1. PERC IS HEAVIER THAN WATER. Part of the reason that Perc releases are so challenging to investigate and cleanup is because of its chemical properties. PCE is over 60% heavier than water under normal conditions and sinks to the bottom while the groundwater floats on top.
When did dry cleaners stop using perc?
The new wet cleaning system was installed in 2011 and the old PERC system was removed in 2012.

How bad is dry cleaning for the environment?
Perchloroethylene is a known toxic air pollutant. Petroleum solvents used in dry cleaning operations can release some toxic air pollutants and volatile organic compounds (VOC). Chemicals in these substances can react in the air to form ground-level ozone (smog), which has been linked to a number of respiratory effects.
