In and around Barstow, exposures can happen in ways people don’t always recognize at the time:
- Outdoor maintenance work (groundskeeping, landscaping, facility upkeep, and job sites where vegetation is controlled)
- Property and neighborhood weed control, including repeat applications during dry seasons when vegetation management becomes routine
- Secondhand exposure, such as residue carried on work clothing, equipment, or vehicles used to transport supplies
- Mowing or clearing after spraying, where contact occurs during cleanup rather than during the original application
When illness develops later, the challenge is proving what happened, when it happened, and how it connects to the condition your doctors identified.
