In and around Cambridge, weed killer exposure often comes through routines that don’t feel like “industrial” risk:
- Homeowners or family members treating driveways, garden beds, and yard edges
- Seasonal landscape and lawn services working on neighboring properties
- Farm-adjacent and agricultural maintenance tasks where herbicides are used on a schedule
- Property cleanups after storms or growth, when products may be reapplied without full labeling kept
Because exposure can occur quietly over time, many people only connect the dots after a diagnosis. That delay makes documentation especially important—product labels get thrown away, receipts disappear, and the timeline becomes fuzzy.
