Thank you for the question.
It depends on the basin and the system. This is what I was referring to, about trying to at least have standardization across watersheds and basins of what core water quality information should be reported and at what time. Surely in the oil sands area, naphthenic acids and those types of contaminants are very critical. They have monitoring programs in place to actually measure those types of chemicals. Those are not ubiquitous in other parts of the country.
The same thing is true with respect to municipal waste-water effluent and the complex mixtures there. We don't have, necessarily, a consistency. We have some core parameters, such as biological oxygen demand, E. coli and a few other things that are measured, including nitrogen and phosphorous, but there are many other compounds, as has been mentioned by many others, that are not necessarily ubiquitously monitored.
I think the compelling argument would be that, unlike the case with other frameworks in Europe and other areas, we should be developing, from a basin management perspective, some standardization in terms of what we expect, what we monitor and how we report on it.
