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.

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)?

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

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
