Radon in Guadalupe County, New Mexico
Last updated
Guadalupe County is one of 26 New Mexico counties (out of 33) that EPA places in Zone 2. 7 ZIP codes reach into the county, 3 of them entirely.
What the zone means for a Guadalupe County home
Zone 2 means EPA predicted a county-wide average between 2 and 4 pCi/L. That is below EPA's action level on average, but plenty of individual Guadalupe County homes will be above 4 pCi/L, and EPA suggests considering a fix between 2 and 4 pCi/L too.
A short-term test kit costs little and takes two to seven days. If your result is 4 pCi/L or higher, EPA recommends a follow-up test and, if it is confirmed, a mitigation system, which typically uses a pipe and fan to pull soil gas from under the foundation and vent it above the roof. Check a result with the level calculator and plan your next step with the follow-up planner.
