By the end of today’s class, you should be able to do the following:

* List the units of measurement commonly used to report chemical concentrations.

* List the major ions typically found in ground water, and describe their sources and typical range of concentration.

* List other constituents typically found in ground water.

* List major groups of ground water contaminants and describe their nature and common sources.

* Describe the major groups of organic contaminants based on their volatility, solubility, mobility, chemical structure, and industrial uses.

* Find and print out the Federal Drinking Water Standards on the web at http://www.epa.gov/safewater/mcl.html .  Consider printing out the "Printable PDF version" at the link of the top of that page!

* Using the USEPA website at http://www.epa.gov/superfund, learn about a Superfund site.

* Describe the mechanisms by which contaminants move in ground water.

Coming next time:  Some ground water is contaminated.  You're going to install some wells to find out how bad the situation is.  Where will you put the wells?  How deep should they be?  How large should they be?  How long should the screened portion (intake) be?  It's your first day on the job, and the drillers are waiting for you to tell them where to start drilling.  What will you do?
