Many Northbrook residents assume herbicide exposure only occurs when they personally apply a product. In practice, exposure can come from:
- Landscaping and grounds crews working on nearby homes, HOAs, or commercial properties
- Routine turf management at parks and community areas
- Secondhand contact (tools, gloves, work boots, or clothing carried from a job)
- Seasonal lawn schedules that lead to repeated applications over years
In these situations, it’s common for people to remember when they noticed odors, spray patterns, or freshly treated areas—yet struggle to identify exact product names or application dates. Northbrook claims often hinge on reconstructing that timeline using whatever documentation remains.
