1. Interpreting Federal Standards and Measured Range

Detected Alpha Particles Are Not Violations

In Calcasieu Parish’s aquifer 11202LC, USGS groundwater sampling found alpha particle activity ranging from 0.3 to 5.3 pCi/L with a median of 1.9 pCi/L. None of these measurements exceed the federal action level for combined uranium and radium alpha activity, which means these results do not indicate a regulatory violation in the sampled wells.

Range Reflects Naturally Occurring Variation

The range and median represent what was measured in a few specific wells, not a uniform condition. This variation is common across groundwater sources and does not reflect a specific well’s current condition.

2. Comparing Local Records with Neighboring Counties

Do Not Assume Similar Levels Elsewhere

Records from Calcasieu Parish show certain uranium-radium activity levels, but neighboring counties with different geology can show different ranges. Direct comparison has limited use without knowing local aquifer characteristics.

Use Area Data as General Context Only

These measurements provide regional insight but cannot replace individual well testing to understand personal water quality.

3. Consequences of Leaving Uranium-Radium Untreated

Long-Term Exposure Considerations

Extended presence of uranium and radium in drinking water, if above safe levels, can pose health concerns. The sampled values here are below federal action thresholds, but testing your home water is necessary for specific risk assessment.

Potential for Taste and Corrosion Effects

While uranium and radium themselves do not affect taste or appearance, associated minerals may impact plumbing and water quality if untreated.

4. Changes To Water After Using the Pentair Uranium & Radium System

Reduction of Alpha Particle Activity

The Pentair Uranium & Radium System is designed to reduce uranium and radium levels by removing alpha particle activity from water, directly addressing this type of contamination.

Clear Water with No Added Chemicals

The treated water from this system will appear unchanged in taste and odor but will have lower uranium-radium-related radioactivity.

5. Steps To Confirm and Address Uranium-Radium

Start with a Certified Laboratory Test of Your Water

Because area data cannot determine your well’s condition, a water analysis focusing on radioactivity is essential before considering treatment.

Rule Out Other Causes of Water Quality Issues

Before treatment, check for other water quality factors like hardness or pH that might influence overall system performance.

6. Extent and Limits of Recorded Sampling

Small Sample Size from Four Wells

The USGS data for Calcasieu Parish aquifer 11202LC is based on eight results from four wells sampled between July and December 2020. This limited sample represents a snapshot rather than comprehensive coverage.

Sampling Depths Between 110 and 260 Feet

The wells sampled are moderately deep, but other well depths could yield different results, so local variation is expected.

Closing Reminder: What Not to Conclude from Area Data

These regional uranium-radium measurements do not establish your home’s water quality. Testing your own water is the only way to know your specific uranium-radium levels. If treatment is needed, equipment like the Pentair Uranium & Radium System ships ready to configure for residential use, offering targeted reduction of these constituents.
