Is radon high in Chenango County, New York?

Moderate. The model predicts a long-term basement average of 2.4 pCi/L in Chenango County (about 1.3× the US average of 1.8 and about 1.8× the New York average of 1.4). That is in the 2-4 pCi/L range where the EPA recommends considering mitigation. Ranked 8 of 62 New York counties.

Should I test for radon in Chenango County?

Yes, soon. With a predicted average of 2.4 pCi/L, many homes in Chenango County will test above the 4 pCi/L action level. Use a short-term kit first; if it reads 2 or higher, confirm with a long-term test or continuous monitor before deciding on mitigation.

What does EPA Radon Zone 1 mean for Chenango County?

Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and classifies whole counties. The newer model's predicted average of 2.4 pCi/L does not line up with Zone 1, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.

How much does radon mitigation cost in Chenango County?

A standard active sub-slab depressurization system typically runs $800-$2,500 installed nationally; New York quotes vary with foundation type (slab, crawlspace, basement), home size and local labor.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Chenango

The typical Chenango County home is predicted in the 2-4 pCi/L band. The EPA's guidance for this range is to consider fixing, because there is no known safe level and roughly one home in several in a moderate area will test above 4.

Note that the EPA classifies Chenango County as Zone 1 while the newer model predicts 2.4 pCi/L. The zone map predates two decades of test data; where they disagree, we grade on the model but show both. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.

Comparable New York counties: Schoharie County (2.4), Chemung County (2.5), Delaware County (2.5), Allegany County (2.4). The state's highest is Schuyler County at 2.8 pCi/L.
