Venice, Geology
The ground under Venice
PredictedUSGS's geologic map puts all of Venice's mapped land in one class: low radon potential. All of it lies in the area the map calls Gulf/Atlantic Lowland and Central Highland, to which USGS gives a radon index of 6, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Gulf/Atlantic Lowland and Central Highland | sand, silt, clay, gravel | Low | 6 | 100% |

Venice beside its county and Florida
Neither Venice nor Sarasota County as a whole has any land USGS rates above low potential. Across Florida 7.1% of the land is rated moderate; none of Venice's is.

Venice, Questions
Questions about radon in Venice
What radon zone is Venice in?
Venice takes its zone from Sarasota County, which EPA puts in Zone 3, the map's lowest class: a predicted county average under 2 pCi/L. A low zone does not clear a house: homes over the action level are found in all three.
What are radon levels in Venice?
Sarasota County's 496 tests for 2023 put 12.3% at or above 4 pCi/L: most tests near Venice come back under EPA's action level, but not all. The median reported result was 1.6 pCi/L.
Should I test my home in Venice?
Yes. Roughly one reported test in 8 in Sarasota County reached 4 pCi/L. That is below Florida's pooled 18.5%, and still not a reason to skip it, and ranks Sarasota County 10th of the 30 Florida counties with 30 or more tests. Only a test puts a number on one house. How to test a home.
What ground is Venice built on, as far as radon goes?
USGS's geologic map puts all of Venice on one named area, "Gulf/Atlantic Lowland and Central Highland", rated low for radon potential, radon index 6.
Is radon higher in the counties around Venice?
Some are and some are not. Against Sarasota County's 12.3%, 3 of the 8 nearest counties with a figure report more and 5 less, from Pasco County (0.6%, 82 miles off) to Charlotte County (31.9%, 34 miles off).
The answers use the published figures of Sarasota County, the county Venice lies in.
