Interpreting a Certified Lab Report on Iron Bacteria
What the report lists
A laboratory test report for iron bacteria typically includes iron concentration measured in micrograms per liter (ug/L), along with indications of bacterial presence. The report distinguishes whether iron is detected above the laboratory’s reporting limit or below it. These numeric results provide a starting point for understanding water characteristics but do not by themselves define water safety or treatment needs.
Comparing El Paso County to Neighboring Areas
Data context matters
El Paso County’s aquifer 111ALVM iron measurements come from U.S. Geological Survey data spanning many wells and years. Comparing these results to nearby counties should be done cautiously because geological and hydrological factors vary significantly. Differences in sampling depth or timing may affect iron levels, so regional comparisons inform trends rather than household-specific conditions.
Consequences of Untreated Iron Bacteria
Gradual impact on household systems
Iron bacteria can build up as slime and deposits inside plumbing and appliances, leading to staining, reduced water flow, and potential need for maintenance. Over many years, untreated iron bacteria growth may impair water fixtures’ function and appearance but does not directly imply a health risk. Early recognition and management help maintain home water quality and system longevity.
Understanding Terms in the Sampling Record
Detected, median, and range explained
- Detected means iron was measurable above the lab’s reporting limit but is not a violation or unsafe level.
- Median iron concentration of 12.45 ug/L indicates the middle value among detected results, showing a typical level found in this area.
- Range spans from 4.1 up to 1680.0 ug/L, representing the lowest and highest iron concentrations measured across samples, reflecting natural variability.
Sample Size and Data Reliability
What the sampling effort shows
The iron data for El Paso County is based on 160 observations from 50 wells sampled between 2013 and late 2025. Well depths ranged between 16 and 215 feet. This substantial dataset provides a reliable picture of regional iron presence but cannot replace an in-home water test, which accounts for individual well characteristics.
How the C-Series Iron Bacteria & Slime Filter Works
Technology overview
The C-Series System is designed to address iron bacteria and slime issues by filtering and neutralizing iron-related compounds that contribute to bacterial growth and deposits. It manages both the biological and mineral components that lead to staining and clogging, helping maintain clearer water and reduce buildup in plumbing over time. The system ships ready to configure for household needs.
Recommended Next Step: Testing Your Water
Confirming your household’s iron bacteria level
To determine the specific iron bacteria condition in your water, arrange for a certified laboratory test focused on iron concentration and bacterial presence. Results below typical regional ranges suggest mild conditions, while higher values may indicate a greater need for treatment. This targeted test provides the data needed to decide if the C-Series filter or similar solutions are appropriate.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-12-18. 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 Iron in the 111ALVM aquifer (El Paso County): 160 results from 50 wells, median 12.45 ug/L, range 4.1-1680.0 ug/L; none above any federal threshold
