I'm an NSERC chairholder. NSERC funds our research program, along with Halifax Water.
Very detailed lead studies are still required on a utility-by-utility basis, but there is broad consensus among the scientific community that, first of all, lead is a public health concern. It affects mental health in children, and it's a legacy contaminant that stays with the child until they're in their thirties and forties. That is well accepted in the scientific community. The detailed research activities are really fine-tuning the case study for a specific utility or for a specific situation.
