In Mill Valley, toxic exposure cases often center on situations residents commonly encounter:
- Construction, remodeling, and demolition dust: drywall work, sanding, insulation removal, and old materials may release hazardous particulates.
- Mold and moisture problems in older homes: hidden water intrusion can lead to recurring remediation disputes and inconsistent testing.
- Ventilation and indoor air failures: HVAC breakdowns, clogged filters, or improper duct cleaning can create a “why are we all getting sick?” pattern.
- Seasonal landscaping and pesticide drift: chemical application near homes, schools, or shared outdoor spaces can trigger symptoms—especially for asthma or respiratory issues.
- Tourism-driven events and temporary facilities: temporary kitchens, event structures, or cleaning chemicals can create exposure routes that get overlooked.
In these scenarios, what matters is not only what you think caused the problem—it’s when symptoms began, how they changed after the event, and what the property/workplace records show about conditions at that time.
