In March 2019, Health Canada published a new lead limit for the Guidelines for Canadian Drinking Water Quality (GCDWQ). The new guideline for lead introduces two (2) fundamental changes from how lead has been managed in drinking water since 1992, namely: the maximum acceptable concentration (MAC) for lead was lowered to 5 μg/L; and more importantly, the point of compliance for lead is at the customer’s tap and no longer in the distribution system upstream from the service connection point or property line.
This impacts waterworks systems because the change in the point of compliance will require a shift in how we think about our role and responsibility in producing and distributing drinking water. The goal of waterworks systems1 (referred to as facilities in this document) is the protection of public health; and going forward, treatment and monitoring must consider the impacts of household plumbing. AEP recognizes the challenge of managing lead levels at the customer’s tap. It is a complex issue that, for some facilities, will take many years to resolve.
AEP recommends approaching lead management in two phases:
Phase 1 - Planning, communication and assessment; and
Phase 2 - Mitigation.
