In the Portland metro area—including Tigard—people are frequently exposed in more than one way:
- Residential spraying and lawn care (including repeated applications over seasons)
- HOA, property management, or shared landscaping decisions near homes and townhomes
- Secondary exposure from tracked residue or nearby treated areas
- Work-related exposure for maintenance, landscaping, groundskeeping, and retail/warehouse staff who handle chemicals
Because exposure may be spread across homes, jobs, and common areas, your case often depends on building a credible timeline—not just naming a product.
