In suburban and residential communities like La Puente, exposure evidence commonly gets fragmented over time. People may remember the product being used on a driveway, in a backyard, or near a walkway—but not where the container is stored, what the label said, or the exact application dates.
It’s also common for exposure to involve more than one setting:
- Home use (gardens, landscaping, patios)
- Work exposure (maintenance, landscaping, groundskeeping)
- Environmental contact (neighbors’ applications, shared property edges)
When the timeline is fuzzy, the case often hinges on assembling a believable record from what’s still available—medical documentation, employment records, purchase history if any, and witness or neighbor recollections.
