3.  Groundwater Contamination - a G.I.S. view.


A MS-Word version of this is also available, for ease of following instructions.

Oxford County, Ontario, has used GIS to map various features associated with ground water.  This interactive tool is available at  http://lris.county.oxford.on.ca/maps/groundwater/  Click on the Groundwater Navigator to begin.

This program runs similarly to ArcView.  Select which features you wish to plot from the list on the right hand side, then click on "Refresh Map"; when it has redrawn, click on "Legend."

First (for practice) display all Municipal wells and all PCB storage sites.

We are particularly interested in the capture zones, aquifer recharge areas, and any possible sources of contamination.
You will be assigned to make and save a map of one of the following pairs of features  You will then  write a two paragraph analysis of what you see.  The first paragraph describes the information.  The second assesses whether or not your observations are a cause ofr concern, and why or why not.

Capture zones AND Petroleum wells
Recharge-Discharge in Shallow OB aquifer AND Petroleum wells
Recharge-Discharge in Intermed OB aquifer AND Petroleum wells
Recharge-Discharge in Deep OB aquifer AND Petroleum wells
Water quality - Overburden Aquifer AND Municipal water wells
Water quality - Bedrock aquifer AND Municipal water wells
Capture zones AND Waste disposal sites
Recharge-Discharge in Shallow OB aquifer AND Waste disposal sites
Recharge-Discharge in Intermed OB aquifer AND Waste disposal sites
Recharge-Discharge in Deep OB aquifer AND Waste disposal sites
Water quality - Overburden Aquifer
Water quality - Bedrock aquifer
