The ground under Bartow County

Predicted

Most of the ground under Bartow County is one class on USGS's geologic map: 79.6% of its land is low radon potential, with 20.4% moderate. The map puts 79.6% of Bartow County in the area it calls Rome-Kingston Thrust Stack and 19.1% in Georgiabama Thrust Stack (North), with one smaller area beside them. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
