This information is also available as a PDF document: Manganese in Drinking Water (PDF). At concentrations as low as 0.02 mg/l, manganese can form coatings on water pipes that may later slough off as a black precipitate (Bean, 1974). Removing manganese with a filter is often easier if iron is present. Manganese is a naturally occurring metal that is found in many types of rocks. While a small amount of manganese is essential for human health, new Health Canada research has shown drinking water with too much manganese can be a risk to health.

In general, manganese is more prevalent and found at higher concentrations in groundwater than surface water. Manganese occurs naturally in PEI rocks and soils. Naturally-occurring manganese in soil and rocks is rarely an issue. Instead, they both have secondary or recommended drinking water standards because they cause aesthetic problems that make the water undesirable to use in the home and a bitter metallic taste that can make the water unpleasant to drink for both humans and farm animals.Iron can also cause an orange or brown stain in sinks and in the laundry. 0000002618 00000 n EPA has established a Health Advisory Level for Manganese in drinking water. Product Certification provides an additional level of assurance to consumers who want protection from manganese.
