Understanding 'Detected,' 'Median,' and 'Range' in This Manganese Sampling Record
The manganese measurements provided here come from 20 samples taken from three wells in Coconino County within aquifer 310COCN. These samples were collected between July 2017 and April 2026 at depths from 600 to 1150 feet. The term 'detected' means manganese was measurable in every sample. The 'median' value of 105.5 micrograms per liter (ug/L) represents the middle point of manganese levels measured, with half the samples below and half above this concentration. The 'range' from 39.0 to 410.0 ug/L shows the lowest and highest manganese amounts found in these wells. Importantly, these results do not indicate any sample exceeded federal manganese thresholds; detection does not imply a violation or unsafe condition.
Additional Considerations for Commercial or Industrial Operators
Households focus mainly on aesthetic concerns like staining and taste, but commercial or industrial users may have questions about manganese's impact on process efficiency, equipment longevity, and regulatory compliance. Operators in these sectors should consider how manganese levels could interfere with manufacturing systems or product quality, possibly requiring more rigorous testing or treatment approaches specific to their operations. Residential water concerns typically do not extend to these operational variables.
How Sampling and Well Depth Influence What to Expect in Your Water
The depth at which wells are sampled can affect manganese concentrations. These samples came from wells between 600 and 1150 feet deep, representing deeper groundwater in Coconino County. Groundwater manganese levels can vary by depth due to geological conditions and oxygen availability. If your own water source is shallower or from a different aquifer, your manganese levels could differ. To confirm your household’s specific condition, testing your own well or tap water is necessary.
Comparing Coconino County’s Manganese Data Without Overreading
When looking at manganese data from nearby counties, differences in geology and groundwater sources mean levels can vary widely. It is important to view Coconino County data as specific to aquifer 310COCN rather than universally representative of all local wells or regions. Avoid assuming your water matches these findings exactly; instead, use this regional data as a context for understanding potential manganese presence in your area.
Maintenance Rhythm of the Autotrol Black Manganese Stains Filter
The Autotrol Black Manganese Stains Filter reliably addresses manganese-related aesthetic issues such as staining and discoloration. This equipment ships ready to configure for residential water systems. Regular maintenance involves scheduled media replacement and periodic backwash cycles to renew filtering capacity; these tasks are straightforward to perform with customer instructions. Consistent upkeep ensures the filter maintains its effectiveness against manganese build-up without needing professional service calls.
Fixtures and Appliances Most Affected by Manganese
Manganese in water commonly causes staining on sinks, bathtubs, and toilets, often appearing as dark brown or black marks. These stains can be difficult to remove and may worsen over time if untreated. Appliances such as dishwashers and washing machines may also accumulate deposits that affect their appearance and function. Water-using fixtures that rely on clear, stain-free water will show effects first, making them key indicators of manganese presence in household water.
This briefing reviewed what manganese detections in Coconino County’s aquifer 310COCN represent and what they do not. Understanding these regional sampling results helps households decide when testing their own water is needed and how to manage manganese-related issues effectively with appropriate filtration technology.
Where this information comes from
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 Manganese in the 310COCN aquifer (Coconino County): 20 results from 3 wells, median 105.5 ug/L, range 39.0-410.0 ug/L; none above any federal threshold
