In suburban Contra Costa County communities like Clayton, exposure can happen in ways that don’t feel “industrial”:
- Backyard and driveway weed control after mowing or landscaping
- Neighborhood application that drifts onto lawns and shared outdoor spaces
- Take-home exposure from family members who use products for work or maintenance
- Seasonal routines (spring cleanup, summer weed control) that blur dates later
When medical symptoms surface months or years afterward, it becomes harder to remember product names, application frequency, and where residue may have collected. That’s why residents often benefit from a structured intake right away—so nothing critical gets lost.
