Understanding Water from Aquifer 111ALVM in Keith County

The groundwater in Keith County typically flows from the aquifer known as 111ALVM, supplying residential wells 17 to 33 feet deep. Water from this aquifer reaches household taps after passing through local soil and rock formations, which influence its mineral content, including fluoride levels.

1. Treatment Capacity vs. Household Demand

Match filter capability to your daily water use

Estimate your household’s average daily water consumption, including drinking, cooking, and bathing needs. The treatment system you select must have the capacity to process this volume effectively to maintain desired fluoride levels.

Consider flow rates typical for residential use

Ensure that the treatment device accommodates typical household water flow without reducing pressure or causing system backups.

2. Ruling Out Causes in Order – From Basic Checks to Lab Tests

Verify your water source

Confirm your well draws from the 111ALVM aquifer or a known alternative to understand potential fluoride presence better.

Look for changes over time in water taste or staining

While fluoride itself is tasteless and does not stain, changes in water quality might indicate other mineral variations.

Request a laboratory fluoride test specific to your well water

Only a certified laboratory test of your own water sample can identify your water’s exact fluoride concentration.

3. What Government-Measured Fluoride Levels Mean and Do Not Mean

Measured fluoride in Keith County aquifer 111ALVM ranges from 0.41 to 2.74 mg/L

This range reflects multiple samples taken from four wells between 2010 and 2023. All results remain below federal fluoride thresholds established for safety.

A detection is not a health violation or proof of unsafe water

Detecting fluoride means instruments measured it; it does not mean your water is unsafe or violates any legal limit.

4. Additional Questions for Commercial or Industrial Users

Assess fluoride impact on manufacturing or processing

Facilities may require detailed fluoride data to comply with process specifications or product purity standards.

Consider the volume of water used daily

Large-volume users should evaluate the capacity and maintenance requirements of fluoride treatment systems more thoroughly than households.

5. Difference Between Aesthetic Secondary Standards and Health-Based Limits for Fluoride

Aesthetic guidelines focus on taste and appearance

Fluoride levels affect water taste and may cause mild staining but are regulated separately from health-based standards.

Health-based federal standards ensure safety up to specified limits

The fluoride concentrations measured in Keith County are below levels that federal authorities have set to protect health.

6. Seasonal and Multi-Year Variation in Fluoride Levels

Sampling dates cover 2010 to 2023, showing consistency

Data from nine samples over more than a decade indicate that fluoride levels in this aquifer remain relatively steady, without large seasonal swings.

Range shows natural variation between wells and times

Variations from 0.41 to 2.74 mg/L reflect differences in local geology and water movement rather than short-term fluctuations.

Summary and Next Steps

Government sampling of groundwater wells in Keith County’s aquifer 111ALVM shows fluoride detected in all samples with values between 0.41 and 2.74 mg/L, all below federal thresholds. These findings apply to the sampled wells, not your specific well water. To determine your household water’s fluoride level, obtain a certified laboratory test of your water. Matching treatment capacity to your water demand is essential, and after confirming your water’s fluoride concentration, the Pentair Fluoride Filter ships ready to configure and can help reduce fluoride if desired. The full government data is available through the U.S. Geological Survey monitoring location 410251102024201.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2023-07-11. 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 111ALVM aquifer (Keith County): 9 results from 4 wells, median 1.4 mg/L, range 0.41-2.74 mg/L; none above any federal threshold
