Studying samples of groundwater in the Wilayat of Mahout, the results indicated an increase in salts to 6,000 and conductivity to 17,000. Studying samples of desalinated water from desalination plants in Mahout, we noticed a decrease in salts in them and an increase in some heavy metals in the water, such as boron and iron, perhaps due to rusting of the metals and pipes that transport the water. Which made us search and study marine peels, since we are in a marine area, so we extracted the chitin protein from them, and then sought help from the Nizwa Research Center to convert it into the chitosan polymer so that we could use it in our studies and find out its effect on water. We found that when adding the sample to groundwater, the salts decreased from 6000 to 2500, the conductivity from 17000 to 9000, and the pH from 9 to 7.1, we then sought to spread awareness about not irrigating crops or drinking it because it contains heavy metals and high salts.
