Public Water System Records Are Not the Same as Testing Your Own Well
Water-quality measurements from Rockingham County’s aquifer 112ICCC, provided by the U.S. Geological Survey, represent samples taken from specific wells in the area—not from individual household wells or taps. These results describe what has been detected in the aquifer under general conditions but cannot specify the exact composition of water at your home. To know your household’s water quality, a private well test through a certified laboratory is essential.
How Iron Enters Rockingham County’s Groundwater and Distribution System
Iron in natural groundwater often originates from minerals in soil and rock. In Rockingham County’s aquifer 112ICCC, the iron detected comes from natural geologic processes over time that dissolve iron-bearing materials into the water. Public distribution systems may also introduce iron through aging pipes or infrastructure, but the primary source in this region’s groundwater is geologic material interacting with water underground.
Steps to Narrow Down Issues Before Laboratory Testing
If you experience hard water and iron-related effects like staining or metallic taste, a systematic approach helps identify the cause. Start by checking visible signs such as discoloration or buildup on fixtures and appliances. Next, consult your water supplier’s public water quality report for general area data. Finally, for precise results relevant to your household, arrange a comprehensive well or tap water test at an accredited laboratory, including iron concentration and hardness measurements.
What the Iron Measurements Mean in Relation to Federal Thresholds
The U.S. Geological Survey data for Rockingham County’s 112ICCC aquifer show iron concentrations ranging from 0.016 to 327.0 micrograms per liter, with a median of 235.0 micrograms per liter across 53 samples. All measurements are below federal secondary maximum contaminant levels, which are advisory taste and staining guidelines rather than health-based standards. Detection of iron at these levels does not indicate a violation or unsafe water but may contribute to aesthetic issues typical of hard water and iron presence.
Sample Size and Scope: Interpreting Data from 53 Results in One Well
This data set reflects 53 separate samples from one well drilled to approximately 83 feet. While it offers useful insights into iron presence in Rockingham County’s aquifer 112ICCC, relying on a single well limits broader generalizations. A small sample size means local variations are possible. Households using different wells or municipal sources should consider this when comparing their water quality to these figures.
Determining the Right Treatment Capacity for Your Home’s Demand
When addressing hard water and iron-related issues in a residential setting, sizing treatment equipment properly ensures effective operation. The Pentair City Hard Water + Iron System ships ready to configure and handles a grain capacity of 32,000. Assess your average daily water use and the severity of hardness and iron levels from testing to choose equipment that matches your household’s needs without over- or under-sizing.
In summary, the U.S. Geological Survey’s sampling from one well in Rockingham County’s aquifer 112ICCC shows consistent detection of iron well below any federal secondary maximum contaminant level. These regional measurements provide context but are not a substitute for testing your individual water source. To properly manage hard water and iron at home, base your decisions on specific water testing and select treatment capacity accordingly.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-08-22. 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 112ICCC aquifer (Rockingham County): 53 results from 1 wells, median 235.0 ug/L, range 0.016-327.0 ug/L; none above any federal threshold
