What the Measured Fluoride Range Means and Does Not Mean

Government Sampling Findings

The U.S. Geological Survey collected groundwater samples from three separate wells in Merrimack County's aquifer 112SRFD between June 2011 and October 2019. The median fluoride concentration found was 0.04 mg/L, with a range from 0.04 to 0.05 mg/L detected in wells 28 to 49 feet deep.

Comparison to Federal Standards

None of these sample results exceeded any federal fluoride threshold. This means the government monitoring in the aquifer area does not show fluoride concentrations above levels set for health-based standards. However, these figures do not confirm the fluoride level present in any individual household well or tap water.

What This Does Not Confirm

Since these data represent only sampled wells in the area aquifer, they cannot determine your home's precise fluoride content. Actual fluoride measurement requires water testing specific to your well or water supply.

The Role of Plumbing Material and Age, Separate from the Source Water

Influences Beyond the Aquifer

Materials in household plumbing such as pipes, fixtures, and fittings can affect water quality separately from fluoride levels in source water. Changes in plumbing condition or age do not alter fluoride concentration but may impact other water characteristics.

After Treatment Equipment Failure

When existing fluoride treatment equipment stops functioning, any removal of fluoride previously achieved halts. Plumbing does not substitute for treatment in reducing fluoride content.

What Happens When This Problem Is Left Untreated for Years

Long-Term Fluoride Presence

Without treatment, fluoride present in source water remains unchanged over time. The area sampling shows fluoride at low levels, which are consistent and stable. Long-term exposure to fluoride at or below federal standards is generally regarded as safe, but individual concerns should prompt water testing.

Importance of Testing

To understand your household's fluoride condition after treatment failure, water testing is necessary. This provides accurate measurement essential for making informed decisions on next steps.

What Changes for a Large Household, a Second Home, or a Seasonal Property

Variations in Water Use

Larger households or properties with intermittent use do not impact fluoride concentration in source water. However, water stagnation in plumbing during long absences may influence water quality unrelated to fluoride.

Planning for Multiple Residences

For second homes or seasonal properties, testing water fluoride upon return can help assess current conditions, since treatment equipment malfunction may have lasted through periods of vacancy.

The Household or Facility Symptoms That Do and Do Not Point to This Problem

Symptoms Linked to Fluoride

Fluoride itself is colorless and tasteless in water; it does not cause visible staining or odor. Concerns about fluoride generally relate to health or regulatory levels rather than sensory indicators.

Non-Fluoride Water Issues

Staining, unpleasant taste, or discoloration often arise from minerals other than fluoride or from plumbing materials.

How Seasonal or Multi-Year Variation Shows in the Record

Stable Fluoride Measurements

The USGS sampling over an eight-year period shows consistent fluoride concentrations between 0.04 and 0.05 mg/L. This indicates stable fluoride presence in the aquifer without significant seasonal or multi-year variation.

Implications for Water Quality Monitoring

While area fluoride levels remain steady, household water quality can fluctuate due to local factors requiring individual testing for precise assessment.

Conclusion

If fluoride treatment equipment has failed and you want to manage fluoride levels in your household water, consider the Autotrol Fluoride Filter. This system ships ready to configure and is designed to address fluoride presence informed by water testing results matching your home's demand.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-10-08. 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 112SRFD aquifer (Merrimack County): 6 results from 3 wells, median 0.04 mg/L, range 0.04-0.05 mg/L; none above any federal threshold
