Every case is different, but Lafayette residents commonly describe exposure histories that follow local routines:
- Lawn and landscaping care: regular home use of weed killers, lawn treatments, or weed control performed by contractors.
- Property maintenance near homes and trails: exposure to freshly treated areas—follow-up mowing, cleanup, or contact with residue on tools and outdoor gear.
- Worksite exposure: jobs involving groundskeeping, facility maintenance, agriculture, or construction-adjacent landscaping where herbicides may be applied seasonally.
- Secondhand contact: residue carried indoors on work boots, gloves, clothing, or vehicles used for treatment and maintenance.
In Lafayette, these scenarios matter because they can affect when exposure likely occurred and how it aligns with a later diagnosis.
