Government groundwater sampling by the U.S. Geological Survey in Lee County's aquifer 230SDMR found iron detected in 33 out of 53 well samples, with a median concentration of 11.3 micrograms per liter and a range from 3.3 to 330.0 micrograms per liter. None of these results exceeded any federal health-based thresholds.

How Treated Water Will Differ at Your Tap

Reduction in visible rust staining

Using the Pentair Orange Iron & Rust Stains Filter can reduce rust-colored stains on fixtures and laundry caused by iron in water.

Clearer water appearance

The filter helps diminish the reddish or brown coloration often caused by iron, improving water clarity.

Lowered metallic taste and odor

Treated water typically exhibits fewer metallic tastes or odors associated with iron.

Understanding 'Detected', 'Median', and 'Range' in the Sampling Record

'Detected' means measurable iron was found in 33 wells

This indicates that iron was present at some level, but not necessarily problematic or in all wells.

'Median' of 11.3 micrograms per liter represents the midpoint concentration

Half of the detected iron measurements were above this value, half below.

'Range' from 3.3 to 330 micrograms per liter shows variability

Concentrations vary widely across the sampled wells, reflecting natural or geological differences.

Household Symptoms Indicative or Not Indicative of Iron and Rust

Indicative symptoms:

• Reddish-brown staining on sinks, tubs, or toilets
• Rusty residue on clothes after washing
• Metallic taste or slight discoloration in water

Not indicative symptoms:

• Cloudy or milky water (often related to air bubbles)
• Foul or sulfurous odors (caused by other compounds)
• Persistent biological growth or slime (from bacteria)

Seasonal and Multi-Year Variations in Iron Levels

Sampling dates from April to August 2012

The data covers late spring through summer months, showing conditions during that period.

Variability likely influenced by groundwater conditions

Iron levels can fluctuate with water table changes and aquifer chemistry over seasons or years, but this dataset provides a snapshot in time.

No data on other seasons or multi-year trends available here

Additional monitoring would be needed to track longer-term changes.

Maintenance Rhythm with the Pentair Orange Iron & Rust Stains Filter

Periodic replacement or regeneration of filter media is needed

Neutral maintenance activities keep the filter effective in reducing iron stains.

Routine checks ensure consistent performance

Monitoring water quality at the tap helps identify when filter servicing is due.

No specialized tools or service agreements are required to manage the system

The system ships ready to configure for household use.

Additional Questions for Commercial or Industrial Operators

Scale of water usage and flow rates

Larger volumes may require differently sized equipment beyond the household system.

Compliance with local regulations for discharge or reuse

Commercial operations may have legal obligations related to iron levels treated or discharged.

Monitoring iron forms and other constituents relevant to processes

Industrial users might need detailed analysis beyond total iron concentrations.

The key test to clarify your household’s iron situation is a certified water analysis of your own well or tap water. A laboratory iron concentration result will determine the level of treatment needed and confirm whether the Pentair Orange Iron & Rust Stains Filter fits your treatment requirements.
