​On March 22, 2019, EPCOR presented its proposed Lead Mitigation Strategy to the City of Edmonton's Utility Committee in response to Health Canada's recent announcement of a new Guideline for drinking water quality in Canada.

Our proposed Lead Mitigation Strategy is a comprehensive program that will enable EPCOR to proactively meet the new Health Canada Guideline by fully incorporating health, social, environmental and financial considerations. Key elements of the Strategy include:

​ 1. Adding a lead Inhibitor (orthophosphate) to Drinking Water

Orthophosphate creates a protective coating on the inside of lead pipes and plumbing that prevents lead from leaching into drinking water. It is commonly used for this purpose by water utilities across North America and the United Kingdom. It has no impact on the taste or odour of drinking water. It is naturally present in food, is a common additive to beverages and is considered to be safe. To illustrate, you'd have to drink 104 glasses of tap water to match the phosphorus in one banana. In our proposal, new orthophosphate dosing infrastructure will be in place at the two water treatment plants by the end of 2020.

​​ 2. Elimination of Partial Lead Service Line Replacements

EPCOR is proposing to end its current practice of replacing just the utility portion of a lead service line while leaving the private portion in place as it can elevate lead levels at the tap. On a go-forward basis, EPCOR is proposing to replace the private portion any time it replaces the utility portion.

3. Accelerated Replacement of High Priority Lead Service Lines

EPCOR is proposing to accelerate the replacement of any lead service lines (private and utility portions) that is above the Health Canada Guideline (based on testing) after the implementation of orthophosphate.

EPCOR's proposed Lead Mitigation Strategy is supported by both Alberta Health Services and Alberta Environment and Parks.
