Again, like the last pictures of the lime, this was from the field trip to the sewage treatment plant from early this passed October. Here, there dump the used lime from the water cleaning process so that it may dry. The water pooled on top is an awesome shade of blue, I tried to bring it out in the post-editing, I think I did well.

Once the water's all gone, they scoop it up and give it to the farmers. The lime is used to help control the pH in their soils and otherwise keep things under control for them.
