Wastewatertreatment
Litho- and Atmosphere Water Water
Pollution Potpourri
Wastewater treatment - 100
Storm water
Waste water treatment plants treat sewage water along with this type of
water.
Wastewater treatment - 200
Physical
Primary treatment in waste water treatment is this type of process
Wastewater treatment - 300
Biological
Secondary treatment in waste water treatment is this type of process
Wastewater treatment - 400
Dissolved organic matter
The main purpose of the aeration tank in secondary treatment is to remove this type of pollution
Wastewater treatment - 500
UV rays, ozone gas
Chlorine has traditionally been used as a final disinfectant. However
many cities are now starting to use other methods. Name one
example.
Litho and Atmosphere - 100
Troposphere
The layer of the atmosphere where weather occurs.
Litho and Atmosphere - 200
Stratosphere
The layer of the atmosphere that is important in blocking the sun’s UV radiation.
Litho and Atmosphere - 300
CFC’s (chloroflourocarbons)
This class of compounds once used in refrigerants have the ability to breakdown “good” ozone
Litho and Atmosphere - 400
Photochemical smog
Produced when several pollutantsfrom automobile exhaust are
acted on by sunlight.
Litho and Atmosphere - 500
Kyoto Protocol
International protocol that calls for a reduction of CO2 levels to below 1990 levels. (The US has decided to not sign on to this agreement)
Water - 100
2.5 – 3.0 %
What percentage of the water on Earth is freshwater (liquid and solid)?
Water - 200
Agriculture (irrigation)
This activity uses the most water worldwide.
Water - 300
Capillary water
Water held in the soil and taken up by the roots of plants
Water - 400
Diverted to irrigate cotton fields
This is the main reason why the Aral Sea has decreased by 60%
Water - 500
Land Subsidence
The depletion of groundwater from aquifers and the building of levees preventing seasonal flooding can result in this problem.
Water Pollution - 100
Mercury
Build up of this pollutant along a food chain is what leads to Minimata disease which is also known as “dancing cat” disease
Water Pollution - 200
Erin Brokovich
She fought for the people of Hinkley, CA against PG&E whose use of hexavalent chromium contaminated the groundwater in the town
Water Pollution - 300
Biomagnification
The increase in concentration of a pollutant from one link in a food chain to another
Water Pollution - 400
PCBs
These man-made chemicals which were once used in materials for making insulation, coolants, and lubricants in transformers were found to harm wildlife in Puget Sound and other areas
Water Pollution - 500
DAILY DOUBLE !!!
Potpourri - 100
O2 - oxygen
This gas/molecule is needed and used up during the process of cell respiration and decomposition
Potpourri - 200
Point-source pollution
Water pollution that is easy to identify the source, such as a factory is defined as this type of pollution
Potpourri - 300
Fecal coliform test
This is a common water quality test that suggests that water is contaminated by animal waste
Potpourri - 400
Ogalalla aquifer
This is the largest aquifer in the US
Potpourri - 500
The Three Gorges Dam in China
This is the largest dam in the world
Earth and Geo - 500Double jeopardy This activity is the predominant cause of thermal pollution in surface waters
Water Pollution - 500
Power (electrical) plants
