So I took this as just another course to the required amount of science credits, but it appears that this is by far the most pricey course that I am in textbook wise.

Can anyone thats taken the course, or is taking it and has talked to profs or did some research, tell me what is really required? Here are all the available textbooks

I already have the lab manual because it is essential, but what else?
Thanks a lot.

From my experience you only really need the lab manual for this course, however it may be helpful for you to also get the handbook for earth and environmental sciences if you think you might take more environmental science courses in the future.

Im not taking any more environmental courses in the future, is it worth getting for this year? Are the textbooks unnecessary then?

I would say that you don't need to buy the textbook and as for the handbook since its only under reccommended I would say you don't need to buy that either.
