Soil testingafter a wildfire
Burned structures, vehicles and household materials leave contaminants in the ash and the soil underneath. Sampling shows whether it's safe to rebuild.

What fireleaves behind
When a home, garage or vehicle burns, metals and other contaminants from building materials, electronics, batteries, paint and fuel can settle into the ash and the top layer of soil. Removing the visible debris doesn't always remove that contamination.
Soil sampling after debris removal confirms whether the remaining soil meets cleanup standards, or whether more needs to be excavated before the property can be cleared.
Ash sampling
Sampling of ash layers to characterize contamination before removal.
Confirmation sampling
Soil samples after debris removal to verify the site meets cleanup standards.
Targeted excavation
If results come back high, we remove the affected soil and re-test.
Results agenciesaccept
Samples are documented by location and analyzed by an accredited lab, so the results support county clearance and insurance documentation. Alliance has done soil assessment and contaminated soil removal across California for 30+ years.

Soil Testing After a WildfireFAQ
Why test soil if the debris is gone?
Contaminants from burned materials can remain in the soil after debris removal. Confirmation sampling shows whether more excavation is needed before the property is cleared.
What contaminants are common after a fire?
Metals from building materials, electronics, batteries and paint are common concerns, along with residues from fuels and household chemicals. The lab panel depends on what burned.
Is soil testing required to rebuild?
Many counties require confirmation that a burned lot meets cleanup standards before issuing clearance. Requirements vary, and we confirm yours during the assessment.
Can you test a property that didn't burn but got ash fall?
Yes. Sampling can tell owners and insurers whether ash deposits on nearby properties need cleanup.
Need soil tested after a fire?
We'll sample, explain the results and handle any excavation the property needs.
