Government sampling of groundwater in Pasco County's aquifer 120FLRD found radon-222 detected in every tested well, with a median concentration of 3010 picocuries per liter (pCi/L) based on four samples collected from wells 33 to 53 feet deep. No sample exceeded federal limits. These figures apply to wells sampled in this region, not to any individual household supply.

Fixtures, Appliances, or Processes Affected First

Showering and Bathing

Radon readily transfers from water to air when water is agitated, making showers and baths key exposure points.

Cooking

Boiling or simmering water releases radon gas, increasing indoor air levels during meal preparation.

Dishwashing

Water heated in dishwashers also emits radon gas, though exposure is generally lower than showers.

Drinking Water

Ingested radon passes quickly through the body, but inhalation of radon gas released from water presents a greater health consideration.

Additional Questions for Commercial or Industrial Operators

What is the volume of water used daily?

Higher water demand may require larger treatment capacity to manage radon effectively.

Does the operation involve water heating or agitation on a large scale?

Processes that generate aerosols or steam can increase radon release into air.

Are there regulatory requirements specific to commercial exposure?

Industry standards or occupational safety guidelines may apply beyond residential considerations.

Is continuous monitoring of radon in water or air implemented?

Regular testing helps assess radon fluctuations linked to operational changes.

Distinguishing Radon From Similar Water Issues

Radon vs. Other Radioactive Elements

Radon is a gas formed by decay of radium but behaves differently in water than solid radioactive minerals.

Radon vs. Taste or Odor Complaints

Radon is odorless and tasteless; other substances cause sensory issues without radioactive properties.

Radon vs. Aesthetic Secondary Standards

Standards for taste or staining are unrelated to radon levels and should not be confused.

Plumbing Material and Age Effects

Material Does Not Affect Radon Levels in Water

Radon concentrations originate from water source, not pipe composition.

Older Systems May Promote Air Exchange

Leaks or loose fittings can influence radon gas movement inside a home but do not change water content.

Water Heater Type and Temperature Influence Radon Release

Hot water systems can enhance radon emission into indoor air during usage.

Judging Treatment Capacity for Household Demand

Estimate Average Daily Water Use

Typical household consumption guides sizing for radon reduction equipment.

Consider Peak Usage Periods

Capacity should accommodate times of increased water flow to maintain effectiveness.

Match System Capability With Radon Levels

Higher detected radon in the area suggests the need for equipment sized to handle elevated concentrations.

Evaluating radon in household water involves understanding local sampling data and its implications for water use and indoor air quality. Testing your own water is essential to determine specific concentrations. The Autotrol Radon in Water Filter ships ready to configure and offers treatment scaled to household demand, addressing radon removal effectively when matched properly.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-11-19. 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 120FLRD aquifer (Pasco County): 4 results from 4 wells, median 3010.0 pCi/L, range 1300.0-9000.0 pCi/L; none above any federal threshold
