Assistance Type: OTHER WATER QUALITY - Follow up on manganese sample results
Reasons: Other
Details: On July 22, Pinewood Mobile Manor reported a water sample test result for manganese to the Drinking Water Program. This letter is to inform on the results and what it could mean for monitoring and maintaining your community drinking water system. Also attached is a fact sheet for more information on the naturally occurring element, manganese, and its drinking water standards.

On June 16th the Manganese results were 0.163 mg/L

This result is lower than the drinking water health advisory level for bottle-fed infants which is 0.3 mg/L. This result is also lower than the health advisory level for all persons which is 1.0 mg/L. Manganese levels tested below these standards are not anticipated to significantly affect health over a specific duration for a person (for example, one day, ten days, or a lifetime).

This result is above the ‘secondary standard” for manganese, which affects the aesthetics of the water. In other words, how the water looks and its potential effect on staining plumbing fixtures, laundry, and taste. The secondary standard level for manganese is 0.05 mg/L.

Continue monitoring Manganese on a semi-regular basis to ensure that the levels are still under the health advisory level for infants 0.3 mg/L. I would recommend once every year to add to your internal informal monitoring schedule. Manganese is currently not regulated, and will not be added to your formal chemical monitoring schedule.

There are several treatment options that may be discussed and applied for with a plan review with the Drinking Water Program. Please contact before making changes or installing to any water treatment at the well, as the treatment installed will need to be verified that its NSF approved and that it will actually work to remove manganese.
