1. How sample depth, well depth or source type changes what a reader should expect
The U.S. Geological Survey collected iron samples from 22 wells within Washington County, Nebraska, focusing on aquifer 112SDGVD. These wells were 25 to 249 feet deep, reflecting typical groundwater sources for area households. Water quality can change by well depth because iron often dissolves from soil and rock layers differently at various depths. Shallow wells might show different iron concentrations than deeper ones. Since this data represents an area-wide aquifer sample, it provides a broad picture of the range and median iron levels in groundwater available for residential use but does not pinpoint any individual well’s condition or iron content.
2. Maintenance rhythm of the documented technology in plain terms
Addressing iron and rust in a home’s water supply often leads homeowners to consider technical treatment. The C-Series Orange Iron & Rust Stains Filter ships ready to configure for household use and requires routine upkeep for sustained effectiveness. Typically, maintenance includes periodic filter media replacement or regeneration to maintain iron removal capacity and prevent rust staining. This rhythm depends on water usage volume and iron concentration but generally involves predictable intervals rather than frequent or complex servicing. Understanding this routine helps households plan for ongoing care without surprises.
3. A worked example: reading the record's median and range as a homeowner would
In the Washington County aquifer sampling data, the median iron concentration was 1,185 micrograms per liter (ug/L), with results spanning from as low as 3.3 ug/L to as high as 11,800 ug/L. For a homeowner, this means typical iron levels can vary widely depending on which well supplies their water. Median values represent a middle point in the data set, suggesting many wells have iron near 1,185 ug/L while others are notably lower or higher. This broad range illustrates why individual water testing is necessary to determine a specific household’s iron condition. These figures are detections only, not violations or safety limits, and simply describe what instruments measured in area wells.
4. What 'detected', 'median' and 'range' mean in the sampling record on this page
The term 'detected' means the measurement instrument identified iron present at quantifiable levels in 78 of 85 samples. It does not mean any health or safety violation, only that iron is present at some concentration. The 'median' is the middle value of the collected iron concentrations and helps summarize what is typical for the area. The 'range' shows the lowest and highest detected values to convey variability across different wells. No single measurement from this record exceeds federal thresholds, confirming the area’s iron presence is within regulatory parameters. These terms frame how to interpret government-collected water data without assuming any individual well matches these values exactly.
5. How seasonal or multi-year variation shows in the record (dates and ranges given)
The sampling took place from August 11, 2010, to April 15, 2026, reflecting over 15 years of data. This multi-year spread helps reveal how iron concentrations may fluctuate with seasonal cycles or longer-term environmental changes. Factors such as groundwater recharge rates, weather patterns, and aquifer chemistry can influence iron presence over time. The wide range of iron results within this period indicates that individual well water might show variation year to year or season to season. Homeowners should consider periodic testing for their well water to track any changes in iron that could affect household water quality.
In summary, the groundwater sampling record for Washington County aquifer 112SDGVD shows varying iron levels in area wells at depths relevant for residential water. These findings do not represent any single home’s water but offer a benchmark for understanding local groundwater characteristics. The C-Series Orange Iron & Rust Stains Filter is a documented option that ships ready to configure and can help manage iron and rust issues at home with a clear maintenance routine.
