Seasonal and Multi-Year Variation in Manganese Concentrations

Sampling Dates and Range Explanation

The U.S. Geological Survey collected groundwater samples from Marquette County's aquifer 100SDGV between August 3, 2011, and August 19, 2024. These 14 results from 7 wells showed manganese concentrations ranging from 0.14 to 32.5 micrograms per liter (ug/L) with a median of 0.56 ug/L. Detection occurred in half the samples, while the others fell below the reporting limit. The wells sampled varied in depth from 23 to 199 feet.

Implications of Variation

This data reflects natural fluctuations in manganese levels over a multi-year period, illustrating that concentrations may shift within the aquifer over time and depth but consistently remain below federal threshold levels.

Entry of Manganese into Groundwater in Marquette County

Geological and Environmental Sources

Manganese occurs naturally in soil and rock and can dissolve into groundwater through weathering and mineral interactions typical to the aquifer 100SDGV region. These processes affect manganese availability in the water supply reaching household taps.

Distribution Through Groundwater Systems

As groundwater moves through aquifer formations, manganese concentrations vary depending on rock composition, depth, and redox conditions. This leads to the range of values observed in the sampled wells.

Interpreting Detected Manganese Levels Against Federal Standards

Federal Threshold Context

None of the manganese results from the Marquette County aquifer samples exceeded any federal manganese threshold. This means government data do not indicate safety concerns based on these samples.

What Detection Does Not Imply

Detection of manganese does not itself represent a violation or unsafe condition. Manganese is regulated primarily for aesthetic secondary standards related to taste and staining, not health-based limits. Individual household water may differ from these regional results and should be tested to confirm specific conditions.

Distinguishing Manganese Issues from Similar Water Constituents

Difference from Iron and Other Elements

Manganese is often confused with iron due to similar staining effects, but they are chemically distinct and may require different treatment approaches.

Separation from Health-Based Contaminants

Unlike contaminants regulated for health risks, manganese is primarily a concern for water appearance and taste, which influences treatment priorities.

How the Pentair Black Manganese Stains Filter Addresses Household Manganese

Removal and Neutralization Mechanism

The Pentair Black Manganese Stains Filter is designed to reduce manganese concentrations effectively. It works by filtering out manganese particles and preventing staining and discoloration that can arise when existing equipment cannot keep up.

Suitability for Houses with Existing Treatment Equipment

This system ships ready to configure, making it a direct purchase solution well-suited for households experiencing strain on their current manganese removal setup.

Summary and Source Reference

The manganese data discussed reflects sampling of seven wells within Marquette County’s aquifer 100SDGV from 2011 to 2024. These findings, including detection frequencies and ranges, are available from the U.S. Geological Survey's groundwater monitoring site.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-08-19. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.

On record: U.S. Geological Survey sampling of Manganese in the 100SDGV aquifer (Marquette County): 14 results from 7 wells, median 0.56 ug/L, range 0.14-32.5 ug/L; none above any federal threshold
