In Iowa City, many properties change hands frequently—new leases, landscaping refreshes, and seasonal weed control. That means exposure details can disappear fast:
- Sprayed lawns, sidewalk edges, and driveways near where people walk daily
- Landscaping contractors who apply weed control between tenants
- Shared outdoor spaces (apartment courtyards, townhouse common areas, rental “maintenance”)
If your diagnosis came years after exposure, that’s normal—but it makes early documentation critical. The sooner you preserve records, the easier it is to connect the dots.
