Health Canada recently released Bromate in Drinking Water - Document for Public Consultation document summarizes the results of a re-assessment by the Federal-Provincial-Territorial Committee on Drinking Water (CDW) on available information with the intent of updating the current drinking water guideline.
The existing guideline on bromate, last updated in 1998, based its maximum acceptable concentration (MAC) of 0.01 mg/L (10 µg/L) on renal cell tumours in rats. The new document:
- identifies mesothelial tumours as the critical endpoint on which to establish a guideline;
- incorporates updated data and information related to exposure to bromate in Canada, analytical methods, and treatment considerations at the municipal and residential scales.
Based on these considerations, the document proposes to reaffirm a MAC of 0.01 mg/L (10 µg/L) for bromate in drinking water. The deadline to provide comments is February 5, 2016.
