Calculate the bod

Reference no: EM13181103

1. Consider a small lake, 0.4 mile across and 11 ft deep, that contains a total of 50 tons of dissolved oxygen. Calculate the BOD (i.e. calculate the amount of oxygen required to degrade the amount of organic waste given) if 6 tons of carbon-based waste is dumped into the lake. Round your answer to zero places past the decimal.

2. Repeat the BOD calculation as done in #1, but this time let's dump in 60 tons of carbon-based waste. Round your answer to zero places past the decimal.

3. The differences between the two cases above include all of the following: (Select all that apply)
In the first case there is plenty of oxygen to go around but not enough in the second case.
The BOD in the second case is larger than that in the first case.
The BOD in the first case is exactly the same as the COD.
In the first case there is a chance that the lake could recover.
Chances are, in the second case the lake will not recover.
