In a residential community like San Gabriel—where many people live near landscaped areas, schools, parks, and multi-unit properties—exposure often comes from day-to-day contact rather than a dramatic “incident.” Common patterns include:
- Lawn and garden treatment at homes, townhomes, and nearby properties (including repeated seasonal applications).
- Landscaping and maintenance work for contractors, property staff, and caretakers who handle herbicides as part of routine upkeep.
- Shared outdoor spaces in apartments and community settings, where applications can affect multiple households.
- Secondary exposure—for example, residue tracked indoors or handled on work clothing before washing.
- Neighborhood proximity to application areas, especially when treatments happen close to sidewalks, driveways, or common walkways.
When exposure isn’t tied to one clear event, the case turns on reconstructing a credible timeline from whatever evidence still exists.
