What 'Detected,' 'Median,' and 'Range' Mean in Madison County's Water Sampling
Government data from the U.S. Geological Survey sampled groundwater from seven wells in Madison County's aquifer 337FRPN over more than a decade. The term 'detected' means the measuring instruments found some iron presence in 22 of the 27 samples, not that it is necessarily high or harmful. The median value of 3.8 micrograms per liter (µg/L) indicates that half the samples measured above this figure and half below. The range from 0.0 to 22.7 µg/L shows variability but reflects regional levels, not what your individual household water contains.
Interpreting the Range in Light of Federal Aesthetic Standards
Four measurements in the Madison County wells tested above the secondary standard for iron, which is 0.3 milligrams per liter (mg/L), a threshold concerned only with potential taste and staining effects. This secondary standard is not a health-based limit and exceeding it is not a violation or unsafe. Many samples remain below this level. Therefore, metallic taste may occur for some residents nearby but does not automatically indicate a health risk or legal problem.
How Well and Sample Depth Influence What You Might Experience
The sampled wells ranged from 30 to 79 feet deep, typical for the local groundwater. Depth influences water characteristics because shallow and deep wells may draw from different layers. Your household water might differ depending on its source depth, so regional data provide context but do not guarantee your water’s iron content or taste.
Comparing Madison County's Sampling Record with Neighboring Counties
Sampling from Madison County’s aquifer gives a snapshot of regional water quality, but nearby counties may have different geological factors affecting water taste. Comparing data across counties can offer perspective but shouldn't be used to infer your home’s specific issues without a direct test.
Why Aesthetic Secondary Standards Are Not Health Limits
Secondary standards address issues like taste, odor, and staining and are based on consumer acceptability, not safety. Iron’s secondary standard exists because elevated iron may cause a metallic taste or color changes in water but does not indicate health risk. Understanding this distinction helps focus on managing discomfort rather than alarm.
Confirming the Cause of Metallic Taste in Your Water
To know if your home's water contains iron levels causing metallic taste and whether it’s above aesthetic thresholds, a specific water test targeting iron concentration is needed. This test, conducted on your household water, offers clarity beyond what regional sampling can provide.
For households seeking a solution, the C-Series Metallic-Tasting Water Filter ships ready to configure and is designed to reduce the metallic taste associated with iron and similar constituents. Using this equipment can improve taste based on confirmed water conditions.

Source: USGS groundwater sampling. Sampled 2024-08-21. 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 337FRPN aquifer (Madison County): 27 results from 7 wells, median 3.8 ug/L, range 0.0-22.7 ug/L; 4 above an AESTHETIC secondary standard only (secondary standard 0.3 mg/L (aesthetic)) - not a health finding
