Why Contamination from compounds like TCE and PCE used as degreasers in industrial and dry cleaning operations Is Correct

Answer B: Contamination from compounds like TCE and PCE used as degreasers in industrial and dry cleaning operations

Chlorinated solvents (TCE, PCE, TCA) were widely used in Delaware's industrial and dry cleaning operations. As dense non-aqueous phase liquids (DNAPLs), they sink through soil into groundwater, creating persistent plumes that are extremely costly to remediate.
