I visited Northwest Wastewater Treatment Plant in Carbondale, IL ( 1699 New Era Rd, Carbondale, IL 62901 ). The assignment is to write Two pages summary. The points that you should talk about are located in the word file attached. Also, some requirements you need to follow.
I will attach some clips and website link to help you finish the assignment.
