Abstract:

The present investigation deals with the physico-chemical analysis of Zea River which passes through the Deralok City, an agricultural town of Duhok province. The objective of the study was to provide baseline information on its physical and chemical characteristics as well as evaluate its water quality. Water samples were collected during dry and wet seasons from seven stations and analyzed for various physico-chemical parameters. Assessment of temperature, pH, Dissolved Oxygen, total alkalinity, turbidity, chloride, hardness, dissolved oxygen, calcium, Sulphate, total dissolved solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Electrical Conductivity were carried out monthly during November, 2014 to June, 2015. Results showed significant alterations in the physicochemical parameters. The analyzed data of water body was interpreted in relation to pollution status and biodiversity indices for assessment of aquatic fauna. Atmospheric temperature ranged from 2.12 to 45.25 (ºC). Water temperature ranged from 10.71 to 16.01 (ºC). pH ranged from 7.27 to 8.73, dissolved oxygen from 7.53 to 9.01 (mg/l), electrical conductivity from 316 to 398 (μS/cm), total dissolved solids from 202 to 255 (mg/l), turbidity from 86 to 92 (NTU), total hardness from 206 to 216 (mg/l), total alkalinity from 58 to 76 (mg/l) and total acidity (53–83 mg l-1),  BOD (2.7–3.7 mg l-1), COD (1.7–2.1 mg l-1). Results show that there is no serious problem regarding the parameters checked in this study. So, the water can be used as drinking water for Deralok city and another city without any serious problem. The results suggest that refuse disposal, fertilizer use, and natural phenomena e.g. soil erosion; flooding, etc. may have contributed in various ways to the impairment of the water quality of the studied sites. Although the results do not indicate adverse pollution status of any of the sites, they provided the need for further investigations and monitoring. The water from the river which is called Zea, travels from turkey to Kurdistan in a small city called Deralok it also goes through the middle of the city. This separates the city into 2 pieces. From Deralok the river goes through many villages and woods then it joins with another river called the blue (shin) river. Also the Zae River is 75km far away from the province of Duhok.
