Maxxam Analytics has kindly allowed me to post their very useful Reg 153 Comparison Charts (2004 vs 2011) tables, comparing the 2004 soil and groundwater cleanup standards to the new ones that came into effect July 1, 2011. The Ministry of the Environment confusingly named these the Soil, Ground Water and Sediment Standards for Use under Part XV.1 of the Environmental Protection Act, April 15, 2011. I use them constantly. Thank you so much, Maxxam!
