Water Quality

The ITU World Triathlon Series Montreal is governed by the highest standards of the International Triathlon Union (ITU) swimming water quality standards. These standards are established in accordance with the World Health Organization (WHO) standards and the European public health standards. The ITU competition rules (see section 10.2, p. 43) ensure safe swimming conditions for all athletes. The Jacques-Cartier Basin meets all the requirements.



Please find below an extract on ITU swimming water test requirements according to the ITU Event Organizers’ Manual :


Water quality tests submit to ITU

  • At the time when the Local Organising Committee (LOC) announces the venue (if this takes place at least 15 months before the first competition date)
  • One year prior in the month of the event
  • Two months before the competition
  • 7 days before the competition

Additional tests may be requested from the Technical Director based on the results of the previous tests.


The ITU will cancel the swimming leg of the triathlon if water quality tests indicate results outside of accepted standards as indicated in the table below, unless the ITU Medical Commissions issues a special authorization.
