Monday Week Five

...some questions...

1. Why does snow (or any kind of frozen or freezing precipitation) present a specific set of water resources management issues? What are the three geographic/physiographic/hydrologic factors that determine the climatological (annual average) levels of snowfall for a particular area? What are the water quality implications of snow management?How are snow management challenges different in areas that tend to receive lots of snow vs. those that tend to receive less? How much snow does it take to cancel school in VT? How about FL?

2. How does the presences of pharmaceuticals and their metabolites in surface water downstream of WWTP effluent discharge points suggest about the effectiveness of WWTPs with regard to managing these types of chemicals? What does concentrations of Ra in water above background levels in water downstream of WWTP effluent discharge points say about the effectiveness of WWTPs with regard to managing these types of chemicals? What about isotropically light Ra?

3. How are the source and mangement options different for dissolved inorganic and organic contaminants? How come we can use activated carbon/charcol filters on dissolved organic contaminants and not inorganic?

4. What are the main sources of pathogenic microorganisms that might contaminate a water resource? What three taxa of organisms are we talking about here? Will the same management procedures work for all three groups?

5. How is sediment pollution managed? Where does it come from?

6. How is thermal pollution managed? Where does it come from?

7. How are pH challenges managed? What are the two main sources of problematically low pH?

Slides from today are on Sakai. Sorry, there will be no assigned reading for Wednesday.
