A federal government sweep of 48 B.C. dry cleaning businesses found that almost half were allegedly mishandling a toxic chemical that has been linked to leukemia, kidney and liver cancers as well as depression of the central nervous system.
Last summer, Environment Canada enforcement officers found 21 businesses across B.C.鈥檚 South Coast didn鈥檛 have a 鈥渟econdary containment system鈥� to prevent the spillage of the solvent PERC or the sludgy residue it produces, according to a search warrant from the ministry.
PERC 鈥� a clear, colourless liquid with an ether-like odour that鈥檚 also known as perchloroethylene or tetrachloroethylene 鈥� is used in dry cleaning machines to remove stubborn stains and grease without wrinkling fabric.
Studies have shown that dry cleaning workers exposed to PERC were more likely to develop esophageal and cervical cancers as well as irritated and burnt skin and forgetfulness, according to the Carex Canada carcinogen surveillance program, whose team of researchers hails from University of B.C., Simon Fraser University and the University of Victoria.
So far, one business, North 91原创鈥檚 Lester鈥檚 Dry Cleaning, is facing two Environmental Protection Act charges from the sweep, while Environment Canada confirmed Tuesday that the alleged supplier of the PERC in question is still under investigation.
Long used by dry cleaners, PERC was banned in California six years ago and is facing similar pressure in other jurisdictions.
A decade ago, new federal regulations required dry cleaners to reduce their use of the chemical by 70 per cent within two years from 1994鈥檚 nationwide levels of 5,500 tonnes.
Most still use PERC in B.C., but upgrading to newer machines has meant that the proper storage and disposal of the toxic compound is no longer an industry-wide problem, according to B.C. Fabricare Association President Frank Wagner, whose organization represents about 50 out of roughly 200 dry cleaning businesses in the province.
Wagner estimated that about 20 per cent of B.C.鈥檚 dry cleaners are 鈥渂asically refusing to be environmentally responsible鈥� by using older equipment, which leads to persistent mishandling of PERC.
鈥淚 wouldn鈥檛 necessarily say the solvent itself is a problem; it is a problem if it is not handled correctly,鈥� Wagner said.
鈥淎s in any industry or business, you can choose to work with old machines or you can choose to work with newer technology 鈥� you鈥檙e able to buy the machines today that are absolutely complying with the regulations in place and are safe.鈥�
He said he would like it to be mandatory for all dry cleaners to be educated on the dangers of various chemicals used, as well as all solvents to be tracked by the authorities.
Environment Canada regulates dry cleaners and requires they send in annual reports detailing how much PERC they have used and how they have disposed of it.
No one from the provincial or federal environment ministries was available for comment Tuesday by press time.
Wagner said another part of the problem lies with global garment industry, which has only officially approved the use PERC as a cleaning solvent (as evidenced by the encircled 鈥榩鈥� found on many clothing labels).
鈥淲e鈥檙e talking about an issue of liability, too,鈥� he said. 鈥淚f the cleaner is choosing to clean with an alternative solvent, doesn鈥檛 matter which solvent it is, he is liable for (any damage).
鈥淎 few manufacturers go away from that and put 鈥榙ry clean only鈥� (on labels), which is a way of getting away from the (liability) problem.鈥�
Alan Avery, the manager of Sumas Environmental Services鈥� B.C. operations, said PERC is a dense liquid that can sink through groundwater onto bedrock if disposed improperly.
鈥淭hat鈥檚 another material that really just has to go for incineration,鈥� Avery said, adding that his company trucks its PERC to Alberta鈥檚 Swan Hills incinerator.
鈥淵ou remember ever walking into a dry cleaner years ago? There was a real strong smell when you went in there? That was it,鈥� said Avery. 鈥淵ou walk in there now and they don鈥檛 smell like that, they鈥檝e got this completely contained, closed system, so they鈥檙e super-efficient and they鈥檙e not putting out any vapours.鈥�
