The U.S. Geological Survey tested fluoride levels in 17 wells across Plymouth County's 112SRFD aquifer from 2010 to 2019. Among 35 samples, fluoride appeared in 21 results at concentrations ranging from 0.01 to 0.41 mg/L, with a median of 0.04 mg/L. Importantly, none of these measurements exceeded any federal health-based standards.
Fixtures and Uses Affected by Fluoride First
Drinking Water and Ice Makers
Fluoride is most noticeable where water is consumed directly, such as drinking faucets and ice makers, due to its taste and potential dental effects.
Kitchen Appliances Using Water
Appliances like coffee makers can reflect fluoride presence over time through taste changes or mineral buildup.
Bath and Laundry Fixtures
Fluoride does not usually affect bathing or laundry water visibly but is present consistently if in the source.
Differences Between Public Water Records and Private Well Testing
Public System Records Represent Area Wide Sampling
USGS data reflect multiple wells in the Plymouth County 112SRFD aquifer but do not apply to any single homeowner’s well or tap water directly.
Individual Wells Require Specific Testing
To understand fluoride levels in your household water, a certified laboratory fluoride test on your well or tap water is necessary.
Public Data Do Not Indicate Safety or Violations
Detection in government records indicates measurements found fluoride; it does not represent a health violation or unsafe condition.
Interpreting Median and Range as a Homeowner
Median Fluoride Level Is 0.04 mg/L
This means half of the detected samples had fluoride at or below this concentration, suggesting low typical levels in the aquifer.
Range Extends to 0.41 mg/L
The highest detected fluoride measurement in the area remains below federal thresholds, showing occasional variation.
Detections and Non-Detections
Some samples showed fluoride below reporting limits, indicating variability in the aquifer or measurement sensitivity.
Judging Treatment Capacity Against Household Demand
Estimate Daily Water Use
Calculate total daily household water consumption to assess treatment flow and capacity needs.
Consider Peak Usage Times
Identify high-demand periods, such as mornings, to size treatment appropriately for effective fluoride reduction.
Allow for Future Changes
Factor in potential household growth or increased water use to ensure treatment sufficiency over time.
Information to Record Before Seeking Treatment Advice
Water Source Details
Note if your water comes from a private well or public system and the depth or aquifer if known.
Test Results with Dates
Keep copies of certified laboratory analyses for fluoride and other constituents relevant to your water quality.
Household Water Usage
Document average and peak water consumption volumes and any appliance requirements.
Seasonal and Multi-Year Fluoride Level Variations
Data Span Nine Years Showing Consistency
Sampled fluoride levels from June 2010 to September 2019 exhibit no upward trend or breach of federal standards.
Seasonal Differences Are Not Prominent
The sampling dates cover different months without significant seasonal fluctuation in fluoride concentrations.
Long-Term Monitoring Supports Treatment Decisions
This record provides a stable overview to inform whether enhanced fluoride reduction is necessary relative to household needs.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-09-05. 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 (Plymouth County): 35 results from 17 wells, median 0.04 mg/L, range 0.01-0.41 mg/L; none above any federal threshold
