If you notice any unusual fluoride-related characteristics in your water—such as taste changes or residue—you are responding to a known regional pattern. In Graham County, the U.S. Geological Survey sampled 7 wells from 2010 to 2014 in the N100BSNRGB aquifer, recording fluoride concentrations between 0.34 and 8.7 mg/L, with a median of 0.67 mg/L. Among these, some readings exceeded the federal maximum contaminant level (MCL) of 4.0 mg/L established to protect health. However, these values reflect area-wide data and do not specifically describe your household water without a certified laboratory test.
Understanding a Certified Fluoride Lab Test for Your Household Water
Certified Laboratory Results Report Concentration in mg/L
A certified test will provide a fluoride concentration expressed in milligrams per liter (mg/L), directly comparable to federal health standards. Reading these results helps determine whether your water requires treatment beyond aesthetic considerations. Because the federal MCL for fluoride is 4.0 mg/L, results above this level suggest consultation with a water treatment professional or further investigation.
Testing Identifies Your Specific Well or Tap Water Condition
The regional sampling data cannot substitute for a test of your own well or municipal supply. To know your household’s fluoride level accurately, obtain a laboratory test specific to your water source. Local government health departments or certified water testing services can facilitate such testing.
How Fluoride Enters Groundwater in Graham County’s Aquifer
Natural Geological Sources in the Aquifer
Fluoride occurs naturally in bedrock and sediments of the N100BSNRGB aquifer. Its concentration in groundwater depends on the local mineral composition and the depth of the water source, with sampled wells ranging from 83 to 1200 feet deep. Higher levels in some samples indicate that geological variability influences fluoride presence.
Local Hydrogeology Drives Fluoride Variation
Changes in groundwater flow, recharge events, and rock-water interactions cause fluoride levels to fluctuate between wells and over time. Understanding these natural processes is crucial to interpreting test results correctly.
Role of Household Plumbing Materials and Age—Separate from Aquifer Fluoride Content
Plumbing Does Not Add Fluoride to Water
Fluoride concentrations measured in water originate from the source aquifer or supply system, not from household plumbing materials or age. While older plumbing can affect other water quality aspects, it does not influence fluoride content.
Corrosion or Material Interactions Are Not a Fluoride Source
Common plumbing materials in Graham County homes do not release fluoride through corrosion or leaching. Therefore, plumbing replacement will not alter fluoride levels but may address other water quality issues.
Changes at the Tap After Using the Fleck Fluoride Filter
Reduced Fluoride Concentration in Treated Water
The Fleck Fluoride Filter ships ready to configure to remove or reduce fluoride presence effectively from residential water. After treatment, water at the tap should have a significantly lower fluoride concentration compared to untreated source water, improving safety and taste if fluoride was elevated.
Maintains Overall Water Quality While Targeting Fluoride
This system specifically targets fluoride without adversely affecting beneficial minerals or the overall chemistry of your water supply.
How the Fleck System Addresses Fluoride
Filtration Technology Designed for Fluoride Removal
The system uses a documented process to reduce fluoride by adsorption or ion exchange mechanisms, tailored to handle concentrations detected in Graham County’s aquifer. Its design allows consistent performance across a range of fluoride levels reported by the USGS.
Direct Purchase Enables Home Configuration
The Fleck Fluoride Filter is available for direct purchase and ships ready to configure for household use, giving homeowners control over managing fluoride without relying on third-party services.
In summary, government data from Graham County’s aquifer show fluoride concentrations varying from low to levels exceeding the federal health threshold. To know your household water’s fluoride concentration, a certified laboratory test is necessary. For effective reduction, the Fleck Fluoride Filter offers a targeted solution designed to lower fluoride concentrations at your tap.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-11-20. 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 Fluoride in the N100BSNRGB aquifer (Graham County): 29 results from 7 wells, median 0.67 mg/L, range 0.34-8.7 mg/L; 9 above a health-based federal MCL (federal MCL 4.0 mg/L)
