In Québec, the Regulation respecting the quality of drinking water states that the lead content in tap water must not exceed 10 micrograms per litre (10 µg/L) 1 after letting the water run for at least 5 minutes. Before 2001, the standard was 50 µg/L. It was lowered to 10 µg/L to conform to a Canadian recommendation issued in 1992.
