EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Foard County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Foard County, Compared

Foard County radon figures, compared

Calculated by Radon411

CDC's county radon counts over the 2007 to 2016 laboratory totals cover 140 Texas counties, and Foard County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.

The nearest counties with a figure are Lubbock County (120 miles away) at 57.8%, Randall County (139 miles away) at 71.4% and Potter County (156 miles away) at 20.0%. Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%).

EPA's 1993 map puts Foard County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Foard County, Geology

The ground under Foard County

Predicted

USGS's geologic map puts all of Foard County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas, to which USGS gives a radon index of 7, in the low band (5 to 8).
