Debris Analysis
- 392,161 acres burned
- 14% of county
- 23 days to contain
- 2,668 buildings destroyed
- 165 buildings damages
- 2,929 accessory buildings destroyed
- Estimated over 50% homeowners uninsured or underinsured
- County concerned with hazards at burned homes and wants to conduct private
property cleanups
- Concerns with chemicals contaminating nearby drinking water sources
Funding for Private Part Cleanups
- FEMA generally does not fund private property cleanups by other than
homeowner
- FEMA requested County to verify concerns by testing burn ash
- FEMA would fund the testing
- County hired GeoSyntec to conduct the testing
- County and State experts worked with GeoSyntec to develop a Scope of Work
Scope of Work
- Entire fire area is “site”
- Sampling data evaluate presence of contaminates that present hazards to humans
and environment
- Developed Sampling Plan
- Document physical hazards
- Analyze samples
- Final report
Sampling Plan
- Two samples from 50 home sites
- One from house pad, near kitchen or bathroom
- One from other location with highest potential of contamination (garage, shed)
- Test for metals, pesticides, herbicides, asbestos, polychlorinated biphenyls
Findings of Debris Analysis
- 86% of samples contained hazardous substance constituents
- Debris contained constituents at concentrations that pose threats to
drinking water bodies
- Physical hazards found at 76% of sites
- "Residual debris should be removed with caution and properly disposed
as soon as possible to reduce the possibility of human contact with these
constituents and adverse impacts to human health and the environment"
