Water Softener The method used to test water for iron and manganese depends on the form of the element. Filtration System However, elevated levels of manganese in drinking water can be a major concern. High levels of iron and manganese can result in discoloured water and staining of sanitary ware and clothing. Aside from iron, the mineral that is most often found in excess in water is manganese. Reduced water pressure. The water supplier or well owner is responsible for testing for potential contaminants. For extremely high levels of manganese, you will need to perform chemical oxidation along with filtration. Manganese is present in a wide variety of foods, including whole grains, clams, oysters, mussels, nuts, soybeans and other legumes, rice, leafy vegetables, coffee, tea, and many spices, such as black pepper [ 1, 2, 5, 10, 11 ]. 0000000656 00000 n Similarly, if your drinking water suddenly has a bitter and metallic taste to it, it could be pointing to excessive manganese.
