Concept explainers
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?

- Problem 2.3 The following problem can be solved using the generalized conservation and accounting principle to determine if a recycling plant is profitable annually. Operating information: ● ● The plant operates 9 hours each day, 5 days each week, and 48 weeks each year. The plant purchases 30 tons of aluminum (at a rate of $0.02/lb) during each operating week. The plant has 5 full-time employees who are paid $18 per hour. All employees work during all of the plant's operating hours. The plant produces 7 bales of recycled aluminum per day, which it sells for $950 per bale. [Note: 1 ton = 2000 lb] Answer the following questions: (a) Identify the system (in words). (b) Identify the "stuff" you are accounting for in this analysis. (c) In order to determine the plant's annual profitability, would one be interested in studying the instantaneous rate of change in "stuff" (i.e. rate form) or the total change in "stuff" over an interval (i.e. finite-time form)? (d) On a system diagram (hint:…arrow_forwardProblem 2.3 The following problem can be solved using the generalized conservation and accounting principle to determine if a recycling plant is profitable annually.
