Evaluation of the Web sites/ Project

I've found a few websites so far for the evaluation part of our project. Can everyone please check them out and tell me what you think? I'm working on the Water Purification Processes and I figure that I will research 3 websites that have to do with that topic, since I think the processes are pretty important for our project.

Exactly WHAT are we doing for our project? Are we making a website? I thought for my lesson plan I would have my students create a blog/pamphlet on the processes. I don't exactly understand what the entire project will come together like in the end. Anyone else understand? Anyways, here are my websites that I found..and the ones I am thinking of evaluating.

Thanks everybody. Lets try to keep communicating this weekend about this project, so that we are all on the same level.
