  • 1. Part of the Water Wisdom Series for Home Inspectors by: Scott J. Bradley Aquacheck Laboratory, Inc. www.Aquacheck-VT.com 1-800-263-9596
  • 2. Manganese: Symbol - Mn <ul><li>Sources: Manganese can be found in drinking water as a naturally occurring element (metal) and is often times, but not always found where iron is located. </li></ul><ul><li>The USEPA (Environmental Protection Agency) has adopted a Secondary Maximum Contaminant Level (SMCL) for Manganese in drinking water at, 0.05 mg/l (zero point zero five parts per million). </li></ul><ul><li>A secondary contaminant causes aesthetic problems with the water, like odors, or in the case of Manganese, staining. </li></ul><ul><li>manganese ore : India Trade India Trade Company </li></ul>
  • 3. Manganese in Drinking Water <ul><li>Manganese is an essential element for many living things. Certain aquatic plants, like duckweed, can bio- accumulate Manganese to many times it’s original concentration. </li></ul><ul><li>Mn gives the gemstone, Amethyst, </li></ul><ul><li>it’s beautiful purple color. </li></ul><ul><li>If it comes in contact with </li></ul><ul><li>oxygen, it then turns black. </li></ul><ul><li>That’s when it can become </li></ul><ul><li>a problem! </li></ul>
  • 4. Home Inspectors & Manganese Problems <ul><li>Now you know that Manganese can cause black staining – usually in porcelain fixtures like the back of toilet bowls and tanks. </li></ul><ul><li>It may also build up and cause obstruction of water in a distribution pipe, called biofouling. </li></ul><ul><li>If you are a Home Inspector and sampling for Coliform Bacteria in a home with non chlorinated water, too much manganese can cause a positive interference in the chlorine (DPD) test. </li></ul>
  • 5. Home Inspector to Client: <ul><li>Don’t forget to tell someone if their manganese is high, </li></ul><ul><li>SMCL = 0.05 mg/L), that adding chlorine based bleach to the laundry can precipitate the Mn out of solution and cause significant staining. </li></ul><ul><li>There are filters available to take out manganese. Also, an ion exchange (water softener) can </li></ul><ul><li>be used as well as an R.O., or </li></ul><ul><li>reverse osmosis machine. </li></ul><ul><li>I go to the NSF to find out about </li></ul><ul><li>filters and filtration products. </li></ul>
