To answer that question, I would like to take just a few moments to talk about why we even monitor the water at all. The water monitoring data can provide a real-world picture of the potential exposure to inform Health Canada's risk assessments in terms of pesticides that may or may not end up in the water.
Currently, Canada does not have a consistent national water monitoring program. In the absence of this information, the PMRA defaults to overly conservative assumptions, often resulting in the cancellation of uses that would otherwise not be a regulatory concern. This reduces the competitiveness of Canadian growers and compromises their ability to combat both existing and future pests.
In terms of a national, government-run program, having such a framework really would ensure quality and consistency in terms of methods of detection and sampling collection, use of thresholds that are in line with what is used by Health Canada, sampling done across Canada—including different agricultural areas—and being able to do it at a consistent frequency so that they can conduct trend analysis to understand the levels over time.
