In and around North Liberty, many people don’t think of themselves as “industrial chemical workers.” Instead, they’re exposed through ordinary routines:
- Lawn care and garden weed control at home
- Landscaping for new construction and property maintenance
- Spraying near sidewalks, trails, or common areas where foot traffic is constant
- Shared equipment or take-home residue from someone who does yard work for others
Because these exposures are often part of regular life, people sometimes hold onto fewer product records than they expect. That’s why early documentation can matter—before bottles disappear, receipts get thrown away, and memories of the exact timing blur.
