Herbicides, pesticides, fertilizers, and road salts are all examples of potential __________ sources of groundwater contamination.
non point
T or F -- Aquifers confined by an overlying LOW hydraulic conductivity layer are generally less susceptible to contamination
True
A clould of contaminated ground water is called a contaminant _______.
plume
What are the two ways groundwater contaminants migrate?
Advection and dispersion
What is the EPA recommended maximum concentration of Free Chlorine in drinking water?
0.2 ppm (parts per million)
Would you expect a stream surrounded by limestone to be less acidic or more acidic? EXPLAIN.
Less acidic, the rain runs off the limestone and into the stream neutralizing it.
List two possible sources of nitrates in stream water.
animal feces, leaves/grass clippings
Would you drink from Second Creek? Explain?
No, the arsenic in it is at 100 ppm.
Name the two types of smog:
Photo chemical, sulfuris
Which gas is closely associated with acid rain?
SO2
T or F -- Cities in valleys are more susceptible to smog problems?
True
Which gas is most closely associated with the greenhouse effect?
CO2
T or F -- Most precipitation (on Earth) is slightly acidic due to the reaction between atmospheric vapor and CO2
True
List two possible environmental effects associated with acid rain:
The rain gets in waterways which kills the fish population / Kills plants / Degrades limestone.
T or F -- Atmospheric greenhouse gases increase global surface temperature, slowing the rate at which heat can leave the atmosphere.
True
List four major greenhouse gases.
CO2, SO2, H2O, O3
T or F -- Fifty years of instrumental measurements recorded at Mauna Loa, Hawaii show a negative correlation between lower atmospheric CO2 concentrations and temperature.
False
If the Greenland Ice sheet (high albedo) continues to melt, what affect will this have on global temperature?
Global temperature will rise because the ice currently reflects radiation and heat and could not if it were gone.
Municipal solid waste (MSW) is
common household trash
T or F -- Since 1960, per capita generation of MSW has been decreasing.
False
What is the most common type of MSW (by category)?
containers and packaging
List 3 ways the world could benefit from the monitoring and reduction of our personal waste:
Uses less energy, saves resources, cuts down on pollution
What is DNAPL and why are the so difficult to remove/treat?
Dense Non-Aqueous Phase Liquid, they are hard to remove because they are a very oily solvent.
The pH scale
0 - 7 - 14
0 - Most acidic
7 - Neutral
14 - Most alkaline or basic
0 - Most acidic
7 - Neutral
14 - Most alkaline or basic
Why is chlorine added to Knoxville city water?
To kill bacteria and/or coliform.
What health risks are associated with elevated nitrate levels in drinking water?
Blue baby syndrome
Explain how valleys are more susceptible to smog problems (thermal inversion).
The smog can only go up and since the sun can not pass through the smog hot air cannot lift the smog.
Why are some water systems more vulnerable to acidification that others?
Their geological location.
List 3 ways acid rain can negatively affect the environment.
Degrade limestone, kill plants, Kill fish populations
What major activity produces air pollutants which contribute to global warming, smog, and acid rain problems?
Emissions from vehicles
Since there have been several highs and lows in Temperature and CO2 concentrations in the last 400,000 years, why are we concerned now?
The earth is due for another global cooling with the CO2 concentration being so high.
As global warming occurs will the temperature increase be the same everywhere?
No, it depends on the location.
What are some environmental benefits to recycling?
It saves resources, uses less energy, cuts down on pollution
Which materials have a high rate of recycling? Which have a low rate of recycling? Why the disparity?
99% of auto batteries are recycled.
23.3% of glass containers are recycled.
There may be more money in recycling auto batteries.
23.3% of glass containers are recycled.
There may be more money in recycling auto batteries.
What is compost, what can it be used for?
Compost is organic matter such as grass clippings or food scraps that can be used as a fertilizer.
