If you see 'detected', 'median', and 'range' in Shelby County iron bacteria data, what do they mean?

The U.S. Geological Survey sampled groundwater in Shelby County's aquifer 100ALVM in 2017, measuring iron levels across five wells at depths from 55 to 166 feet. Iron was detected in all ten test results, with no results below the reporting limit. The median iron concentration was 16,200 micrograms per liter (ug/L), with the range spanning from 2,850 to 24,500 ug/L.

Detected means the sampling instruments measured iron at those levels; it does not mean a violation of any federal limit, since no results exceeded regulatory thresholds. The median shows the middle value of the sample set, giving a general indication of typical iron levels. The range indicates the variation from lowest to highest detected levels in the tested wells. These figures apply to the sampled area and wells, not directly to your household water. Only testing your own water can establish precise levels at your location.

If iron bacteria remain untreated in your household water for years, what occurs?

Iron bacteria can create reddish-brown slime or staining in plumbing fixtures, water-using appliances, and laundry. Over time, slime buildup may clog pipes or reduce water flow. While iron bacteria are not classified as a safety hazard by federal standards, their presence can affect water aesthetics and household maintenance requirements. Without treatment, stains and slime may become persistent and more difficult to remove.

If sampling occurred at various well or source depths, how does that affect your expectations?

Sampling in Shelby County occurred in wells between 55 and 166 feet deep, representing typical groundwater accessed in the aquifer. Generally, deeper wells or different source types may show varying iron concentrations. Shallow wells or surface water sources might differ significantly from these measurements. Therefore, the reported iron levels help set a baseline for the area but are not a definitive predictor of your well's iron content.

How might a homeowner interpret the median and range of this sampling record practically?

The median iron concentration of 16,200 ug/L suggests that many wells in the area have measurable iron, with some as low as 2,850 ug/L and others rising to 24,500 ug/L. This tells a homeowner that iron presence is common and can vary widely depending on the specific well. If your water has issues consistent with iron bacteria, such as staining or slime, it is reasonable to test your own water for iron and iron bacteria to confirm whether treatment may be needed.

What additional questions would a commercial or industrial water user need to consider beyond a residential homeowner?

Commercial and industrial operators often require detailed water quality data related to equipment compatibility, process water standards, and regulatory compliance. They might also assess the impact of iron bacteria on large-scale systems, potential effects on production processes, and the cost-benefit of various treatment approaches. Residential concerns focus more on water appearance and fixture maintenance, while commercial users look into operational impacts and regulatory parameters.

How do public water system records differ from private well testing in the information they provide?

Public or municipal system records, like the U.S. Geological Survey data for Shelby County, provide information on area-wide water quality trends and aquifer characteristics. These records do not replace testing your private well since individual well conditions can vary widely within the same area. Private well testing provides precise, site-specific data needed to make informed decisions about treatment. Municipal records help homeowners understand general expectations but are not conclusive for individual water conditions.

In response to iron bacteria issues indicated by local sampling figures, the Fleck Iron Bacteria & Slime Filter ships ready to configure and offers a documented solution to reduce iron bacteria and slime in household water. Testing your own water to confirm demand levels helps in selecting the appropriate treatment capacity.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-09-28. 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 Iron in the 100ALVM aquifer (Shelby County): 10 results from 5 wells, median 16200.0 ug/L, range 2850.0-24500.0 ug/L; none above any federal threshold
