Many Concord residents aren’t exposed at a single, memorable moment—they’re exposed through repeat routines that look “normal” day to day.
Common patterns we see include:
- Home and HOA landscaping: weed control for driveways, fences, and common-area edges around residential complexes.
- Street-adjacent yards and commute corridors: application near property lines, medians, and landscaping strips along routes people drive and walk every day.
- Work tied to grounds maintenance: landscapers, groundskeepers, and maintenance staff who handle weed control as part of keeping properties presentable.
- Seasonal property care: late spring and summer applications that coincide with when people notice symptoms starting to change.
If you’re trying to connect illness to exposure, the challenge is often not whether you used or saw herbicides—it’s proving when, what product/ingredient, and how exposure occurred.
