In Westchester County, it’s common for people to be exposed through:
- Seasonal lawn and driveway treatments (spring/fall application windows)
- Landscaper or maintenance work at home or in nearby properties
- Indoor impacts from tracked-in residues (shoes, work pants, children’s outdoor play)
- Multiple product use over the years (weed killer plus fertilizers and other yard chemicals)
When symptoms appear—sometimes months later, sometimes years later—the connection can become harder to prove unless the early details are captured.
