SMOKE IMPACT ASSESSMENT report
Embedded Files
My house is close to Altadena California which suffered a wildfire a few months back. 1000 structures were burnt to the ground. Since my house is close I had an in-depth analysis done on chemical residues and toxins in and about my house including the attic living spaces, Garage and all outdoor areas including a lawn and garden. I would like to have an AI LLM review the report and explain it to me in a simple format including graphs and schedules that I can understand and share with others. Please provide a comprehensive prompt that will generate the response desired
You are an AI language model specialized in interpreting and simplifying complex scientific reports. I have a comprehensive report detailing the results of an in-depth analysis of chemical residues and toxins found in and around my house, which is located near Altadena, California, an area affected by recent wildfires.

By following this structure, please provide a comprehensive yet understandable breakdown of the report findings that I can easily share with others.
Okay, the user has shared multiple documents related to a wildfire impact assessment for a property in Pasadena, CA. They want me to simplify the complex scientific report into understandable language with visual aids.
First, I notice there are three files: two Chain of Custody forms and one detailed 38-page assessment report from Safeguard EnviroGroup. The main report contains extensive technical data about wildfire residue analysis. The user lives near Altadena, which was affected by the January 2025 Eaton Fire that burned 14,000 acres about 3,000 feet from their home.
The report includes several types of sampling: combustion particle analysis (soot/char/ash), heavy metal testing, VOC air sampling, and visual assessments. I need to extract the key findings while avoiding jargon. For example, T-03 (exterior breaker box) and T-04 (family room windowsill) showed "atypical" combustion particles (4-9%), which indicates wildfire impact.
For health implications, I should emphasize that:
- Elevated soot/char (4%+) may cause respiratory irritation
- Lead dust in Family Room (2.4 µg/100cm²) exceeds new EPA action levels
- VOC levels were mostly low except 2-Furaldehyde in dining room
The visual aids will help make data digestible. I can create:
- Bar chart for combustion particles showing "typical" vs "atypical" samples
- Table summarizing heavy metal results with color-coded risk levels
- Timeline showing remediation priority phases
I notice the user seems concerned about family safety - they specifically mention "toxins in my house." While the report notes no immediate danger, I should highlight precautionary steps like avoiding dusty areas and using HEPA vacuums. The recommendations section already provides detailed cleaning protocols, which I can condense into a simple checklist.
The disclaimer about limitations is important too - this assessment only covers sampled areas. I'll mention that some contaminants like asbestos weren't tested.
For presentation, I'll structure it as: Introduction → Key Findings → Health Implications → Visual Data → Recommendations. Keeping language simple but precise - instead of "polycyclic aromatic hydrocarbons," I'll say "combustion chemicals that may stick to dust."
Below is a simplified breakdown of the wildfire impact assessment for your property in Pendleton, CA. The report evaluates toxins and residues from the January 2025 Eaton Fire (burned ~14,000 acres, ~3,000 feet from your home). Sampling occurred on April 14, 2025.
1. Introduction
1. Introduction
The report assesses wildfire-related contaminants in your home. Key methods included:
Tape-lift samples (37 surfaces): Tested for soot/char/ash.
Heavy metal wipes (7 indoor/outdoor surfaces): Tested for lead & other metals.
Air sampling (1 dining room sample): Checked for toxic gases (VOCs).
Soil testing (1 composite sample).
2. Key Findings
2. Key Findings
A. Combustion Particles (Soot/Char/Ash)
Elevated levels (4-9%, "atypical") found in:
Rear Exterior Breaker Box (T-03)
Family Room Window Sill (T-04)
Typical background levels (1-3%) in 24 other areas (e.g., garage, living room).
No detection in 11 areas (e.g., TVs, picture frames).
What this means: Wildfire residues are present outdoors and in some rooms, but most areas show normal dust levels.
What this means: Lead dust requires professional cleaning in flagged rooms. No other metals pose immediate risks.
C. Air Toxins (VOCs)
Elevated levels of one chemical:
2-Furaldehyde (2.6 ng/L) in the dining room.
All other toxins (e.g., benzene-like compounds) were below detection limits.
What this means: Air quality is generally safe. The one elevated chemical may cause mild irritation but dissipates with ventilation.
D. Soil
Heavy metals (lead, arsenic, etc.) were within safe limits. No hazardous waste detected.
Immediate Actions:
Do not disturb dust in high-lead areas (Family Room, Play Room, Addition Bedroom).
Use masks/gloves during cleaning.
Wash hands after touching surfaces.

5. Recommendations
Professional Lead Abatement:
Clean Family Room, Play Room, Addition Bedroom using EPA-certified contractors.
Use HEPA vacuums, wet-wiping, and sealants (do not dry-sweep!).
General Cleaning:
Wash windows, sills, and non-porous surfaces with detergent.
Replace HVAC filters; clean ducts if residue is visible.
Post-Clean Verification:
Retest lead dust after cleanup (ensure levels <5 µg/ft²).
Long-Term:
Monitor for lingering odors or dust; repeat cleaning if needed.
6. Conclusion
6. Conclusion
Your property shows moderate wildfire impact, primarily in lead dust hotspots. While air and soil are safe, targeted cleaning in 3 rooms is critical for health safety. Schedule professional lead abatement ASAP and avoid using these areas until cleaned. The full report is available for contractor reference.
