Your decision this week is whether your current system's ability to control iron and rust in household water meets ongoing needs or additional steps are needed.
How should I interpret the median and range of iron detected in Logan County aquifer 327KNWH?
The U.S. Geological Survey recorded iron in six wells sampled in Logan County's aquifer 327KNWH in summer 2017. The median iron concentration was about 235 micrograms per liter, with results ranging widely from approximately 11 to 1440 micrograms per liter. This range shows that iron presence can vary significantly across locations even within the same aquifer. As a homeowner, this suggests your well’s iron level could be closer to the low or high end, but exact concentration requires your own water test.
How can I compare Logan County's iron levels with a neighboring county without overreading the data?
When comparing the iron measurements from Logan County to nearby areas, it's important to note that each aquifer has unique geology and depths affecting iron concentrations. Logan County's sample median and range reflect conditions specific to aquifer 327KNWH. Nearby counties may show different iron levels due to natural variation. Using these area figures only provides context; it does not predict your household well's water quality directly.
What impact do sample depth, well depth, or source type have on expected iron levels?
The sampled wells in Logan County ranged from 10 to 87 feet deep. Iron concentrations can vary with well depth because iron typically dissolves from minerals found at certain depths. Shallow wells may have different iron profiles than deeper ones. The exact source rock, groundwater flow, and oxygen exposure also influence iron presence. Your water system’s performance in controlling iron could depend on these local factors.
Why do aesthetic secondary standards differ from health-based limits for iron, and how does that apply here?
Iron is regulated with aesthetic secondary standards focused on taste, staining, and corrosion effects rather than health risks. The government samples in Logan County showed no iron levels exceeding any federal health-based thresholds. This means iron detections here reflect natural mineral content, which can cause reddish stains and metallic taste but do not indicate a safety violation or health threat in this context.
How do public-system water records differ from private-well testing in what they establish about iron?
Government sampling provides regional data from multiple wells, offering a general picture of iron presence in Logan County’s aquifer. However, this data does not confirm iron levels in your household’s private well. Only direct testing of your water can establish your actual iron concentration and its impact on your water system. Public records serve to inform about area conditions but cannot replace individual water analysis.
What maintenance schedule applies to the Pentair Orange Iron & Rust Stains Filter for managing iron?
The Pentair Orange Iron & Rust Stains Filter ships ready to configure and is designed to reduce iron and rust staining in household water. Maintenance typically involves periodic checking and replacing filter media components to ensure continued effectiveness. Following the manufacturer’s guidelines for maintenance intervals keeps the system functioning to complement your existing equipment, especially when current treatment struggles to keep pace.
From the available Logan County data, do not conclude your water definitively matches these iron levels or that any detection is a safety concern. The varying concentrations highlight the importance of testing your own water and considering treatment technologies like the Pentair Orange Iron & Rust Stains Filter to address persistent iron and rust issues that challenge your household system.

Source: USGS groundwater sampling. Sampled 2017-07-19. 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.
