Iron and Manganese Removal Treatment From Drinking &

Options for Iron and Manganese from Groundwater. There are several methods that can be used for iron and manganese control and removal for groundwater. The United States Department of Agriculture suggests having the water tested before deciding the best method of removal, because the success of different treatments depends on factors such as the hardness of the water, pH, and the
