Government sampling by the U.S. Geological Survey in Waushara County's 100SDGV aquifer found manganese concentrations ranging from 0.67 to 199.0 micrograms per liter (ug/L) in 11 samples taken from seven wells between July 2013 and August 2024. The median concentration was 2.47 ug/L. None of these samples exceeded any federal manganese thresholds.

If you want to reduce manganese stains and discoloration in your household water

The documented Fleck Black Manganese Stains Filter is designed to target manganese in water by filtering out particles that cause staining and discoloration. This system uses a specialized filtration media that captures manganese and prevents it from affecting faucets, fixtures, and laundry. It ships ready to configure for your home water setup.

If you suspect your water issues may be manganese but also consider similar problems

Manganese is often confused with iron and other minerals that cause similar staining or discoloration. However, manganese typically leaves black or dark brown stains, while iron tends to create reddish or orange marks. Unlike some other minerals, manganese in these regional samples does not pose a health-based risk according to federal standards.

If you are curious about how manganese levels in your region change over time

The USGS sampling dates from 2013 to 2024 show manganese ranged from below the reporting limit in some samples to a high of 199.0 ug/L, reflecting natural variability over more than a decade. This variation suggests manganese concentrations can fluctuate seasonally or over multiple years depending on aquifer conditions.

If you want to understand how manganese enters groundwater in Waushara County

Manganese naturally occurs in soil and rocks and can dissolve into groundwater through geochemical processes. In Waushara County’s aquifer system, depth of sampled wells ranged from 39 to 147 feet. The manganese found in groundwater reflects local geological formations rather than contamination from human activity.

If you notice water stains or discoloration but wonder whether manganese is the cause

• Symptoms that suggest manganese presence: black or dark brown staining on sinks, tubs, and laundry, water that looks cloudy or has black particles.
• Symptoms less likely linked to manganese: unusual tastes or odors not typical of manganese; red or orange staining (more indicative of iron).

If you want to compare manganese levels here with neighboring counties

While Waushara County’s manganese data shows a moderate range, comparing it with adjacent areas should be done carefully. Different counties have unique geological formations affecting manganese occurrence. Do not assume your household water matches regional data without testing your own supply.

It is important to understand that regional manganese data reflects conditions in sampled wells and aquifers but does not specify your household’s water quality. A water test for manganese and other constituents is necessary to determine if treatment is appropriate for your home. The Fleck Black Manganese Stains Filter offers a proven approach to manage manganese-related staining if your water testing confirms the need.
