Drinking Water Advisory - Important information about manganese in your drinking water
Manganese is a nutrient that is part of a healthy diet. Drinking water may naturally contain manganese and, when concentrations are greater than 50 micrograms per Liter (µg/L), the water may be discolored and taste bad. Over a lifetime, the United States Environmental Protection Agency (EPA) recommends that people drink water with manganese levels less than 300 µg/L and over the short term, EPA recommends that people limit their consumption of water with levels over 1,000 µg/L, primarily due to concerns about possible neurological effects. Children up to 1 year of age should not be given water with manganese over 300 µg/L nor should formula for infants be made with that water for longer than 10 days.
Both of our water sources have exceeded the 300 µg/L threshold within the last year. The most recent test results show our source located on Perkins Row contains 394 µg/L of manganese; levels have varied between 150 µg/L and 370 µg/L in 2013 with an average of 313 µg/L. The most recent test result for our source located on North Street contains 94 µg/L; levels have varied between 70 µg/L and 1,270 µg/L during 2013 with an average of 391 µg/L.
