What is 'chlorinated solvent contamination' and why is it common in Delaware industrial areas?

AA type of radon contamination from chlorinated rock formations
BContamination from compounds like TCE and PCE used as degreasers in industrial and dry cleaning operations — these chemicals are dense non-aqueous phase liquids (DNAPLs) that sink into groundwater and are difficult to remediate✓ Correct
CContamination from chlorinated drinking water additives in municipal water systems
DSalt water intrusion into Delaware's coastal freshwater aquifers

Explanation

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. Properties near former dry cleaners, metal fabricators, or other industrial uses should be investigated for chlorinated solvent contamination in Phase I/II ESAs.
