Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Waynesboro city 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.

Calculated by Radon411

In Waynesboro city, about 5 in 10 reported tests over the 2008 to 2017 laboratory totals (95 of 196) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 12.8 points higher. Across 131 Virginia counties pooled together, 30.4% of tests reached that level, so Waynesboro city runs 18.1 points above its state.

Augusta County, the one bordering county with a figure for the same period, reported 50.1%. By share, Waynesboro city is 14th of 84 Virginia counties with 30 or more tests for the same period.

Half the tests came in under 3.8 pCi/L and half over it; the single highest reached 28.3 pCi/L. Below the action level, 50 tests (25.5%) came in under 2 pCi/L, against 44.7% statewide, and 51 tests (26.0%) fell between 2 and 4, against 24.9% statewide.

Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 48.5% share point the same way here. USGS geology rates 91% of the county's land high radon potential. CDC also counts 17 tests taken after mitigation in Waynesboro city for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Waynesboro city went from 170 tests (2005 to 2014) to 196 (2008 to 2017), the share going from 49.4% to 48.5%.
