DID YOU KNOW
As part of the initial phase of the sitewide odor assessment, workers are collecting soil samples from across the Site at depths from ~5 – 20 feet and installing soil vapor probes. Vapor samples from the probes will undergo chemical analyses and professional odor panel testing to describe the odor, determine odorous compound concentrations, and help map areas that have the potential to generate odors during future excavation for the final cleanup.
