18-10-2019· Manganese often results in a dense black stain or solid. For these reasons, it is recommended that drinking water have no more than 0.3 mg/L (or 0.3 parts per million) of iron and less than 0.05 mg/L of manganese. The U.S. Environmental Protection Agency has also set a Health Advisory for manganese of 0.3 mg/L.
Important sources of manganese include soils, sediments, and metamorphic and sedimentary rocks (Reimer, 1999). Crustal rock is a major source of manganese found in the atmosphere. Ocean spray, forest fires, vegetation, and volcanic activity are other major natural sources of manganese in the atmosphere (Schroeder et al., 1987; Stokes et al., 1988).

If the pH is too high, use an acidifying agent, such as sulfur, to lower the pH but just ensure that the pH doesn't drop so low as to result in other nutrient imbalances. If you have doubts about the amount of nitrogen your plants are getting, adding nitrogen can also boost the uptake of manganese.
The principal source of exposure to manganese is from food, but in situations where manganese levels in drinking water are elevated, the contribution from drinking water can increase the overall intake of manganese. Manganese is found naturally in groundwater and surface waters in Iowa.

Divalent manganese (Mn 2+) predominates in most waters (pH 4–7), but may become oxidized at pH greater than 8 or 9. The principal anion associated with Mn 2+ in water is usually carbonate (CO 3 2− ), and the concentration of manganese is limited by the relatively low solubility (65 mg l −1 ) of MnCO 2 .
