APES desalination

It's been a big few days for California.  First, groundwater regulation, then single use plastic bag regulation, and  finally the near completion of  the desalination plant in Carlsbad, near San Diego.

Here are two video links to the process of desalination and the potential impacts and natural services.
You need to either highlight and click on link, or, copy and paste.

"Scientific American"  link explaining desalination as a last resort for water shortages.

Page 335 of your book asks the question if desalination is a useful way to expand water supplies.  What do you think?

Tomorrow we'll be completing the lab.  Be creative in the variables you want to use.
