Many cases we see for glyphosate exposure don’t start with “I used Roundup.” They start with a life event—an oncology appointment, a biopsy result, or a specialist’s discussion of risk factors—followed by a careful look back at years of exposure.
In Palo Alto and nearby areas, common pathways include:
- Residential landscaping and garden care (including spot-spraying weeds near patios, driveways, and walkways)
- Community and HOA-maintained grounds where herbicides may be applied seasonally
- Employment involving groundskeeping, parks, or property maintenance, including contractors who work across multiple sites
- Secondhand exposure from residue carried on work clothing, shoes, or equipment stored in garages or sheds
When the timing is unclear, that’s where documentation and a structured review can make a difference.
