A-Tech conducted environmental screening and monitoring during soil excavation and earthmoving activities at a Site in Los Angeles. Removal and offsite disposal of the soil was necessary due to impacts from arsenic, lead, diesel-range organics and oil range organics.
A-Tech performed air monitoring during soil remediation activities due to the potential disturbance from fugitive emissions of dust. Air monitoring was intended to protect the onsite workers and adjacent community.
A-Tech screened excavated soils using an XRF instrument to assess soils for elevated arsenic and lead concentrations during excavation to determine the extent of impact and remedial delineation.
