## Radon Mitigation Questions in Osceola Homes

The local problem

### Air or water? Sorting out the radon source in Osceola homes

**What you notice:** A rural home tests high, and the owner is not sure whether the radon is coming from the soil or the well.

**Why it happens here:** In-town Osceola homes draw water from West Lake, a surface source, while many rural Clarke County homes rely on private wells where groundwater can carry radon.

**How we fix it:** We pair air radon testing with a well water test, then install a sub-slab system, a waterborne system or both.

### Every Iowa county is EPA Zone 1

About 71% of Iowa homes test above the EPA action level of 4.0 pCi/L. Your neighbor's number tells you little about yours, so a 48-hour test is the only way to know.

### Winter makes it worse

When the furnace runs and the ground freezes, warm air rises out of the house and pulls soil gas in through the slab, sump and cracks.

### High results stall closings

A failed radon test during inspection can hold up a sale. We test inside your contingency window and can install and verify a system before closing.

Local homes

### In-Town and Rural Homes

In-town homes use city water from West Lake, so radon there almost always comes from the soil. Older basements usually need a standard sub-slab system with sealing.

Rural homes may have crawlspaces or private wells. We test the water as well as the air and design sub-slab, crawlspace and waterborne systems to match.
