Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Goochland County in and predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county. That is one forecast for the whole county, not a reading of any address in it; homes above EPA's turn up in all three zones.

Goochland County radon figures, compared

Calculated by Radon411

In Goochland County, about 3 in 10 reported tests over the 2008 to 2017 laboratory totals (35 of 114) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 5.0 points lower. Across 131 Virginia counties pooled together, 30.4% of tests reached that level, so Goochland County runs 0.3 points above its state.

Of 6 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 5 a smaller one; the spread is 23.0% (Hanover County) to 38.1% (Louisa County). By share, Goochland County is 51st of 84 Virginia counties with 30 or more tests for the same period.

Half the tests came in under 2.4 pCi/L and half over it; the single highest reached 118.9 pCi/L. Below the action level, 49 tests (43.0%) came in under 2 pCi/L, against 44.7% statewide, and 30 tests (26.3%) fell between 2 and 4, against 24.9% statewide.

Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 30.7% share point the same way here. USGS geology rates 90% of the county's land high radon potential. CDC also counts 8 tests taken after mitigation in Goochland County for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Goochland County went from 104 tests (2005 to 2014) to 114 (2008 to 2017), the share going from 31.7% to 30.7%.

The ground under Goochland County

Predicted

Most of the ground under Goochland County is one class on USGS's geologic map: 89.9% of its land is high radon potential, with 10.1% moderate. The map puts 53.4% of Goochland County in the area it calls Goochland Terrane and 36.4% in Inner Piedmont, with one smaller area beside them. USGS gives the first a radon index of 13 and the second 12, both in the high band (12 to 17).
