The study aimed to evaluate the physical and chemical properties of industrial wastewater from a pharmaceutical plant in Samarra, Iraq, in order to determine the feasibility of its use for agricultural irrigation. Two samples were collected for each month of July and October 2022. The results of the study showed that the variables pH, Biochemical Oxygen Demand (BOD), Total Hardness, and Ammonia (8.5, 192, 280, and 12.6, respectively) exceeded the Iraqi standards for agricultural irrigation. This suggests that the water is not suitable for irrigation in its current form. On the other hand, the results showed that the Temperature, Calcium hardness, Magnesium hardness, Chloride, Total Dissolved Solids (TDS), Electrical Conductivity (EC), Phosphate, and Nitrate (28, 225, 39.1, 80, 580, 983, 3.1, and 5.11, respectively) were within the Iraqi specifications. As a result, the water was not suitable for agricultural irrigation in its current state due to the four exceeding the maximum limits. Therefore, the treatment plant should develop and improve its treatment processes to meet the necessary standards before discharging the treated wastewater into the river.
