Health Canada’s December 2025 summary tables compile the Guidelines for Canadian Drinking Water Quality. The table lists maximum acceptable concentrations for aluminium, antimony, arsenic, cadmium, chromium, lead, mercury, uranium, and other non-HMI parameters. Several entries also include ALARA or operational guidance notes, but the routeable concentration values are the source-reported MACs. The document is a drinking-water guideline instrument, not a food-contaminant standard. The controlled-vocabulary routeable values from this source are captured in the structured evidence record; uranium is documented on the regulation page and gap-logged because it is outside the current CSV species vocabulary.
