Benzo[a]pyrene in Drinking Water

The online consultation is now closed. Comments and suggestions received during the public consultation period are being considered. Thank you for your input.

The Federal-Provincial-Territorial Committee on Drinking Water (CDW) has assessed the available information on benzo[a]pyrene with the intent of updating its drinking water guideline. The purpose of this consultation is to solicit comments on: the proposed guideline and the approach used for its development; the potential economic costs of implementing it; the ability of accredited laboratories to reliably measure benzo[a]pyrene at or below the proposed maximum acceptable concentration; and to determine the availability of additional exposure data.

The CDW has requested that this document be made available to the public and open for comment. Comments are appreciated, with accompanying rationale, where required. Comments can be sent to the CDW Secretariat via email at If this is not feasible, comments may be sent by mail to the CDW Secretariat, Water and Air Quality Bureau, Health Canada, 3rd Floor, 269 Laurier Avenue West, A.L. 4903D, Ottawa, Ontario K1A 0K9. All comments must be received before May 6th, 2015.

It should be noted that this Guideline Technical Document on Benzo[a]pyrene in Drinking Water will be revised following evaluation of comments received, and a drinking water guideline will be established, if required. This document should be considered as a draft for comment only.
