Chapter 10.6, Problem 12CC

In 1980, the Environmental Protection Agency (EPA) began the Superfund Program to help clean up highly polluted areas of the environment. There are over 1300 Superfund sites across the country. Not all Superfund sites are from deliberate pollution. Some sites are old factories, where chemicals were dumped on the ground; landfills where garbage was dumped along with other poisonous waste; remote places where people secretly dumped hazardous waste because they did not know what to do with it; or old coal, iron ore, or silver mines.

According to the EPA (http://www.epa.gov/superfund/index.htm), the following groundwater contaminants were found in South Carolina Superfund sites in Greenville, Pickens, Oconee, and Anderson counties.

• Sort by city in ascending order. Examine the result: Which city appears first?
• Sort again: first by city in descending order, then by site name in descending order. Examine the results: Which site name now appears first?
• Sort again by contaminant in ascending order, then by site name in ascending order. Examine the results: Which site name appears last?
