Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.
Companies using perc in consumer products, such as stain removers, or in industrial processes have under three years to do away with the chemical, the Washington Post reports. Dry cleaners will ...
The exposure to tetrachloroethylene in a typical dry cleaner is considered far below the levels required to cause any risk. [11] It is estimated that 50% to 70% of dry cleaners in the US were using PCE as of 2012. [7] Alternative solvents are available, but these may require major changes in equipment, procedures, and operator training. [7]
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 prevalent form of phosphates that are found in household cleaners is pentasodium triphosphate (PTSP). [8] PTSP and other phosphates are unable to be fully removed during wastewater treatment. It has been linked to eutrophication, which entails excessive growth of algae, which absorbs all of the oxygen in the water. [9]
