Manganese in Alaska well water
In Alaska, manganese was detected in 95% of 2,282 tested private well samples.
Manganese stains fixtures and laundry above 50 ug/L. EPA's health advisory is 300 ug/L; infants are the most sensitive, and newer research links elevated manganese to neurological effects in children. It is one of the most common private well problems in New England.
