In Signal Hill, many people are exposed through normal residential life—yard maintenance, neighborhood landscaping, pest control services, and nearby application around commercial or industrial corridors. Commuting patterns can also matter: if you spent long hours near areas where vegetation was treated, or if a family member worked in a role involving herbicides, your exposure timeline may be different than you expected.
Because these situations are common, documentation can be scattered. A key early step is reconstructing:
- Where application likely occurred (home, rental property, workplace, nearby areas)
- When it likely happened (seasonal patterns, job schedules, property records)
- What products were used (labels, photos, receipts, service records)
