Introduction: What Area Radon Data Can and Cannot Reveal for Your Household

Government sampling by the U.S. Geological Survey measured radon-222 in the Greene County aquifer with results from three wells, showing detections between 200 and 450 picocuries per liter (pCi/L) and a median of 290 pCi/L. These data reflect regional groundwater conditions but do not indicate the specific radon level in your well. Each property's water can vary, so local results provide context rather than a definitive measure of your home's water quality.

1. What to Record Before Seeking Treatment Advice

Before considering any treatment options, document details about your water source: depth of your well, its construction, and when your water was last tested for radon. Include any past water quality reports, and note any unusual odors, tastes, or stains that concern you. This information is crucial for professionals or for choosing the right approach to address radon in your water supply.

2. Assessing Treatment Capacity Relative to Your Daily Water Use

Radon treatment equipment needs to handle your household's typical daily water consumption. Estimate your daily water use considering all activities using water—cooking, cleaning, bathing, and outdoor uses. This helps ensure any filtration system you consider, such as the Fleck Radon in Water Filter, can process enough water without reducing flow or adding inconvenience.

3. Understanding Certified Laboratory Test Reports for Radon in Water

A certified laboratory test is essential to determine your water's radon concentration. These tests measure radon in picocuries per liter, quantifying the radioactivity from radon gas dissolved in water. Test reports typically provide the measured level and compare it against federal benchmarks. Although no federal limits were exceeded in the Greene County samples cited, your home's water test will show your actual water concentration.

4. Seasonal and Multi-Year Variation in Radon Levels

The Greene County groundwater radon measurements span two days in June 2025, showing a range from 200 to 450 pCi/L. Radon levels can vary with changes in groundwater conditions, temperature, and water table fluctuations throughout seasons and over years. Understanding this variation highlights the need for periodic testing rather than relying on a single measurement to estimate radon exposure accurately.

5. Consequences of Leaving Radon Untreated in Household Water

Radon in drinking water can release radon gas into indoor air during water use, contributing to overall radon exposure. Long-term exposure to elevated radon gas is associated with lung health risks. Addressing radon in water reduces this indoor air source. However, untreated water radon does not typically cause immediate symptoms. It is a concern primarily for cumulative impact over years.

6. How Radon Enters Groundwater in Greene County

Radon forms naturally from the decay of uranium present in soil and rock. In Greene County's aquifer, radon-222 dissolves into groundwater as it percolates through the earth's geologic materials. Wells drawing from this aquifer may bring radon into household water, making it important to understand local geology and water source characteristics when assessing radon potential.

Closing Step: Ordering the Definitive Radon Test for Your Water

The single test you should order is a certified radon-in-water analysis from a state or nationally approved laboratory. This test will provide your household water radon concentration in picocuries per liter, settling the question of whether treatment is necessary. If levels are of concern, the Fleck Radon in Water Filter ships ready to configure as a documented solution to reduce radon in residential water supplies.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2025-06-11. 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 Radon-222 in the aquifer (Greene County): 3 results from 3 wells, median 290.0 pCi/L, range 200.0-450.0 pCi/L; none above any federal threshold
