Suppose you are to measure the BOD (biochemical oxygen demand) removal rate for a primary wastewater treatment plant. You take two samples of raw sewage on its way into the plant and two samples of the effluent leaving the plant. Standard five day BOD tests are run on the four samples with no seeding, producing the following data (See Figure attached) Find BOD5 for the raw and treated sewage, and the percent removal of BOD in the treatment plant. Find the DO (dissolved oxygen) that would be expected in sample two at the end of the test. What would be the maximum volume of treated sewage for Sample 4 that could be put into the 300-mL BOD bottle and still have the DO after five days remain above 2 mg/L?

Consider one farmer using an aquifer. The volume of water in the aquifer is described by Xt+1 = Xt – Yt + Qt where Xt is the volume of water in period t, Yt is the extraction of water in period t and Qt is precipitation. The marginal net benefits of the farmer in each period are described by MNBt = 20 - Yt There are two periods. The amount of water in the first period is X0 = 7 and Q0 = 1.5. The farmer cannot use more water than available at the beginning of each period such that Yt ≤ Xt. With a discount rate of 10%, what is the efficient water use in the first period?
