Interpreting Median and Range Iron Concentrations for a Household
A laboratory report for iron typically states concentrations in micrograms per liter (ug/L). In Providence County's aquifer 112TILL, the U.S. Geological Survey recorded four samples from one well between June 2015 and May 2016. The median iron level was 90 ug/L, with results ranging from 80 to 140 ug/L. These values represent measured iron content in local groundwater samples, not specific household water. None of these measurements exceeded any federal thresholds for iron.
For a homeowner, this means iron in the area is persistently detected but within ranges considered typical. A test of your own well water is essential to establish your exact iron levels since area samples provide context but not specifics.
Additional Considerations for Commercial or Industrial Water Users
While households primarily consider aesthetic effects such as staining or discoloration from iron and rust, commercial or industrial operators evaluate other factors. These include the impact of iron on equipment longevity, process interference, and scale buildup. They may require more frequent sampling and specialized analysis due to operational demands. Residential users generally do not face such extensive testing and focus instead on visible or taste-related symptoms.
Symptoms Household Water Quality Issues May or May Not Indicate
Iron in water can cause reddish-brown staining on fixtures, laundry discoloration, and a metallic taste. These symptoms often prompt households to seek solutions targeting iron and rust. However, not all discoloration signals iron; other minerals or pipe conditions might contribute. Conversely, some iron presence can be unnoticed without visible stains or taste changes. Testing is the only way to confirm iron's role.
Sample Size and Depth: Understanding Data Limitations
The referenced data comes from four samples taken from a single well at a shallow depth of 18 feet. This limited scope means the results provide a snapshot of local groundwater iron but may not capture wider variability. Small samples cannot establish comprehensive area conditions or individual wells’ profiles. Homeowners should consider their water source's specifics when applying these findings.
Comparing Providence County’s Iron Record with Neighbouring Regions
When comparing Providence County’s median iron of 90 ug/L to adjacent counties, differences may appear due to geology or aquifer characteristics. However, caution is needed to avoid overinterpreting such differences. Variations can reflect sampling depth, timing, or number of wells rather than meaningful water quality changes. The key takeaway is that Providence County’s iron levels fall within a moderate range observed in similar regional aquifers.
In summary, the iron concentrations recorded by the U.S. Geological Survey for Providence County aquifer 112TILL originate from four samples in a single shallow well and indicate moderate iron presence without exceeding federal limits. These measurements provide a regional context rather than direct evidence of any individual household water quality.
For households evaluating treatment options, the C-Series Orange Iron & Rust Stains Filter ships ready to configure and is designed specifically to reduce iron and rust staining based on such regional data. Confirming your own water’s iron levels through testing is essential to choosing the correct equipment.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-05-17. 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 112TILL aquifer (Providence County): 4 results from 1 wells, median 90.0 ug/L, range 80.0-140.0 ug/L; none above any federal threshold
