In Corte Madera, exposure claims frequently involve environments where herbicides are used or where residue can spread:
- Home and HOA landscaping: Spraying or application around property edges, walkways, and common areas.
- Secondhand exposure: Mowing, trimming, or cleaning up after treatment—especially when residue remains on clothing, gloves, or equipment.
- Local contractors and groundskeeping: People who work for landscaping companies, facilities, or property maintenance may encounter treated areas repeatedly.
- Proximity to treated vegetation: Even when you didn’t apply the product yourself, frequent contact with treated brush/edges (for example, during maintenance or outdoor routines) can be relevant.
Because the facts matter, the first step is usually reconstructing how exposure likely occurred—then matching that history to your diagnosis.
