Understanding how radon in water affects your household begins with careful consideration of regional data and your own water source. Government measurements from the U.S. Geological Survey show that radon-222 was detected in six wells sampled in the Broward County aquifer at depths between 96 and 140 feet during mid-2016. The median radon concentration found was 415 pCi/L, within a range from 210 to 870 pCi/L. These figures reflect what was found in the area’s aquifer wells, not the radon level in your specific well or tap water. Testing your household water is necessary to know your own water’s radon concentration.
How Sample Depth, Well Depth, or Source Type Affects Expectations
Sample Depth Varies Radon Detection
Radon concentrations differ by depth; the sampled wells in Broward County were between 96 and 140 feet deep, reflecting conditions typical for that aquifer zone.
Well Depth Influences Radon Presence
Household wells drawing from similar depths may encounter radon levels comparable to those recorded, but shallower or deeper wells can differ significantly.
Source Type Matters
Water from private wells draws directly from groundwater, whereas municipal water systems may blend multiple sources, affecting radon concentrations.
What Happens When Radon Remains Untreated Over Years
Chronic Exposure to Radon in Water
Radon in water can release into indoor air during household use. Over time, prolonged exposure may contribute to health risks, though the extent depends on radon concentration and ventilation.
No Immediate Taste or Smell Changes
Radon does not affect water taste, odor, or appearance; therefore, its presence often goes unnoticed without testing.
Radon Decay Produces Radioactive Particles
These particles can pose inhalation risks when water is aerosolized, such as during showering or cooking.
How Water After Treatment Differs at the Tap
Reduction of Radon Levels
Using filtration technology such as the Autotrol Radon in Water Filter reduces radon concentrations in water, improving water quality at the point of use.
No Change to Water’s Physical Properties
After filtration, water retains its original taste, clarity, and odor, with radon levels appreciably lowered.
Ongoing Performance Requires System Use
The filtration system ships ready to configure for household water treatment, maintaining effective radon reduction when operated properly.
Household Signs That May or May Not Suggest Radon Presence
Signs Not Showing Radon Presence
- Discoloration or staining of fixtures
- Unpleasant tastes or odors
- Visible sediment or cloudiness
Signs Possibly Related to Radon
- Elevated radon found by water testing
- Family health concerns related to long-term radon exposure
- Known presence of radon gas in the indoor air
What to Record Before Seeking Radon Treatment Advice
Gather Recent Water Test Results
Record your water radon levels established by certified laboratory testing specific to your household source.
Note Well Details
Write down your well depth and construction details that affect water source characteristics.
Document Plumbing System Features
Include the age, materials, and layout of your household plumbing to assess possible impact on water quality.
The Influence of Plumbing Material and Age Independent of Source Water
Older Plumbing Can Affect Water Quality
Metal pipes may contribute taste or color changes unrelated to radon content, necessitating separate evaluation.
Plastic or Newer Materials May Reduce Secondary Effects
Non-metal plumbing often minimally influences water chemistry, focusing concern more squarely on source water radon.
Plumbing Does Not Generate Radon
Radon is a naturally occurring radioactive gas originating in groundwater, unaffected by plumbing materials or system age.
Measurements from the Broward County aquifer reflect radon concentrations found in six wells sampled between 96 and 140 feet deep during 2016. These data represent area conditions and do not substitute for testing your own household water. Visit the U.S. Geological Survey site for detailed sample records of the Broward County aquifer radon levels.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-01. 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 (Broward County): 6 results from 6 wells, median 415.0 pCi/L, range 210.0-870.0 pCi/L; none above any federal threshold
