Meade County, SD radon potential

EPA places Meade County in Zone 2 - Moderate Potential — a predicted county-wide average indoor radon level between 2 and 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Nationally that's the 51st percentile for radon potential — Meade County outranks 51% of every county EPA has rated.

EPA's geology-based Region 8 groups Meade County with 290 other counties nationally sharing its underlying rock and soil profile.

Zone vs. an actual test

Call it a middle case: above the 1.3 pCi/L most US homes average, below the 4 pCi/L line EPA uses to recommend mitigation — that's Meade County's Zone 2 prediction. A county-wide moderate average, like Meade County's, can still hide a specific house well above or below it — testing is what actually answers the question.

Testing and mitigation in Meade County

A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
