Modern dry cleaning machines use a closed-loop system in which the chilled air is reheated and recirculated. This results in high solvent recovery rates and reduced air pollution. In the early days of dry cleaning, large amounts of perchloroethylene were vented to the atmosphere because it was regarded as cheap and believed to be harmless.
In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...
The most common chemical used by dry cleaners, though, is perchloroethylene (known as “perc”), which is highly effective but also considered a likely human carcinogen by the Environmental ...
Soil, sediments and groundwater contamination by PCBs, petroleum hydrocarbons, heavy metals and VOCs from base operations. Chemical contamination of local shellfish is no longer at levels that cause health concern but the area is closed to shellfishing because of sewage contamination from other sources.
