The City of Saskatoon is holding a news conference this afternoon to discuss lead pipes.

This after a news report today listed Saskatoon, Regina and Moose Jaw among 11 communities in Canada which were part of an investigation into lead levels in tap water.

The investigation was led by more than 120 journalists from 9 universities, 10 media organizations, including Global News and the University of Regina School of Journalism.

The report says they interviewed nearly a thousand people and filed more than 700 requests through freedom-of-information legislation to get access to the thousands of municipal water sample test results. The investigative report says these add up to a collection of about 79,000 results since 2004.

The report alleges that in Moose Jaw, Regina and Saskatoon, homes fed by municipal lead service lines averaged 22 ppb, which is parts per billion, and that is four times the national guideline.

The City of Saskatoon brochure discussing lead pipes advises residents that lead can enter your drinking water when it sits in household lead water service pipes between uses. If your water has not been used for at least 6 hours, run the cold water faucet for about five minutes before drinking or cooking.
