1. Seasonal and Multi-Year Variation in Radon Measurements

Sampling Dates Span Nearly Two Years

Radon levels in Cape May County's aquifer 121CKKD were sampled from October 12, 2022, to July 2, 2024, covering multiple seasons and nearly two years.

Consistent Detection Across All Samples

Radon-222 was detected in all 8 results from 3 separate wells, with no samples below the reporting limit, indicating persistent presence in groundwater at these locations.

Range of Radon Values Reflects Natural Variation

Measurements ranged from 50.0 to 88.0 picocuries per liter (pCi/L), showing some natural fluctuation but no values exceeding federal thresholds.

2. What a Certified Laboratory Test Reports and How to Interpret It

Report Includes Radon Concentration in Picocuries per Liter

A laboratory-certified radon test for household water will state the radon concentration, usually in pCi/L, which quantifies the radioactive gas present.

Detection Does Not Imply a Violation or Unsafe Condition

Detected radon means the gas is measurable, but values below federal thresholds found in this area are not violations or health-based limits.

Testing Your Own Well Is Essential for Accurate Information

Because regional data cannot specify individual water quality, testing your household’s well water at a certified lab is necessary to know your radon levels precisely.

3. Questions Relevant to Household Water Use (Excluding Commercial Considerations)

What Volume of Water Does Your Household Use Daily?

Knowing your daily water demand helps determine the capacity needed for radon treatment systems designed for residential use.

Does the Existing Equipment Handle Peak Usage Efficiently?

Assess whether your current system manages peak water flows or if capacity upgrades are needed for consistent radon reduction during high usage.

Is Your Treatment Solution Suitable for Radon Specifically?

Make sure the technology targets radon removal effectively rather than general water treatment to address this specific constituent.

4. Reading the Median and Range as a Homeowner

Median Radon Level Indicates Typical Concentration

The median radon concentration of 65.0 pCi/L from sampled wells suggests a common occurrence level in the area’s groundwater.

Range Defines the Likely Variation

Understanding the range from 50.0 to 88.0 pCi/L helps anticipate the fluctuation you might see in your own water over time.

No Sample Exceeded Federal Radon Limits

This record shows none of the values surpassed federal action levels, indicating the aquifer generally stays within regulatory boundaries.

5. Judging Treatment Capacity for Household Water Demand

Match System Capacity to Your Household’s Daily Water Use

Treatment solutions like the Autotrol Radon in Water Filter ship ready to configure for various flow rates to accommodate different household demands.

Ensure Suitable Capacity for Peak and Average Usage

Since radon concentration can vary, selecting treatment capacity that covers both regular and peak usage helps maintain consistent water quality.

Consider Future Water Use Changes

Planning for potential increases in water use can prevent undercapacity and support ongoing radon mitigation effectiveness.

These findings apply to Radon-222 results from groundwaters sampled in Cape May County’s aquifer 121CKKD between 2022 and 2024, based on data from the U.S. Geological Survey (https://waterdata.usgs.gov/monitoring-location/391100074510802/).

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-07-02. 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 Radon-222 in the 121CKKD aquifer (Cape May County): 8 results from 3 wells, median 65.0 pCi/L, range 50.0-88.0 pCi/L; none above any federal threshold
