This week, you face a choice between technical approaches to address manganese in your home's water from Morgan County's aquifer 112TILL.
Seasonal and Multi-Year Variation in Morgan County Manganese Records
Sampling from 2011 through 2025 in Morgan County's 112TILL aquifer shows manganese was consistently detected, with measurements ranging from 160 to 343 micrograms per liter and a median of 247 micrograms per liter. These results, gathered from two wells at depths of about 32 to 33 feet, reflect data across multiple years rather than seasonal spikes. The lack of reported seasonal highs or lows suggests manganese levels fluctuate within a stable range over time in this area.
Public Sampling Records Versus Private Well Testing
The data reflect area-wide manganese presence in government-monitored wells, not your private well's exact condition. While these U.S. Geological Survey samples provide valuable regional insight, only a private water analysis can identify manganese concentration in your household water. Public records help frame expectations but don’t replace direct testing of your water source for precise treatment decisions.
Understanding 'Detected,' 'Median,' and 'Range' in Area Manganese Data
Here, 'detected' means manganese was measured above the laboratory’s reporting limit in every sample collected; it does not indicate a violation or unsafe level. The median value of 247 ug/L represents the middle value of the five samples, while the range from 160 to 343 ug/L captures the lowest and highest measurements. These terms describe distribution in government data rather than individual well conditions.
Sample Size and the Implications for Confidence in the Data
The manganese figures come from five samples in two wells, a modest sample size that provides an initial glimpse into regional manganese levels. This small data set means there's variability in measurements, and it is best viewed as indicative of general conditions in the Morgan County aquifer 112TILL rather than a comprehensive assessment. More extensive sampling would be needed to strengthen statistical certainty.
Aesthetic Secondary Standards Versus Health-Based Manganese Limits
The manganese concentrations found in this area are below any federal health-based thresholds. Aesthetic secondary standards refer to factors like taste, staining, and discoloration of plumbing fixtures. Exceeding these thresholds may cause nuisance effects but does not constitute a safety concern. Understanding this distinction helps households decide if treatment is needed for appearance or health reasons.
Stepwise Testing from Cost-Effective Checks to Laboratory Analysis
- Begin with simple water clarity and staining observations at the tap to detect manganese effects.
- Use a certified laboratory to test manganese levels in your specific well water to quantify the concentration.
- Consider testing alongside other common area concerns to optimize treatment needs.
When choosing between treatment technologies, rely on valid lab testing of your water and how manganese presents in your household plumbing.
In conclusion, this page highlighted the consistent manganese presence in Morgan County's aquifer sampled over years and how public data differs from private water testing. Knowing the aesthetic versus health-based standards and testing sequence prepares you to select proper treatment technology, such as the Pentair Black Manganese Stains Filter, which ships ready to configure for household use.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-09-02. 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 112TILL aquifer (Morgan County): 5 results from 2 wells, median 247.0 ug/L, range 160.0-343.0 ug/L; none above any federal threshold
