Heavy metalsin soil
Lead and other metals settle into soil from old paint, industrial use, burned structures and more. They don't break down, so they have to be found and removed.

Where metalscome from
Unlike fuel, metals don't degrade over time. Lead from old paint chipping off buildings, industrial processes, burned structures and vehicles, and historic site uses can stay in the top layers of soil for decades, which matters for anyone building, gardening or letting kids play there.
Alliance holds CDPH Lead Inspector/Assessor and lead supervisor certifications and is an EPA Lead-Safe Certified Firm, so lead and metals in soil are handled by people certified for exactly that.
Older buildings
Lead paint chips and dust around the drip line of older homes and structures.
Industrial sites
Former shops, plants and yards with metals from past operations.
Burned properties
Metals from burned buildings, vehicles and household materials in ash and soil.
