What a Certified Laboratory Test Reports and How to Read It
Test shows manganese concentration in micrograms per liter (ug/L)
A certified water analysis will state the manganese level found in your water sample, reported in micrograms per liter (ug/L). The result helps determine if manganese is present and at what amount, but by itself does not identify safety or violation status.
Detected versus non-detected results
Detection means an instrument measured manganese in your water, not that the water is unsafe. Some tests may report manganese below their reporting limit, indicating very low or no measurable manganese.
Compare your report to area data with care
Johnson County area sampling showed manganese detected mostly between about 31 and 259 ug/L, but your own water test is needed to know your home's exact level.
Maintenance Rhythm of the Pentair Black Manganese Stains Filter
Regular media refresh cycles
The Pentair Black Manganese Stains Filter is designed to remove manganese effectively from household water. It requires periodic media regeneration or replacement that typically aligns with water usage patterns and manganese concentration.
Monitor performance indicators
Visual and taste changes in treated water, plus scheduled system checks, guide maintenance timing. The filter ships ready to configure with straightforward operational steps.
A Worked Example: Reading the Regional Manganese Median and Range
Median manganese concentration is 237.5 ug/L in Johnson County aquifer samples
This median indicates that half the sampled results were above and half below this manganese level, representing typical conditions found in sampled wells.
Range from 30.8 to 259.0 ug/L reflects variability
Different wells showed manganese levels spanning this range, illustrating natural variation across locations and depths of 17 to 177 feet.
Sample Size and Its Meaning
Five manganese results from four separate wells
The area data is based on a small number of samples, so it offers a limited snapshot rather than a complete picture of all wells in Johnson County.
Limited sampling scope advises caution
Without more extensive or recent data, residents should rely on individual water testing to understand their own water quality precisely.
Additional Questions for Commercial or Industrial Users
Higher volume water demands and process sensitivities
Commercial or industrial operators consider manganese impact on equipment, process water quality standards, and operational costs beyond typical residential concerns.
Regulatory and reporting differences
Businesses often face distinct monitoring frequency and compliance documentation not required for household water.
Summary: Regional manganese data for Johnson County’s aquifer provides a general idea of what might be found in wells but cannot substitute for your own water test. The Pentair Black Manganese Stains Filter offers a documented approach to reduce manganese effects, with straightforward maintenance suited to household water use.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-08-28. 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 111ALVM aquifer (Johnson County): 5 results from 4 wells, median 237.5 ug/L, range 30.8-259.0 ug/L; none above any federal threshold
