Manganese in Water: Health Risks and Symptoms

Question
Hi,
I'm not sure if this question fits in your line of expertise or not.  My husband and sons work at a place where the water has lots of manganese in it.  The water lying around the faucets turns blackish and gunky.  It worries me that they will get too much.  Is this possible?
What are the symptoms of too much?  Thank you for your time.
Kathleen

Answer
Kathleen,

Manganese is a necessary element for good health, as it is a co-factor in at least one enzymatic reaction w/in our bodies.  Like many things, too much can be a bad thing.  Some elements the body can tolerate very high levels or purposeful exogenous or even accidental intake, while others may be toxic.  Iron for example is good and necessary but too much can be harmful.  Magnesium (Mg) is one that is very well tolerated at even superphysiologic doses, but in the end it too can have toxic effects.  As far as Manganese (Mn)goes, and that may not be the only "thing" in the water that is turning it dark, one should TEST the water first for mineral and toxin content if there is a work place concern.  Secondly, a mineral survey (blood work) can be performed to determine if there is a dangerously high level of Mn or any other metal for that matter in their system.  Any doctors office can order these tests.  Alternatively hair analysis can be performed for chronic exposures and levels.
