San Mateo is a Peninsula community with a mix of suburban homes, shared landscaping, and nearby commercial/industrial activity. That environment can create exposure pathways that are easy to miss at first, such as:
- Home and HOA landscaping: treatments performed on schedules that don’t always match what homeowners notice.
- Secondary exposure: residue tracked indoors or onto patios after applications.
- Work-related contact: jobs that involve maintenance, groundskeeping, or outdoor work near treated areas.
- Timing gaps: symptoms and diagnoses that may appear months or years after exposure.
When you’re dealing with a possible weed killer injury, these patterns matter because claims often turn on what you can prove about exposure and when it happened.
