1. What an Iron Concentration Lab Report Shows
A laboratory test report for iron concentration in water gives a numeric value representing micrograms per liter (ug/L) of iron detected in a specific water sample. This report lists precise figures from individual tests of a single well or tap water, reflecting iron present at that moment for that source alone.
2. Understanding Detected, Median, and Range in Local Sampling
The U.S. Geological Survey sampled 62 results from 42 wells in Broward County’s aquifer 112BSCNN between March 2010 and November 2020. Iron was detected in 59 results, indicating iron’s presence in most wells sampled. The median iron concentration—502.0 ug/L—represents the middle value when these results are arranged by concentration, offering a typical level across this dataset. Range spans from the lowest detected (3.5 ug/L) to the highest (4600.0 ug/L). None exceeded federal health-based limits, confirming that these detections do not indicate unsafe water quality by legal standards.
3. Reading the Data as a Broward County Homeowner
Imagine your well’s iron concentration falls anywhere within this range. The median suggests that about half the area’s wells sample iron below or above 502.0 ug/L. This spread signals that iron presence is variable across locations and depths, from 10 to 152 feet deep where wells were sampled. Your own well’s iron level can differ significantly; only direct testing of your water reveals your specific condition.
4. Comparing Broward County to Neighboring Areas Without Overreading
Iron levels in Broward County’s aquifer provide a localized snapshot for 112BSCNN. Neighboring counties may have different geological features affecting iron concentrations. While the presence of iron bacteria might also be expected in similar aquifers nearby, differences in median levels and ranges are natural due to varying soil, rock composition, and water table depths. Use these data as a regional guide, not as a direct proxy for your exact water quality.
5. Aesthetic Secondary Standards Versus Health-Based Limits for Iron
Federal secondary standards address iron for reasons like staining, taste, and coloration—qualities typically driving residential concerns. These are not health risk thresholds. Broward County sampling shows iron levels detected are below health-based legal thresholds. This means any iron-related taste or staining issues, often linked to iron bacteria, involve aesthetic considerations and operational impact on household water systems instead of safety concerns.
6. Public System Data Compared to Private Well Testing
Public system water quality records represent treatment and source water monitoring aimed at compliance with health regulations. They may not capture localized variations in private wells. Private well owners in Broward County should conduct their own iron and iron bacteria tests for an accurate picture of their specific water condition. Public data helps understand regional tendencies but does not substitute for private well analysis.
In summary, the U.S. Geological Survey’s decade-long sampling of Broward County aquifer 112BSCNN wells shows iron presence is common but within health limits. This record covers multiple wells across the area, not individual homes or wells. For residences facing iron bacteria issues, the C-Series Iron Bacteria & Slime Filter ships ready to configure and provides targeted control where treatment is warranted.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2020-11-19. 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.
On record: U.S. Geological Survey sampling of Iron in the 112BSCNN aquifer (Broward County): 62 results from 42 wells, median 502.0 ug/L, range 3.5-4600.0 ug/L; none above any federal threshold
