The water supply to a mobile park contains 0.024 ug/L of PCB. Calculate the chronic daily intake (CDI) of PCB (mg/(kg*d)) of an adult resident of the mobile park who weighs 85 kg and consumes 2.3 L of water per day.
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?
