What to Note Before Seeking Treatment Advice

Record the source of your water supply

Identify if your household water comes from a private well or a community system drawing from aquifer 122CBRV in Whitman County.

Document any unusual staining or discoloration

Note if you see dark stains on fixtures or laundry, which can be caused by manganese presence.

Obtain or plan for lab testing of your household water

The only way to know your home’s manganese concentration is through a certified laboratory analysis of your water sample.

Understanding 'Detected', 'Median', and 'Range' in Local Sampling

'Detected' means measurable manganese was found

Of 15 samples from 7 wells in aquifer 122CBRV, manganese was detected in 12, indicating it is commonly present in the area’s groundwater.

'Median' is the middle value among samples

The median manganese concentration was 54.35 micrograms per liter (ug/L), giving a central tendency across sampled wells.

'Range' shows variability in sample results

Concentrations varied from as low as 2.62 ug/L to as high as 118.0 ug/L, reflecting natural differences in groundwater chemistry.

Comparing Whitman County’s Manganese Data with Neighboring Regions

Avoid assuming your well matches area medians

Area samples characterize local aquifer conditions but don’t provide your household’s exact manganese level.

Look for differences in sampling methods or sources

Neighboring counties may show different manganese patterns due to geology, well depths, or water use, but comparisons require contextual understanding.

Use comparison only for general awareness

These data help understand regional trends and potential concerns, not to diagnose specific well water.

Additional Questions Commercial or Industrial Users May Consider

Evaluate volume and consistency of manganese levels

Large or constant water use settings may need ongoing monitoring beyond single sampling events.

Consider regulatory and process impacts

Commercial entities might assess manganese effects on processes or equipment beyond household concerns.

Inspect variation with depth and source type

Knowing exact well depths and water sources can influence treatment planning for commercial users.

Influence of Sample Depth and Well Depth on Manganese Concentrations

Sampled wells ranged from 90 to 907 feet deep

Manganese concentration can differ with depth; deeper wells might tap different water layers with varying manganese.

Deeper wells may show distinct manganese levels compared to shallow ones

This variability means your well’s depth is an important factor when interpreting area manganese data.

Source type (aquifer vs. surface) matters

This data covers groundwater from aquifer 122CBRV; surface water or other sources may differ in manganese presence.

Seasonal and Multi-Year Variations in the Manganese Record

Samples collected over a 10-year span (2014 to 2024)

Long-term data show manganese presence is persistent in the aquifer rather than a short-term anomaly.

Variations within this time are natural and expected

Fluctuations in manganese levels may relate to rainfall, groundwater flow, or other natural factors.

Regular testing helps track changes relevant to your water quality

Periodic sampling provides actionable data for managing household water quality concerns.

Addressing Manganese Issues for Your Household

When manganese presence affects your water quality, the Fleck Black Manganese Stains Filter ships ready to configure and offers a proven treatment approach. This system targets manganese to reduce staining and improve water clarity based on your measured concentration.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-08-07. 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 122CBRV aquifer (Whitman County): 15 results from 7 wells, median 54.35 ug/L, range 2.62-118.0 ug/L; none above any federal threshold
