PROJECT: BIRTCHER RIVERSIDE MARKETPLACE DEVELOPMENT
CLIENT: SEACOR
LOCATION: RIVERSIDE, CALIFORNIA
DESCRIPTION:
A U.S. Cold Storage facility was dismantled in preparation for construction of a theater and community rail depot in conjunction with development of the Riverside Marketplace Development project. During excavation, elevated levels of petroleum hydrocarbons were discovered. Subsequent characterization revealed substantial ash deposits with levels of total and soluble lead and copper in excess of total and soluble threshold limit concentrations (STLC & TTLC). Approximately 15,000 tons were excavated and stockpiled for treatment.
Soil-Bond, Inc. conducted an extensive chemical stabilization treatability study to evaluate the approximate reagent type, recipe, and effectiveness on the contamination present. In addition, Soli-Bond, Inc. was contracted to utilize its Transportable Treatment Unit (TTU) which is permitted through the State of California Department of Toxic Substance Control (DTSC) for treatment of heavy metals, under Permit-by-Rule (PBR).
Remedial actions included screening of all material prior to treatment, chemical stabilization, and stockpiling for successful treatment verification.
All 15,000 tons of materials were successfully treated over a 10-day period. Upon successful reduction of soluble lead, copper and TRPH concentrations, the material was granted reclassification as non-hazardous fill, and approved for use as backfill for parking and building areas.
