In the Tacoma area, exposure stories commonly involve:
- Residential property treatments (driveways, fences, yards, and community landscaping)
- Worksite or jobsite exposure tied to groundskeeping, landscaping, maintenance, or environmental services
- Secondary exposure—for example, family members exposed through shared living spaces or time spent near treated areas
- Seasonal application timing that doesn’t match when symptoms appear
That mismatch is one of the toughest parts of these claims. Washington injury cases depend on evidence that can explain the timeline clearly—what happened, when it happened, and how it connects to diagnoses later.
