What is the Canadian guideline for HAAs and when will it take effect?
A Canadian guideline for HAAs is under development. It could be developed, approved and take effect as early as spring 2007. Once the guideline is approved, it becomes an enforceable standard that Nova Scotia’s regulated public drinking water supplies must meet. The United States has developed a guideline for HAAs of 0.060 mg/L (or 60 µg/L).
