CONTRACT DATES: Sept 2021 – Nov 2021
The Former Concord Cleaners remediation project included soil excavation and disposal to remove Tetrachloroethylene (PCE) contaminated soil from an historic release from dry cleaning operations at the property.
The project site was operated as a laundry and dry cleaners from 1933 until 2017. Dry-cleaning operations ceased in approximately 2010. The source of contamination at the property is thought to be one of two chlorinated solvent (PCE) underground storage tanks (USTs) that were thought to be removed in 1988. Painted portions of remnant building foundation materials are contaminated with lead, heavy metals and polychlorinated biphenyls (PCBs).
During excavation of contaminated soil, BHE unexpectedly discovered the 10,000-gallon Underground Storage Tank (UST) filled with concrete, and the second 1,000-gallon UST; both assumed to have been previously removed.
BHE removed the 10,000-gallon UST and completed a closure in place of the 1,000-gallon UST due to the tank’s proximity to an adjacent building.
