The King’ Mt Link is a geological formation that runs from approx. Clover SC to Iron Station NC.
*These counties EPA’s classifies as a Zone 2, but do not reflect true field conditions.
Cleveland – Shelby north, especially Moss Lake Gaston – Gastonia south to state line Lincoln – Lincolnton east to Lake Norman Mecklenburg – south side of Charlotte to state line York (SC) – Rock Hill north to state line, is a zone 2 but my highest reading 164 pCi/L
** EPA’s Map and zones are based on data that is over twenty years old.
Radon levels vary from house to house. The only way to know is to test.
