Saratoga County, NY: EPA's radon zone, explained

EPA places Saratoga 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. That puts Saratoga County in the 63rd percentile nationally for radon potential — higher than 63% of the counties EPA has rated.

Where Saratoga County sits nationally

Saratoga County, New York is home to about 240,360 people across 809.97 square miles. Averaged across its land area, Saratoga County runs about 297 people per square mile. By population, Saratoga County is the 99th largest of every county sharing its EPA zone — the 90th percentile by population within that zone. EPA's geology-based Region 2 groups Saratoga County with 82 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Saratoga County's Zone 2 prediction lands in the gap between the two. Saratoga County's Zone 2 rating sits in the middle nationally; EPA's guidance is unchanged by that — test every home regardless of its zone.

Next steps for a home in Saratoga County

For a Saratoga County homeowner, the order is simple: test first, since a kit costs a small fraction of what mitigation would. Only if the result clears 4 pCi/L does a system — typically $800–$2,500, about $1,200 for a common install — become worth pricing out.
