Learning Goal: I’m working on a environmental engineering question and need guidance to help me learn.
Select a sustainability issue of interest related to population growth. For example you can choose either the issue of: (a) population growth and food, or (b) population growth and Biodiversity. Other options are shown in the picture below:
Draw a picture representing the situation surrounding a sustainability issue. A rich picture is simply a drawing of the way you see a given situation at a particular moment in time. The quality of the art is not important. Instead what matters is that you represent all of the elements, relationships, emotions, and interactions relevant to the issue at hand. Try to use symbols and images instead of words, as this will facilitate your exploration of thoughts you haven’t already articulated. Note the ‘final version trap’ and come back to your rich picture a few times before you submit. An example of drawn picture is given below.

Learning Goal: I’m working on a environmental engineering question and need an explanation and answer to help me learn.TCE releases occurred to shallow soil from several floor drains at the Former RadiatorFactory and high concentrations of TCE are present in vadose zone soils. The highestconcentration TCE soils are have been delineated to be approximately 50 feet by 75feet. Depth to groundwater is approximately 16 feet below ground surface (bgs). Youhave been asked to evaluate the costs of excavation versus soil vapor extraction forunsaturated soils.For excavation, assume the following—-1. Labor and equipment costs to excavate and to backfill the area are $25 per cubic yard.2. Clean backfill costs $20 per cubic yard3. Pre-excavation soil sampling was performed with analysis for TCLP. Assume 30% of the excavated soil is characterized as hazardous waste ($325/ton for transport and disposal), and the remaining 70% can be disposed of as non-hazardous waste($95/ton).4. Assume bulk density of 1.65 kg/L.5. Assume an allowance for soil confirmation sampling of $10,000.For soil vapor extraction, assume the following—1. The system equipment costs $185,000 to build and deliver to the site2. A pilot test determined effective radius of influence for extraction wells to be 25 feet.3. Installation for extraction wells cost $4,000 each, including drill rig, well materials, and labor for oversight.4. Labor to install, connect, and start-up the system cost $50,000.5. Assume the system will operate for three years.6. Assume an allowance for annual sampling and laboratory analysis of $10,000For the first year assume the following O&M costs:o monthly O&M visits at $1,500 eacho quarterly granulated activated carbon change-outs cost at $8,000 eacho electricity cost of $750 per month.Assume that in the second and third years of operation the same O&M, electricity,and quarterly carbon change out costs apply as the above bullets. Assume anadditional annual O&M/repair cost of $10,000 each year in the second and thirdyears.a. Prepare a detailed cost estimate for each alternative using Section 6.0 in “A Guide toDeveloping and Documenting Cost Estimates During the Feasibility Study.” Divide costsinto Capital Costs and Operations & Maintenance Costs. To simplify this preliminarycomparison, assume 30% contingency for all capital and future costs. Calculate the totalcosts and net present value cost for the two alternatives. Assume discount factor of 7%(consistent with 2000 USACE/EPA Guidance).b. List at least one advantage of each alternative from a cost/schedule perspective. Whatoption would you recommend to a client who owns the property that is used formanufacturing? What option would you recommend to an owner who wants toredevelop the property for residential usage?c. Financial interest rates have been at historic low rates since 2009. If the discount factoris only 1% does this impact the financial comparison?
