Concentration (µg/L) |
7.0 to 8.7 & Narrative |
The pH of marine and estuarine waters should fall within the range of 7.0 – 8.7 units unless it can be demonstrated that such a pH is a result of natural processes. Within this range, pH should not vary by more than 0.2 pH units from the natural pH expected at that time. Where pH is naturally outside this range, human activities should not cause pH to change by more than 0.2 pH units from the natural pH expected at that time, and any change should tend towards the recommended range. | |

CCME would like to know how you use the Canadian Environmental Quality Guidelines so we can improve them. We’d love to hear from you through this quick 4 minute survey. Thank you.
