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?

The annual vehicle miles (VMT) traveled by these vehicles are 8,000 miles. How many kg of CO2e does the fleet produces in a year? Which fleet of vehicles (i.e. light truck or gasoline car) produces more CO2e and by how much? Notes: Fuel efficiency of gasoline car = 23.8 mpg Fuel efficiency of light truck = 17.4 mpg Emission factor of N2O from gasoline car = 0.020 gm/mile Emission factor of CH4 from gasoline car = 0.021 gm/mile Emission factor of N2O from light truck= 0.029 gm/mile Emission factor of CH4 from light truck = 0.025 gm/mile Emission factor of gasoline = 8.78 kg CO2/gallonarrow_forward
- 28. The edges of a cast iron block weighing 32 kg were rounded off with a mill. When the block was reweighed, it was found to weigh only 29,5 kg. What percentage of the original cast iron block was lost? A. 7.8% В. 8.5% С. 3.4% D. 2.5% 29. If 3.5 L of used oil were to be disposed of each week over a three-year period, the total number of liters disposed of at the end of this time, assuming there are 52 weeks in a year, would be A. 495 L В. 546 Larrow_forwardYour neighbor lives in a 2500-square-foot (about 250 m2) older house heated by natural gas. The current gas heater was installed in the early 1980s and has an efficiency (called the Annual Fuel Utilization Efficiency rating, or AFUE) of 65 percent. It is time to replace the furnace, and the neighbor is trying to decide between a conventional furnace that has an efficiency of 80 percent and costs $1500 and a highefficiency furnace that has an efficiency of 95 percent and costs $2500. Your neighbor offered to pay you $100 if you help him make the right decision. Considering the weather data, typical heating loads, and the price of natural gas in your area, make a recommendation to your neighbor based on a convincing economic analysis.arrow_forward2.arrow_forward
