Thank you for the question.
As I mentioned at the outset, we do work very closely with provinces and territories on the implementation of drinking water quality standards. Recently we have been working with the provinces and territories very closely on the issue of lead. We have updated our drinking water quality guidelines in a proposed format which encompasses the very data you're speaking of, in terms of new data showing effects particularly with young infants.
Through our ongoing dialogue with the provinces and territories, we have been discussing this new science. We have put it in a format in our new drinking water quality guidelines which reduces the suggested limit. From our perspective, we believe we have been communicating the up-to-date science with the provinces and territories with respect to impacts on the IQ for infants.
