To put things in perspective, of all the nuclear facilities operating in Canada, nuclear power plants, the Chalk River site, the level of tritium in drinking water supplies has always been below 20, and in most cases it is below 15. So although the guideline or the standard is 7,000, the regulatory regime that CNSC has put in place to manage releases of tritium to the environment has been very protective of public drinking water supplies. The levels of tritium in public drinking supplies are below 20 in all cases.
