1. Prepare for tomorrow's check-in (solid and e-waste and water use/pollution)
2. Read 19.2 - 19.9 in Botkin and Keller and add to today's notes.
3. Complete Assignment 59. See below.
4. Review/revise your hypothesis for submission tomorrow. Of the following methods (aeration, adding alum, filtration through sand, filtration through activated charcoal, adding chlorine, fine filtration), which do you think will clean the wastewater most effectively (measured through solids being present, clarity, odor, and/or color)? Support your hypothesis.
Optional: Check out Vice's "America's Water Crisis - Part 1" if you get a chance. The narrator is a bit of a trip and there's some swearing (exciting!), but it's good content.
