The thesis presented by researcher Sajjad Faisal Mari'i aimed to study the physicochemical properties of the Ashar River water in multiple stations and reduce the concentrations of heavy metals from the water by using extracts of the Chamomile and Rosemary plants to get rid of these metals.

The thesis included the use of two types of local plants and testing their efficiency in removing heavy metals from the water of the Ashar River.
