Daily Objectives #24 (November 27, 2007)                                        Dr. Sanders

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

v Ground Water Contamination and Remediation
  • (Review)  List and describe properties of contaminants that can affect their movement through the subsurface.
  • Given information about the properties of a particular contaminant, predict how it will behave in the subsurface.
  • Given information about the properties of a particular contaminant, suggest howyou might explore for and monitor the contaminant.
  • Given information about the properties of a particular contaminant, propose an appropriate remediation plan.

Today's Agenda:

v Ground Water Contamination and Remediation

(Review) What happens to a chemical when it is introduced into the subsurface?  How might it be transported?  What processes affect its transport?  Consider advection, diffusion, dispersion, retardation, and degradation.

(Review) Given hydraulic conductivity, effective porosity, and a ground water level map, explain how to determine the time it will take for a contaminant to move from one point to another point.

What contaminant properties affect how a contaminant moves?  Consider density, solubility, vapor pressure, and so on.

Given the particular contaminants we researched (download the compiled information here (Excel file)), explain how and where each one might move.  Explain how you might monitor for each one.  Then, tell how you might remediate each one.  (Consider the remediation techniques described in your textbook.)

Take a Plume Busters "pre-test".

Take a look at Plume Busters, which we will be using for our hydro capstone experience!
