Good evening, Blair, and thank you for your inquiry.

Yes, the SenSafe Heavy Metals Check product should detect dissolved Manganese since it typically has a +2 valence state for its electrons BUT do keep in mind that other dissolved metals, if present in your samples, will also yield positive results and the test kit will not differentiate between (or identify) the metals it detects.

If you require a more manganese-specific test kit, then you may want to consider the SenSafe Manganese Check product which includes interference masking agents on each strip to reduce false positive readings given by metals other than Manganese.

Normally if a homeowner finds that he or she has a higher than desirable level of ANY metals in his or her water, regardless of the metals’ identities, that person typically seeks out additional, more qualitative (i.e. laboratory) testing so that a decision regarding what filtering solution will work best for their unique water quality situation can get made.

Laboratory testing for manganese

In the event that you do decide to seek out laboratory testing, we suggest first contacting your local health department to get a list of qualified water testing labs in your area. If that does not work then we suggest considering one of the WaterCheck Test Kits manufactured by National Testing Laboratories.

WINSTON-SALEM, N.C. – In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level.

The study, titled, “Environmental Manganese and Cancer Mortality Rates by County in North Carolina: An Ecological Study,” was published online last month by Biological Trace Element Research. Lead researcher John Spangler, M.D., professor of family and community medicine at Wake Forest Baptist, found that groundwater manganese appears to be positively associated with total cancer, colon cancer and lung cancer death rates, while airborne manganese concentrations appear to be inversely associated with total cancer, breast cancer and lung cancer death rates.

. . .

To determine whether environmental manganese is related to cancer at the county level in North Carolina, Spangler conducted an ecological study using data from the North Carolina State Center for Health Statistics, North Carolina Geological Survey, U.S. Geological Survey, and U.S. Census.

He found that airborne manganese was associated at the county level with an 14 percent decrease in total cancer deaths, a 43 percent decrease in breast cancer deaths and a 22 percent decrease in lung cancer deaths. Additionally, Spangler found there was up to a 28 percent increase in county-level colon cancer deaths and a 26 percent increase in lung cancer deaths at the county level related to elevation of manganese in groundwater as opposed to air.

Testing for Manganese in Groundwater:

For the longest time testing for manganese in groundwater required the use of multiple messy liquids (see HMT Manganese Test Kit) and the results often had false positives as a result of interferences from other metals.

Recently, though, a water testing breakthrough called SenSafe Manganese Check eliminated the need for ALL liquids except the water getting tested. Additionally, users can complete testing for manganese in water within a matter of minutes.

The new and improved SenSafe™ Manganese Check eliminates interferences from several ions like copper, iron, cobalt, lead, nickel, etc. Designed to be a rapid, accurate alternative to wet chemical tests, SenSafe™ Manganese Check offers the user an easy dip-and-read test strip alternative for determining manganese concentrations in water. Detecting levels of <0.02, 0.05, 0.1, 0.2, 0.5, 1.0, and 2.0 ppm (mg/L), SenSafe™ Manganese Check (US Patent #6541269) is ideal for on-site testing when accurate results are immediately needed.
