What this actually means for a house in Ford County

Fixing a home becomes an EPA recommendation past 4 pCi/L, and that is precisely the side of the line Ford County's Zone 1 prediction lands on, well above the roughly 1.3 pCi/L most US homes average. A Zone 1 rating means testing is worth doing sooner rather than later, but it is still county-wide average, not a reading for any single house — some homes in Ford County will test well under the action level, and EPA's guidance is to test regardless of zone.

Next steps for a home in Ford County
