What the Measured Range Means Against Federal Standards, and What It Does Not Mean
Laboratory reports for groundwater in Coconino County’s aquifer 310COCN show iron detected in all sampled wells between 1.0 and 4,543.0 micrograms per liter (ug/L), with a median of 1,800.0 ug/L. None of these results exceed any federal health-based standards. That means detection signifies the presence of iron, but not a violation or unsafe condition. Iron levels are often measured for aesthetic secondary standards related to taste, staining, and metallic flavor, not health risk.
What 'Detected,' 'Median,' and 'Range' Mean in These Sampling Records
'Detected' means the instruments identified iron in every sample tested across three wells from July 2017 through April 2026, at depths between 600 and 1,150 feet. The 'median' of 1,800.0 ug/L indicates the middle value of all detected samples, not an average of your own well water. The 'range' from 1.0 to 4,543.0 ug/L reflects variability within the aquifer tested, not a guarantee for your household supply.
How Public-System Records Differ from Private-Well Testing in What They Establish
These government-monitoring results represent area-wide well samples, not individual household wells. While useful for understanding broad aquifer conditions, they cannot replace a specific test for your water before sizing treatment. The only way to determine your water’s actual iron concentration and other characteristics is through laboratory analysis of your well water itself.
How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
Using the Fleck Complete Well System, which ships ready to configure and has a treatment capacity of 32,000 grains, iron and other common groundwater constituents causing discoloration or staining are addressed effectively. Treated water at the tap typically shows improved clarity, reduced staining potential on fixtures, and better taste, aligning with the goals of household water treatment for complete wells.
How to Judge Treatment Capacity Against Your Household’s Daily Demand
Sizing the Fleck Complete Well System requires knowing your household’s daily water use and iron concentration from your own water test. Capacity at 32,000 grains can handle moderate iron loading before regeneration or maintenance is needed. Larger or higher-demand households may require more frequent regeneration or multiple units configured accordingly. Compare your water test iron levels and average daily gallons used to ensure appropriate capacity.
What You Should Write Down Before Asking for Treatment Advice
- Your well water iron concentration from a certified laboratory report
- Your household’s typical daily water usage in gallons
- Any known water quality issues besides iron, such as manganese or hardness
- Depth and flow rate details of your well, if available
Having these details will support accurate treatment sizing and product recommendations tailored to your complete well water needs.
In summary, area aquifer data provide helpful context but cannot replace a direct analysis of your household water. Making treatment decisions involves understanding detection versus standards, measuring your specific water quality, and matching treatment capacity to usage. The Fleck Complete Well System offers an effective, configurable solution aligned with these requirements.

Source: USGS groundwater sampling. Sampled 2026-04-30. 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 310COCN aquifer (Coconino County): 19 results from 3 wells, median 1800.0 ug/L, range 1.0-4543.0 ug/L; none above any federal threshold
