In March, Los Angeles Times reporters conducted soil sampling in burn scar areas to assess contamination levels post-wildfire. They collected 40 samples from residential properties, applying rigorous methods to prevent cross-contamination and ensuring a representative analysis of soil conditions. Each sample was a composite, created from multiple cores to reflect potential variations in contamination, as differing areas of properties can experience varying levels of pollution. The samples were sent to a certified lab for testing, highlighting the importance of thorough environmental assessments after wildfires.
Composite sampling is a common practice in wildfire recovery, designed to account for varied soil conditions and provide an average across properties.
To prevent contamination, the team sanitized all equipment, changed gloves and boot covers between each property site.
