Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Ward 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.

Ward County, Compared

Ward County radon figures, compared

Calculated by Radon411

No CDC figure names Ward County, in any year or ten-year total; over the 2007 to 2016 laboratory totals, the agency's counts reach 140 Texas counties without 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 Midland County (68 miles away) at 1.0%, Lubbock County (163 miles away) at 57.8% and El Paso County (185 miles away) at 0.0%. 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 Ward County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 94% of the county's land low radon potential.

The ground under Ward County

Predicted

Most of the ground under Ward County is one class on USGS's geologic map: 94.5% of its land is low radon potential, with 5.5% moderate. The map puts 94.5% of Ward County in the area it calls Southern High Plains and Plateaus and 5.5% in Western Mountains and Basins. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).

Ward County, Cities and towns

Cities and towns in Ward County

About 11,125 people live in Ward County by the Census Bureau's estimate for July 1, 2025, 554 fewer than in 2020 (−4.7%). That works out to 13 people per square mile of land. Monahans, the largest place on its list (7,427 residents in all), extends beyond Ward County, so no share of the total is worked out for it. CDC publishes no radon test count for Ward County; across Texas its counts for 2007 to 2016 come to 0.1 tests for every 1,000 residents (2025 estimate).

From Monahans to Pyote, CDC publishes no figure by town: each reads Ward County's.
