While herbicide exposure can occur anywhere, Corona-area routines often create recognizable patterns:
- Residential and HOA landscaping: Seasonal weed control for driveways, common areas, and slope landscaping—sometimes with limited notice to residents.
- Front-yard and backyard application: Homeowners or hired crews applying weed killer around patios, fences, and walkways where family members play.
- Work around grounds and industrial sites: Facility maintenance, landscaping contractors, warehouse-adjacent groundskeeping, and outdoor cleaning where herbicides may be applied near pedestrian routes.
- Secondhand exposure at home: Work boots, gloves, uniforms, and equipment stored in garages or laundry areas—residue can follow people indoors.
These situations matter legally because the strongest cases are built on specific exposure circumstances, not general concerns.
