Some historical artifacts pose a dangerous and costly challenge to those of us living today and to future generations. Unlike stone ruins, carefully preserved books or dusty archival papers, the toxic waste produced by past industrial activities contaminate environments around the world, threatening our health and our economic future. Here in Canada, a review board just released a report on how to clean up the “237,000 tonnes of highly toxic arsenic trioxide dust stored in 15 underground chambers” that remained after the closing of Giant Mine in Yellowknife (CBC).
