Sample Depth, Well Depth, and Source Type Influence Expectations
Consider the aquifer source depth compared to your well depth
The U.S. Geological Survey collected samples from wells approximately 83 feet deep in aquifer 112ICCC in Rockingham County. If your well is notably shallower or deeper, your water quality may differ from this regional data.
Understand that these measurements reflect an area, not your specific well
The data represent regional groundwater conditions but do not specify your own water’s composition. A local test is necessary to identify the exact constituents present in your household supply.
What Regional Sampling Terms Mean in Context
Detected means the constituent was measurable, not a violation
Every iron measurement in the area showed detection at some level. Detection simply means instruments found iron; it does not indicate unsafe or noncompliant water.
Median and range provide a spread of measurements taken over time
The median iron concentration among sampled wells was 235.0 micrograms per liter, with results ranging from 0.016 to 327.0 micrograms per liter. These numbers describe the typical and extreme values found in the area but do not diagnose your well.
Interpreting the Record’s Median and Range as a Homeowner
Median reflects a central tendency of local groundwater iron levels
If your well’s iron concentration is near the median, you might expect moderate levels of iron presence, which can affect water color and taste to some degree.
The range indicates iron can be present at very low up to higher concentrations
Because the range extends from barely detectable to relatively higher values, your well’s iron levels could vary widely within this scope, underlining the importance of testing your own water supply.
Consequences of Leaving Complete Well Water Untreated
Iron presence, if untreated, may cause staining and discoloration over time
Iron in water can lead to reddish or brownish stains on fixtures, laundry spotting, and an altered taste, although these effects vary with concentration and exposure.
Untreated conditions might increase maintenance needs for plumbing and appliances
Accumulated iron deposits can reduce efficiency of water-using appliances and clog pipes eventually if no treatment is used to address the issue.
Matching Treatment Capacity to Household Water Use
Assess daily household water demand when choosing a treatment system
A system should provide ample grain capacity to handle iron removal given the household’s water consumption patterns. For example, the Fleck Complete Well System offers a 32,000 grain capacity suitable for many residential needs.
Consider how peak usage affects treatment effectiveness and system sizing
High water use periods require sufficient system capacity to maintain treated water flow and quality without interruption or decline.
These observations are based on 53 groundwater samples from one well in Rockingham County’s aquifer 112ICCC collected between 2014 and 2019, as documented by the U.S. Geological Survey.
For your specific water conditions, testing your own well is essential. The Fleck Complete Well System ships ready to configure for residential water treatment need and can address iron and related concerns referenced in the regional data.
