BTetrachloroethylene (PCE/PERC) contamination of soil and groundwater—a common dry cleaning solventCorrect
CAsbestos-containing insulation on the dry cleaning equipment, boilers, and steam pipes, presenting a friable asbestos hazard during any demolition or renovation
DBenzene contamination from petroleum-based solvents used in legacy dry cleaning equipment before the industry transitioned to chlorinated solvents in the 1970s

Why Tetrachloroethylene (PCE/PERC) contamination of soil and groundwater—a common dry cleaning solvent Is Correct

Answer B: Tetrachloroethylene (PCE/PERC) contamination of soil and groundwater—a common dry cleaning solvent

Dry cleaning operations commonly used perchloroethylene (PCE/PERC), a dense non-aqueous phase liquid (DNAPL) that is a persistent soil and groundwater contaminant, a known carcinogen, and one of the most common groundwater contaminants in the U.S.
