Overview of Iron in Madison County Aquifer 337FRPN

Water used in Madison County households often comes from deep wells drawing from aquifer 337FRPN, generally between 30 and 79 feet underground. Understanding iron levels in this water source is key to addressing issues like rust stains or metallic taste in water.

Reading Certified Laboratory Iron Test Reports

Iron Concentrations are Reported in Micrograms per Liter (ug/L)

Iron test results from certified labs typically state the concentration of iron in micrograms per liter, showing the amount detected but not indicating safety by itself.

Detection Does Not Equal Safety Concern

Detected iron means a measurement was made; it does not imply a health risk or water quality violation.

Sampling Scope and Data Interpretation

Local Sampling Includes 27 Tests from 7 Wells

Between 2011 and 2024, 27 samples were collected from seven wells in Madison County’s aquifer 337FRPN, providing a representative but limited picture of regional iron levels.

Median and Range Provide Context

The median iron level found is 3.8 ug/L, with the range spanning from no detection to 22.7 ug/L. Individual well conditions may vary.

Small Sample Size Limits Broad Assumptions

Because a relatively small number of wells were tested, these figures serve as regional estimates rather than guarantees of any specific well’s iron content.

Understanding Aesthetic Secondary Standards Versus Health Limits

Secondary Standards Address Taste and Staining

Iron measurements exceeding 0.3 milligrams per liter fall above the secondary standard, which relates to appearance, taste, and rust staining rather than health.

These Standards Do Not Indicate Unsafe Water

An iron reading above this threshold is not a violation or health concern but a signal that rust or discoloration may be noticeable.

Recommended Steps to Identify Iron-Related Water Issues

Start with Visual and Practical Observations

Check for rust-colored staining on fixtures or laundry, and note any metallic taste in water.

Conduct a Certified Lab Test of Your Own Well Water

Only a laboratory analysis of your household water will confirm specific iron levels, as regional data can't reflect individual variations.

Verify Depth and Construction of Your Well

Well depth impacts iron presence; knowing these details helps interpret potential issues.

What Changes When Using Pentair Orange Iron & Rust Stains Filter

Reduction of Visible Rust and Iron Stains at Water Outlets

This system targets iron compounds associated with rust, helping maintain cleaner fixtures and brighter laundry.

Improved Water Clarity and Taste

By addressing iron particles, the filter can help reduce metallic tastes often linked to iron content.

Difference Between Public System Records and Private Well Testing

Public Data Reflect Regional Sampling, Not Individual Wells

Public water system records in Madison County show iron levels within monitored ranges but do not replace private well testing for personal water quality assurance.

Private Well Testing Provides Specifics for Treatment Decisions

Individual test results enable targeted selection of water treatment suited to actual iron levels and water conditions.

What You Should Not Conclude From Regional Iron Sampling

Area sampling results should not be taken as confirmation of your own water’s iron concentration. They do not imply health risk or regulatory noncompliance, nor do they precisely predict water taste or staining in your household. Testing your own water is the only way to determine the appropriate class of treatment needed for iron and rust issues.

Where this information comes from

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
