In suburban communities like Franklin, exposure often comes from how properties are maintained:
- Homeowners and renters using herbicides for yards, driveways, and landscaping
- Contractors and lawn service workers applying weed killer as part of regular work
- Nearby application drift affecting neighboring homes, sidewalks, or shared outdoor areas
- Seasonal maintenance routines that make it easier to remember “when it started,” even if the exact product is lost
Because these situations can be tied to routine schedules—spring cleanup, summer growth control, fall edging—many Franklin residents first realize something is wrong only after symptoms develop or a diagnosis arrives.
