Thank you for the question. I will say, generally speaking, that one of the problems we noted in this chapter concerns the data from the Water Quality Monitoring Program. Environment Canada has no system for ensuring that the data from all the monitoring stations are reliable. That is why there is no system to ensure that the data from all the stations is accurate, or not. There is no system at Environment Canada that can assure us of this. As a result, the public can't know clearly whether there are water quality problems in certain lakes or rivers.
On the other hand, the National Hydrometric Program, for measuring water quantity, is a good system with reliable data.
