This project aims to measure the amount of boron (105B) in water samples taken from the rivers and streams of the city of Maysan. It passes through the southern Iraqi province of Maysan. ICP/EPA methods were used to analyse water samples collected from 35 different locations. According to the investigation results, the boron concentration in the water ranged from 2.13 parts per million) from the city of Al-Mashrah (S4) to (0.28 parts per million) in the city of Al-Azair. (S27). The results are compared to those reached by previous research. The results can be used to support the relevant authorities in implementing water quality regulations and to give special attention in the event of contamination, enabling them to monitor radiation-free water samples that people need. The study results showed that, apart from a few samples that may indicate potential future contamination threatening both people and the environment, most samples from the study sites exhibited very low concentrations.
