Arvada’s mix of established neighborhoods, homeowners’ associations, and routine yard/grounds maintenance can create exposure paths that aren’t obvious at first. People often remember:
- seasonal applications on nearby properties
- driveway and curbside weed control after snowmelt or during dry spells
- landscaper or maintenance work that happened while they were commuting or at work
- product containers that were discarded once the job was done
When exposure is hard to pinpoint, the key becomes building a credible timeline from whatever you can still access—without guessing.
