I think that we need to deal with waste-water treatment plants that discharge into receiving waters, especially where there are issues, like Winnipeg and algal bloom issues. Places that we would want to deal with the fastest would be the target.
There's discussion at the policy level, depending on where you are in the country or in the United States, on whether we treat nitrogen or not to deal with this eutrophication or algal bloom issue. Our position is that it's very costly to deal with nitrogen and we are unconvinced that it would actually solve the problem.
Our position is that we really need to focus our resources on dealing with phosphorous from waste water and other sources.
