluoride, salinity, dissolved oxygen (DO), five day biochemical oxygen demand (BOD5), chemical oxygen demand (COD), BOD5/COD, color, ammonia-nitrogen (NH3-N), nitrite, nitrate, zinc, potassium, turbidity, chloride, electrical conductivity (EC), total dissolved salts (TD Salts)… etc.

To assess effect of KRWW on GZR, two locations of GZR were selected one of them was at the disposing point (i.e.

mixing point between the GZR and KRWW) and the other was before disposal of KRWW to the river.

The results of pH, ORP, oil and grease, TDS, Salinity, NH3-N, EC, nitrite, nitrate, SS, turbidity, chloride, total acidity, total alkalinity, and total hardness showed that the GZR was polluted at the mixing point.

For evaluating the effect of KRWW on the groundwater, two groundwater sites were chosen, one of them close to the refinery near Small Agulan village, and the second one was far from the refinery near Al-Jadida village.

Results illustrated that commonly KRWW had not effect on the groundwater.
