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?

Q:A city of 200,000 people disposes of 1.05 m. s' of treated sewage that
still has a BODU of 28.0 mg . L' and 1.8 mg . L' of D0 into a river.
Upstream from the outfall, the river has a flow rate of 7.08 m3. s' and
velocity of 0.37 m. s'. At this point, the BODU and DO in the river are 3.6
and 7.6 mg . L', respectively. The saturation value of DO ( at the
temperature of the river ) is 8.5 mg. L. The deoxygenation coefficient, kd
is 0.61 day' , and the reaction coefficient, kr is 0.76 day'. Assume
complete mixing and that the velocity in the river is the same upstream and
downstream of the outfall.
1- What is the oxygen deficit and the BODU just downstream from the
outfall (just after mixing, before any reaction can occur)?
2- What is the DO 16 km downstream?
3- Calculate the critical time and distance.
4- What is the minimum DO?
Select which correct evaluation of the interpretation of waste according to the Environmental Quality Act 1974.
А.
any matter prescribed to be scheduled waste, or any matter whether in a solid, semi-solid or liquid form, or in the form of gas or vapour which is emitted,
discharged or deposited in the environment in such volume, composition or manner as to cause pollution.
В.
earth, sand, rock, shales, minerals and vegetation in the soil.
C.
crude oil, diesel oil, fuel oil and lubricating oil.
D.
any natural or artificial substances, whether in a solid, semi-solid or liquid form, or in the form of gas or vapour, or in a mixture of at least two of these substances,
or any objectionable odour or noise or heat emitted, discharged or deposited or is likely to be emitted, discharged or deposited from any source which can directly
or indirectly cause pollution and includes any environmentally hazardous substances.

- Your 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_forwardPLEASE ANSWER IT WITH SOLUTION STEP BY STEP.
