Water drawn from Lee County's aquifer 230SDMR travels through underground rock layers before reaching residential wells. This aquifer has been sampled and studied by government agencies to provide insights on arsenic levels in the area, but individual well testing remains essential to know specific home water quality.

1. What a Certified Laboratory Test for Arsenic Reports and How to Read It

Typical reporting includes numerical concentrations in micrograms per liter (ug/L).

Results often show whether arsenic is detected; detection only confirms presence, not a health violation.

Federal health standards set a maximum contaminant level (MCL) for arsenic, with no results in Lee County’s 230SDMR aquifer exceeding this limit in government samples.

Test reports usually specify sample depth and date, important context for comparing results.

2. A Worked Example: Reading Lee County’s Median and Range

Sampling of nine wells between May and June 2012 showed arsenic detection in all samples from 0.14 to 4.8 ug/L.

The median arsenic concentration was 1.1 ug/L, indicating half the samples measured below this level and half above.

No individual sample in this set surpassed the federal arsenic MCL, demonstrating local aquifer conditions but not a guarantee for any specific well.

Sample wells ranged 100 to 325 feet deep, reflecting typical residential well depths in the area.

3. How the Fleck Arsenic Filter Removes or Neutralizes Arsenic

This filtration system is designed to reduce arsenic concentration by passing water through specialized media that adsorb arsenic compounds.

The Fleck System's operation does not rely on chemicals but mechanical filtration processes.

It ships ready to configure for household use, allowing direct purchase with no additional setup service required.

Regular testing of treated water is recommended to verify arsenic reduction remains effective over time.

4. How to Judge Treatment Capacity Against Household Daily Water Demand

Consider average daily water use to ensure the filtration system can handle household volume without reducing flow.

System capacity should accommodate peak use days, factoring in number of residents and typical consumption patterns.

Matching filter media life and throughput with household demand helps maintain consistent arsenic removal.

Planning for maintenance intervals supports ongoing treatment effectiveness.

5. How Many Samples and Wells Stand Behind These Figures and What a Small Sample Means

Nine wells sampled provide a limited but useful snapshot of local arsenic levels in the 230SDMR aquifer.

Sampling dates clustered within a month in 2012 reflect conditions at that time, which may vary naturally over years.

Well depths from 100 to 325 feet cover a typical residential range but do not guarantee identical arsenic levels in all wells.

Small sample size means individual households must measure their own well water to obtain accurate arsenic data.

Choosing a water treatment approach involves understanding local arsenic data, interpreting certified test results correctly, and matching household water use to treatment system capacity. The Fleck Arsenic Filter offers a documented mechanical method to reduce arsenic, providing a practical option for households in Lee County’s aquifer 230SDMR area.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-06-08. 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 Arsenic in the 230SDMR aquifer (Lee County): 9 results from 9 wells, median 1.1 ug/L, range 0.14-4.8 ug/L; none above any federal threshold
