Radon & arsenic · Full list

Every ZIP code where both are elevated

Name: Combined exposure: modeled indoor radon and modeled groundwater arsenic, by ZIP code

Two exposures that come from the same rock and soil, and every US ZIP code where a modeled reading of each runs high at the same time. Ordered by whichever of the two ranks lower nationally. Select any row to open that ZIP code’s own health page.

Where they are

Iowa — 202
Minnesota — 154
Ohio — 64
11 other states — 64

Three states hold the large majority of this list. That concentration is the finding, not a caveat: radon and arsenic both come from the rock a community sits on, so where both run high together follows specific bedrock and does not exist in most of the country. It is also the honest reading of our coverage — groundwater arsenic can only be modeled for about three quarters of US ZIP codes, so a national list of “the worst” would quietly claim we had checked places we had not.

Showing all 484 of them. Every ZIP code here also appears on its own state page and on its own health page.

Not on this list does not mean safe. Groundwater arsenic cannot be modeled for every ZIP code in the country, and a ZIP with no modeled value for either exposure is absent from this list because it was not measured — never because it was checked and found clear. A ZIP that was measured and simply does not carry both exposures is not listed either. Absence from this page is never a statement that a place is safe.

How a ZIP code gets on this list

Modeled, not measured. Indoor radon uses the Li national ZCTA-level model; groundwater arsenic uses the USGS private-well probability model. Neither is a reading from your home or tap. A ZIP with an unobservable leg is shown as not measured, never as "not impacted." The two references are federal and different: radon's 4 pCi/L is an action level (a recommendation to act), arsenic's 10 µg/L is the maximum contaminant limit EPA sets for public water systems, and private wells are outside it. A ZIP reaches the list by ranking in the highest 10% of US ZIP codes for each exposure. The list is national; each state also has its own page with that state's full set.

Indoor radon comes from the Li national ZCTA-level model; groundwater arsenic from the USGS private-well probability model. Both are modeled, never a reading from a home or a tap — the CSV header names each source and its terms.
